• CUDA Global Memory, Where is it?

  - by gamerx

  I understand that in CUDA's memory hierachy, we have things like shared memory, texture memory, constant memory, registers and of course the global memory which we allocate using cudaMalloc(). I've been searching through whatever documentations I can find but I have yet to come across any that explicitly explains what is the global memory. I believe that the global memory allocated is on the GDDR of graphics card itself and not the RAM that is shared with the CPU since one of the documentations did state that the pointer cannot be dereferenced by the host side. Am I right?

• Is putting the javascript before the closing body tag okay on an asp.net website?

  - by Jason Weber

  I pretty much stated what I have to ask. But is taking all of your external .js files and putting them before the closing body tag on your master pages okay on an asp.net website? I'm just going off of what yslow and google speed have been showing. I can't combine these javascripts, so I'm trying to load them "after page load", but doing so makes them useless; some of my jquery things don't work. I moved my .js files above the opening body tag, and they work. What am I doing wrong? And what could I do to load my .js files after page load? Thanks for any advice anybody can offer!

• Why is my regex so much slower compiled than interpreted ?

  - by miket2e

  I have a large and complex C# regex that runs OK when interpreted, but is a bit slow. I'm trying to speed this up by setting RegexOptions.Compiled, and this seems to take about 30 seconds for the first time and instantly after that. I'm trying to negate this by compiling the regex to an assembly first, so my app can be as fast as possible. My problem is when the compiling delay takes place: Regex myComplexRegex = new Regex(regexText, RegexOptions.Compiled); MatchCollection matches = myComplexRegex.Matches(searchText); foreach (Match match in matches) // <--- when the one-time long delay kicks in { } This is making compiling to an assembly basically useless, as I still get the delay on the first foreach call. What I want is for all the compiling delay to be done in advance when I compile to the assembly, not when the user runs the app. Where am I going wrong ? (The code I'm using to compile to an assembly is similar to http://www.dijksterhuis.org/regular-expressions-advanced/ , if that's relevant ).

• Is there a way to determine the current Outlook activity level?

  - by dlittau

  I am working on an Outlook 2007 Add-in in C# (VS2008) and we want to send some background email items only when Outlook is not busy doing something else. Is there a .net way to see if Outlook is busy doing other things (perhaps due to other add-ins or the like taking up CPU cycles)? Alternately, is there a way to send emails such that they never appear in the Outbox? We need a method that would not require any additional software be installed. Thanks for any input.

• What is the best way to make a game timer in Actionscript 3?

  - by Nuthman

  I have built an online game system that depends on a timer that records how long it took a player to complete a challenge. It needs to be accurate to the millisecond. Their time is stored in a SQL database. The problem is that when I use the Timer class, some players are ending up getting scores in the database of less than a second. (which is impossible, as most challenges would take at least 11 seconds to complete even in a perfect situation.) What I have found is that if a player has too many browser windows open, and/or a slow computer, the flash game slows down actually affecting the timer speed itself. The timer is 'spinning' on screen so you can physically see the numbers slowing down. It is frustrating that I cannot just open a second thread or do something to allow flash to keep accurate time regardless of whatever else is going on in the program. Any ideas?

• Measure data transfer rate over tcp using c#

  - by publicENEMY

  i want to measure current download speed. im sending huge file over tcp. how can i capture the transfer rate every second? if i use IPv4InterfaceStatistics or similar method, instead of capturing the file transfer rate, i capture the device transfer rate. the problem with capturing device transfer rate is that it captures all ongoing data through the network device instead of the single file that i transfer. how can i capture the file transfer rate? im using c#.

