  • No dual cpu support for VirtualBox with a CPU that doesn't support multicore?

    - by djangofan
    With VMWare it works fine and I can run multiple cores on a VMWare image. With Sun VirtualBox I can only run 1 cpu on a image. Its annoying. Why does Sun Virtualbox not work the same as VMWare in this respect?? My CPU is: XEON 3.00GHz Intel 90nm 2MBCache QUAD CPU x14 Socket 604 mPGA Family 15 Model 4(04) Stepping 3 Revision 05 MMX SSE3 XD SIV.exe tells me: No virtual machine extensions x86 with 64-bit support NO IA64 support MPS but with NO MCP 2 physical processors, 2 cores, 4 logical processors

  • Stack vs queue -based programming language efficiency [closed]

    - by Core Xii
    Suppose there are two programming languages; one where the only form of storage is one (preferred) or two (may be required for Turing-completeness) stacks, and another where the only form of storage is a single queue, with appropriate instructions in each to manipulate their respective storage to achieve Turing-completeness. Which one can more efficiently encode complex algorithms? Such that most given algorithms take less code to implement, less time to compute and less memory to do so. Also, how do they compare to a language with a traditional array (or unbounded tape, if you will) as storage?

  • Removing grub and getting a dual boot of Linux Mint and Win 8.1 working after failed attempt

    - by ThroatOfWinter57
    I gave the details of my problem at reddit: http://www.reddit.com/r/linuxquestions/comments/27qrun/more_specific_questions_about_failed_win_81mint/ tl;dr: I deleted the /, /home, and swap partitions I made for mint after realizing my installation couldn't be booted into and gave the space back to my windows partition. Running boot-repair on my mint live session messed stuff up. Now I can't even boot to my live session usb because grub is left over. Windows 8.1 does work though.

  • Making Sure Which Partition to Choose with Linux Dual Boot?

    - by user128360
    In the Linux Mint 12 LXDE the partitions are listed as nsd 1, 2, 3, 4, though I have a Windows 8 CP installation on one of the two partitions on the single hard drive. The space usage is differing in both system calculations, though still relateable. Where the partition is at around 20 GB usage in Windows 8 it will be at around 24 GB in the Linux installation menu. I am just wondering is there a certain way to choose the right partition? Also in the drop down menu regarding the boot loader, there are multiple options, which one would be the one to be chosen in this case? What about the system-reserve partition of Windows 7 (the one I am trying to overwrite)? What is happening with that?

  • How can I quickly change display settings from dual monitor to single monitor on laptop?

    - by Daren Thomas
    I have my laptop (running Windows XP SP3) at work hooked up to an external monitor. Whenever I unplug the external monitor (time to go home!) I have to manually change the display settings. This takes time and involves a lot of clicks. Is there a way to automate changing these settings? I'm thinking of a hotkey solution or a little application that I can start with Launchy to toggle between two profiles. I use the MultiMon tool for "extending" the taskbar to the second monitor - will I have to give that up?

  • Can Xen be configured to dedicate only one port of a dual-port NIC to a domU?

    - by jamieb
    I'm using CentOS 5.4 on my dom0 with a stock Xen kernel. I'm attempting to use the pciback module to hide some of the Ethernet ports from the host and reserve them for a domU I intend to use for a firewall (process described here). However, when I launch the domU, I get the following error message: Using config file "/etc/xen/firewall". Error: pci: improper device assignment specified: pci: 0000:01:04.0 must be co-assigned to the same guest with 0000:01:06.0, but it is not owned by pciback. lspci gives me the following output: 00:00.0 Host bridge: Intel Corporation 82945G/GZ/P/PL Memory Controller Hub (rev 02) 00:02.0 VGA compatible controller: Intel Corporation 82945G/GZ Integrated Graphics Controller (rev 02) 00:1d.0 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #1 (rev 01) 00:1d.1 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #2 (rev 01) 00:1d.2 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #3 (rev 01) 00:1d.3 USB Controller: Intel Corporation 82801G (ICH7 Family) USB UHCI Controller #4 (rev 01) 00:1d.7 USB Controller: Intel Corporation 82801G (ICH7 Family) USB2 EHCI Controller (rev 01) 00:1e.0 PCI bridge: Intel Corporation 82801 PCI Bridge (rev e1) 00:1f.0 ISA bridge: Intel Corporation 82801GB/GR (ICH7 Family) LPC Interface Bridge (rev 01) 00:1f.2 IDE interface: Intel Corporation 82801GB/GR/GH (ICH7 Family) SATA IDE Controller (rev 01) 00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 01) 01:04.0 Ethernet controller: Realtek Semiconductor Co., Ltd.

  • Oracle Sequences

    - by jkrebsbach
    Reminder to myself - SQL Server has nice index columns directly tied to their tables. Oracle has sequences that are islands to themselves. select seq_name.currval from dual; select seq_name.nextval from dual; currval - return current number at top of sequence nextval - increment sequence by 1, return new number   therefore - to create functionality in oracle similar to an index column - OPTION A) - Create insert trigger: CREATE OR REPLACE TRIGGER dept_bir BEFORE INSERT ON departments FOR EACH ROW WHEN (new.id IS NULL) BEGIN SELECT dept_seq.NEXTVAL INTO :new.id FROM dual; END; This will handle creating a unique identity, but will not necessarily inform process flow of identity without additional logic. OPTION B) - Select indentity into temp variable, insert whole item into tab **** When attemptint to query currval, the below error was being thrown - SELECT seq_name.currval from dual; ERROR : TABLE OR VIEW DOES NOT EXIST *** Although Oracle sys tables may have access to the sequences, that isn't to say the Oracle user may have access to those sequences - verify permissions when the system can't see object that are being reported in the object explorer.

  • Direct IO enhancements in OVM Server for SPARC 2.2(a.k.a LDoms2.2)

    - by user12611315
    The Direct I/O feature has been available for LDoms customers since LDoms2.0. Apart from the latest SR-IOV feature in LDoms2.2, it is worth noting a few enhancements to the Direct I/O feature. These are: Support for Metis-Q and Metis-E cards. These cards are highly requested for support and are worth mentioning because they are the only combo cards containing both FibreChannel and Ethernet in the same card. With this support, a customer can have both SAN storage and network access with just one card and one PCIe slot assigned to a logical domain. This reduces cost and helps when there are less number of slots in a given platform. The following are the part numbers for these cards. I have tried to put the platforms on which each card is supported, but this information can get quickly outdated. The accurate information can be found at the Support Document.  Card Name  Part Number  Platforms Metis-Q: StorageTek Dual 8Gb Fibre Channel Dual GbE ExpressModule HBA, QLogic SG-XPCIEFCGBE-Q8-N  SPARC T3-4, T4-4 Metis-E: StorageTek Dual 8Gb Fibre Chanel Dual GbE ExpressModule HBA, Emulex SG-XPCIEFCGBE-E8-N SPARC T3-4, T4-4  Additional cards added to the portfolio of supported cards. This is mainly Powerville based Ethernet cards, the part numbers for these cards as below:  Part Number  Description  7100477 Sun Quad Port GbE PCI Express 2.0 Low Profile Adapter, UTP  7100481 Sun Dual Port GbE PCI Express 2.0 Low Profile Adapter, MMF  7100483 Sun Quad Port GbE PCI Express 2.0 ExpressModule, UTP  7110486 Sun Quad Port GbE PCI Express 2.0 ExpressModule, MMF    Note:  Direct IO feature has a hard dependency on the Root domain(PCIe bus owner, here Primary domain). That is, rebooting the Root domain for any reason may impact the logical domains having PCIe slots assigned with Direct IO feature. So rebooting a root domain need to be carefully managed. Also apply the failure-policy settings as described in the admin guide and release notes to deal with unexpected cases.

  • Anyone know how to get dual screens working on a Dell E6410 laptop with Ubuntu 10.04 64 bit?

    - by Curtis
    I've installed the drivers from nVidia. When I go into the NVIDIA X Server Settings application, in the X Server Display Configuration setcion, and click the "Configure" button, "TwinView" is disabled. Also, clicking "Detect Displays" doesn't pick up my monitor (which is connected through a port replicator - keyboard and mouse in that port replicator work fine). Has anyone else seen this? Is this just a limitation of the current nvidia linux drivers?