• Image-free, custom-styled search bar

  - by Jon

  I'm working with the designer and he sent me the following design for the search bar on our webpage: I'm very much against using images in webpage design unless completely necessary, so I'm hoping that I can recreate the whole search bar widget in CSS. I know how to do border-radius, gradients, box-shadows, etc, so that's not a problem. Question: Assuming CSS3 browser compatibility, how can I go about recreating the actual search button (the magnifying glass portion) with the double curved edge, and the slight drop shadow on the bottom left? Thoughts: My initial feeling was that the search button would be circular and free-standing, then overlap the search input div with a negative left-margin, but then I was unsure how I would get that drop shadow. Edit: I'm not completely opposed to using an image for the magnifying glass, but I've seen a similar icon created in CSS before. Would an image vs. pure CSS end up loading at the same speed, or should I do all I can do in pure CSS?

• What's the most efficient way to manage large datasets with Javascript/jQuery in IE?

  - by RenderIn

  I have a search that returns JSON, which I then transform into a HTML table in Javascript. It repeatedly calls the jQuery.append() method, once for each row. I have a modern machine, and the Firefox response time is acceptable. But in IE 8 it is unbearably slow. I decided to move the transformation from data to HTML into the server-side PHP, changing the return type from JSON to HTML. Now, rather than calling the jQuery.append() time repeatedly, I call the jQuery.html() method once with the entire table. I noticed Firefox got faster, but IE got slower. These results are anecdotal and I have not done any benchmarking, but the IE performance is very disappointing. Is there something I can do to speed up the manipulation of large amounts of data in IE or is it simply a bad idea to process very much data at once with AJAX/Javascript?

• Through Java, make a call to Javascript functions on networked device?

  - by stjowa

  I am doing device monitoring on a networked system. I need to know how to make Javascript calls on that device via its IP address to get certain status information (this device's status is only available through Javascript APIs, not SNMP, etc). I am working in Java. ADDED: The specific device is an Amino set-top-box. It has what it calls JMACX: JavaScript Media Access Control Extensions API specification. It allows you within an HTML document to use that API to get MUCH information about the device (cpu usage, channel info, remote-control options, etc.). I need to get this information within a Java program for specific monitoring purposes. Perhaps possible with HTTP requests? Any input would be greatly appreciated. Thanks, Steve

• C/C++ function definitions without assembly

  - by Jack

  Hi, I always thought that functions like printf() are in the last step defined using inline assembly. That deep into stdio.h is burried some asm code that actually tells CPU what to do. Something like in dos, first mov bagining of the string to some memory location or register and than call some int. But since x64 version of Visual Studio doesent support inline assembler at all, it made me think that there are really no assembler-defined functions in C/C++. So, please, how is for example printf() defined in C/C++ without using assembler code? What actually executes the right software interrupt? Thanks.

• How to reduce latency of data sent through a REST api

  - by Sid

  I have an application which obtains data in JSON format from one of our other servers. The problem I am facing is, there is is significant delay when when requesting for this information. Since a lot of data is passed (approx 1000 records per request where each record is pretty huge) is there a way that compression would help reducing the speed. If so which compression scheme would you recommend. I read on another thread that they pattern of data also matters a lot on they type of compression that needs to be used. The pattern of data is consistent and resembles the following :desc=>some_description :url=>some_url :content=>some_content :score=>some_score :more_attributes=>more_data Can someone recommend a solution to how I could reduce this delay. They delay is approx 6-8 seconds. I'm using Ruby on Rails to develop this application and the server providing the data uses Python for the most part.

• How do I implement jQuery image cycle loops on rollover for multiple thumbnail sets on a page?

  - by Kendrick Ledet

  Here is the Javascript I currently have <script type="text/javascript"> $(function() { $('.slideshow').hover( function() { $('.slides').cycle('resume'); }, function() { $('.slides').cycle('pause'); } ); $('.slides').cycle({ fx: 'fade', speed: .3, timeout: 280, next: '#next', prev: '#prev' }).cycle("pause"); }); </script> It works; but the thing is it works for all thumbnail sets on the page, and whenever I mouseover on one set of images, every other set of images loops as well. I do see that this is because I'm targeting classes, but my jQuery experience is quite limited so I have no idea how to only target a single instance of each class without effecting the others, and I can't go in and hardcode id's because my thumbnails and amount of videos on each page are determined dynamically via this Django template. http://pastebin.com/nf42bSAx I would greatly appreciate any help, as this is essential for my project (open source media platform). Thank you.