  • Is an eee-pc with an Atom N550 dual core OK for Rails 3 development?

    - by dan
    I'm buying an Asus eee-pc 1015PEM and hope to do test-driven Rails 3 development on it. Is the CPU fast enough or too painfully slow for this? I plan on installing Ubuntu. I currently develop on a 11 inch Macbook Air 2010 model. It works fine as a Rails development machine. But for some reason I'm drawn to developing on a cheap little netbook. I don't use any IDE's, and my development workflow is mostly switching between Vim, Gnu Screen, and bash.

  • Is there going to be Twinview ( or alternative) implemented for nouveau ?

    - by lisak
    as I've had heavy issues with nvidia driver regarding performance of basic X window operations (window moving, resizing, scrolling). I switched to nouveau driver. But I lost the possibility of having dual screen that I had previously thanks to nvidia twinview feature... Anyway I rather have fluent X than dual screen, but having dual screen would be nice, so I'm wondering if there is already an nouveau alternative to nvidia's twinview or if it is going to be implemented.

  • Software Raid 10 corrupted superblock after dual disk failure, how do I recover it?

    - by Shoshomiga
    I have a software raid 10 with 6 x 2tb hard drives (raid 1 for /boot), ubuntu 10.04 is the os. I had a raid controller failure that put 2 drives out of sync, crashed the system and initially the os didnt boot up and went into initramfs instead, saying that drives were busy but I eventually managed to bring the raid up by stopping and assembling the drives. The os booted up and said that there were filesystem errors, I chose to ignore because it would remount the fs in read-only mode if there was a problem. Everything seemed to be working fine and the 2 drives started to rebuild, I was sure that it was a sata controller failure because I had dma errors in my log files. The os crashed soon after that with ext errors. Now its not bringing up the raid, it says that there is no superblock on /dev/sda2, even if I assemble manually with all the device names. I also did a memtest and changed the motherboard in addition to everything else. EDIT: This is my partition layout Disk /dev/sdb: 2000.4 GB, 2000398934016 bytes 255 heads, 63 sectors/track, 243201 cylinders, total 3907029168 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x0009c34a Device Boot Start End Blocks Id System /dev/sdb1 * 2048 511999 254976 83 Linux /dev/sdb2 512000 3904980991 1952234496 83 Linux /dev/sdb3 3904980992 3907028991 1024000 82 Linux swap / Solaris All 6 disks have the same layout, partition #1 is for raid 1 /boot, partition #2 is for raid 10 far plan, partition #3 is swap, but sda did not have swap enabled EDIT2: This is the output of mdadm --detail /dev/md1 Layout : near=1, far=2 Chunk Size : 64k UUID : a0feff55:2018f8ff:e368bf24:bd0fce41 Events : 0.3112126 Number Major Minor RaidDevice State 0 8 34 0 spare rebuilding /dev/sdc2 1 0 0 1 removed 2 8 18 2 active sync /dev/sdb2 3 8 50 3 active sync /dev/sdd2 4 0 0 4 removed 5 8 82 5 active sync /dev/sdf2 6 8 66 - spare /dev/sde2 EDIT3: I ran ddrescue and it has copied everything from sda except a single 4096 byte sector that I suspect is the raid superblock EDIT4: Here is some more info too long to fit here lshw: http://pastebin.com/2eKrh7nF mdadm --detail /dev/sd[abcdef]1 (raid1): http://pastebin.com/cgMQWerS mdadm --detail /dev/sd[abcdef]2 (raid10): http://pastebin.com/V5dtcGPF dumpe2fs of /dev/sda2 (from the ddrescue cloned drive): http://pastebin.com/sp0GYcJG I tried to recreate md1 based on this info with the command mdadm --create /dev/md1 -v --assume-clean --level=10 --raid-devices=6 --chunk=64K --layout=f2 /dev/sda2 missing /dev/sdc2 /dev/sdd2 missing /dev/sdf2 But I can't mount it, I also tried to recreate it based on my initial mdadm --detail /dev/md1 but it still doesn't mount It also warns me that /dev/sda2 is an ext2fs file system but I guess its because of ddrescue

  • Input to program without command-line arguments

    - by Core Xii
    Let's assume that there are no command-line arguments. How do you pass input data to a program? I'm thinking you'd write the input to a file with a specific name, such that the program knows to open and read it as input. However, how would one discover the name of that file? Usually, running a command-line program without arguments or with some standard help argument (e.g. \?) produces some instruction on how to use it. But given an environment with no command-line arguments, how does one discover how to operate a program?

  • How do I hookup a dual video card Crossfire rig to a single monitor?

    - by Alexed
    I just received a new Alienware box preinstalled with two nice shiny ATI 6950 graphics cards. My goal is to use both of them to give me really good resolution and frame rate on my single monitor. There's zero documentation with the Alienware box and nothing I can find online. Do I just plug the monitor into one of the cards, and expect the two cards to do magic internally? The ATI Crossfire website indicates a need for an "external crossfirex connection cable". Do I need to buy one of these? If so, what kind of cable is it? The AMD Catalyst Control Center shows the second card as "Linked" but when I go to the AMD Overdrive section, the second card is at zero temperature, and clock, suggesting it's not actually doing anything. What do I need to do to make use of both cards? Is it something that doesn't kick in until I do something graphically intensive?

  • Boots to terminal

    - by Core Xii
    I had a system running 10.04, I think. I upgraded it to 11.04, everything was fine. But then when I upgraded it further to 11.10, the system would only boot to a terminal, no desktop like before. I installed 12.04 on it instead, keeping /home which was on another partition... but it's still booting to terminal. I believe there may be some bad configuration files left over that are causing this. Looking at other similar issues, I looked for /etc/X11/xorg.conf but it doesn't exist. startx says it isn't installed. Installing nvidia-current didn't help (has GF 6600 GT video card). Alt+F7 shows a blank screen. I used the alternate installer, and didn't select any of the optional packages it prompts during installation. Should I have? How do I get it to boot to desktop like normal?

  • How to get monitor resolution of 1680x1050 using ATI Radeon HD 2600 PRO in a dual monitor setup

    - by user7651
    I have Sapphire ATI Radeon HD 2600 PRO graphics card in my Windows Server 2008 x64 machine. It has two outputs a VGA and a DVI. I have connected the DVI to my Dell 24" monitor with 1900x1200 resolution and it works 100%. The VGA I have connected to my second monitor a Samsung 22" with native resolution of 1680x1050. But the ATI driver and Catalyst control centre doesn't show this resolution as an option. If I choose a lower resolution like 1280x1024 it looks really bad and fuzzy. I searched in google and downloaded the powerstrip tool that allowed me to create a custom resolution of 1680x1050 and then this option shows up in Catalyst control centre and my 2nd monitor works fine now. But I don't want to pay for an application to choose a display resolution. Why doesn't ATI show me that option by default even though it has no problem in actually supporting the display at resolution. Is there a way to get 1680x1050 resolution using ATI drivers only ?

  • Looking for advice on using dd to backup a dual boot laptop.

    - by AvatarOfChronos
    My questions boils down to this. If I do "dd if=/dev/sda of=usbdrive" can anybody confirm that this will get everything including mbr/partition information/all four partitions and create a drive that I can swap with the failing internal drive without losing anything? If this is done while the computer is running will it still copy everything? At this point I'm afraid to shutdown the computer for fear of it never starting again. Secondly, how tolerant is dd of failing drives? Has anybody used it to recover a half dead drive before that can share any potential pitfalls? Did it get the data ok or is this going to be a hope for the best kind of situation? And lastly, If the usbdrive is larger than the failing internal drive I'll still be able to expand the partitions later so I'm not losing space? this last part seems silly to ask but with my current streak of bad luck I'll end up overwriting some magic bit and forever turning a 640gb hdd into a 500gb hdd. Also if anybody has a better solution to create a complete clone that gets everything I'm all for hearing about it. PostScript: I had been making periodic backups however when whatever miasma that killed the laptop struck it also got the NAS :( Post PostScript: both devices were on a UPS system.

  • Problems moving a rectangle in Pygame.

    - by Yann Core
    Hi guys! I'm making a game in Pygame and I want to be able to target enemy unit. I made it so when I click on them a variable "targeted" becomes true, and stays true until I click somewhere else on the screen. I also want targeted units to have a small green circle around them, so I made it in GEDIT. I have made a function that draws everything on the screen (the background, the player, objects, etc) and in the part where it draws the units it checks if the variable "targeted" is true and if it is it should move that little green circle over the enemy units. here is the code that does that: screen.blit(enemy_unit.pic, enemy_unit.rect) #draw the unit if enemy_unit.targeted == True: #if the unit has been targeted then draw a circle over it target_rect.move_ip(enemy_unit.pos) #move the circle to the unit target_rect.fit(enemy_unit.rect) #there are some bigger units and some smaller ones, so we have to "scale" the circle screen.blit(target_pic, target_rect) #actually draw the circle This doesn't work, when I target the unit the circle just appears for a 1/5 of second next (not on, but just next) to the unit and then disappears. I am sure that I am keeping a good track of "enemy_unit.pos" because I tested it (I added a piece of code that would print one units position and mouse's position every time i clicked the mouse and when i was near him the numbers were same). If you could give me a hint about what I'm doing wrong. I think its in move_ip function, but I tried just move and it didn't work either (the circle didn't even show at all)!

  • Dual monitors on Windows - How do I set a different DPI or text size on each monitor?

    - by dlux
    My laptop is a 15" wide screen running at 1600x1050, and in addition to that I connect an external 19" LCD which runs at 1280x1024. The problem with this setup is that if I increase the text size to make the laptop screen readable, the text on the external LCD is huge. Normal text on the LCD results in tiny text on the laptop. What options do I have to get around this? I'm using Windows 7 and the laptop is a ThinkPad T61 with an nVidia NVS 140M video chipset. I cannot find any per-display setting in Windows or the nVidia control panel to resolve this.

  • Is it possible that a single-threaded program is executed simultaneously on more than one CPU core?

    - by Wolfgang Plaschg
    When I run a single-threaded program that i have written on my quad core Intel i can see in the Windows Task Manager that actually all four cores of my CPU are more or less active. One core is more active than the other three, but there is also activity on those. There's no other program (besided the OS kernel of course) running that would be plausible for that activitiy. And when I close my program all activity an all cores drops down to nearly zero. All is left is a little "noise" on the cores, so I'm pretty sure all the visible activity comes directly or indirectly (like invoking system routines) from my program. Is it possible that the OS or the cores themselves try to balance some code or execution on all four cores, even it's not a multithreaded program? Do you have any links that documents this technique? Some infos to the program: It's a console app written in Qt, the Task Manager states that only one thread is running. Maybe Qt uses threads, but I don't use signals or slots, nor any GUI. Link to Task Manager screenshot: http://img97.imageshack.us/img97/6403/taskmanager.png This question is language agnostic and not tied to Qt/C++, i just want to know if Windows or Intel do to balance also single-threaded code on all cores. If they do, how does this technique work? All I can think of is, that kernel routines like reading from disk etc. is scheduled on all cores, but this won't improve performance significantly since the code still has to run synchronous to the kernel api calls. EDIT Do you know any tools to do a better analysis of single and/or multi-threaded programs than the poor Windows Task Manager?

  • Dell 15Z. Trying to output image using Mini Displayport to a Yamasaki Q270. (2560 x 1440) rez monitor. Dual DVI-D to Mini Displayport

    - by michaelcku
    I have a Dell 15Z. GT525M Video card. Updated Driver via NVIDIA. Problem is I just purchased a Yamasaki Catleap Q270 monitor. It is a (2560x1440) monitor with only a Dual DVI-D out. 15Z only has HDMI and a Mini Display Port. I got a Active Dual DVI-D to Mini Display Port Active Adapter(Linked Below). http://www.monoprice.com/products/product.asp?c_id=104&cp_id=10428&cs_id=1042802&p_id=6904&seq=1&format=2 The Setup works when i plug it into my Macbook air 13.3. However when I plug it into my 15Z it doesn't work. Tried everything I can thank of. Window control P. FN and F1. It just doesn't work. I believe the issue lies in the Mini Display Port but i can't be sure. No matter what i do, the Mini Display Port doesn't get recognized. Spent 3 hours on the phone with the XPS Tech team. They simply said it was not compatible.... Any help or suggestion would be greatly appreciated.