• Why use threading data race will occur, but will not use gevent

  - by onlytiancai

  My test code is as follows, using threading, count is not 5,000,000 , so there has been data race, but using gevent, count is 5,000,000, there was no data race . Is not gevent coroutine execution will atom "count + = 1", rather than split into a one CPU instruction to execute? # -*- coding: utf-8 -*- import threading use_gevent = True use_debug = False cycles_count = 100*10000 if use_gevent: from gevent import monkey monkey.patch_thread() count = 0 class Counter(threading.Thread): def __init__(self, name): self.thread_name = name super(Counter, self).__init__(name=name) def run(self): global count for i in xrange(cycles_count): if use_debug: print '%s:%s' % (self.thread_name, count) count = count + 1 counters = [Counter('thread:%s' % i) for i in range(5)] for counter in counters: counter.start() for counter in counters: counter.join() print 'count=%s' % count

• directory monitoring

  - by foz1284

  Hi, What is the best way for me to check for new files added to a directory, I dont think the filesystemwatcher would be suitable as this is not an always on service but a method that runs when my program starts up. there are over 20,000 files in the folder structure I am monitoring, at present I am checking each file individually to see if the filepath is in my database table, however this is taking around ten minutes and I would like to speed it up is possible, I can store the date the folder was last checked - is it easy to get all files with createddate last checked date. anyone got any Ideas? Thanks Mark

• In-memory data structure that supports boolean querying

  - by sanity

  I need to store data in memory where I map one or more key strings to an object, as follows: "green", "blue" -> object1 "red", "yellow" -> object2 I need to be able to efficiently receive a list of objects, where the strings match some boolean criteria, such as: ("red" OR "green") AND NOT "blue" I'm working in Java, so the ideal solution would be an off-the-shelf Java library. I am, however, willing to implement something from scratch if necessary. Anyone have any ideas? I'd rather avoid the overhead of an in-memory database if possible, I'm hoping for something comparable in speed to a HashMap (or at least the same order of magnitude).

• SqlAlchemy hangs after adding record in MS SQL

  - by Patrick

  I'm running SQLAlchemy on Jython and trying to connect to a MS SQL database using jTDS with windows authentication. I can query and delete just fine but when I try to insert new values it will hang when I commit. int 'before add' session.add(newVal) print 'after add' session.commit() print 'after commit' I see the first two print statements but not the last. My CPU maxes out and I can't even query the table directly using the MS SQL Management Studio. When I kill the Jython java process I can query again but the new values haven't been added. Strangely enough I can insert values directly using an SQL command: insert_sql = "INSERT INTO my_table (my_value) VALUES ('test_value')" session.execute(insert_sql) session.commit() Any ideas what I'm doing wrong?

• Small questions on data structure

  - by John Graveston

  Hi, I'm trying to search the parent of a node with Kruskal's algorithm. My program works just fine, but I think I have heard of a method to improve the speed of the algorithm by reconstructing the tree while searching for the parent node and connecting it to the parent node. I'm pretty sure that I've heard of this somewhere, maybe in a lecture. Can anyone refresh my memory? And also, given a number of arrays, when searching for the minimum and the maximum value from a certain section of an array, what is the name of the tree that can calculate the minimum/maximum value from the array by making a binary tree that has the minimum/maximum value of each array in O(log N)?

• 32/64 Bit Question

  - by user48408

  Here's my question. What is the best way to determine what bit architecture your app is running on? What I am looking to do: On a 64 bit server I want my app to read 64 bit datasources (stored in reg key Software\Wow6432Node\ODBC\ODBC.INI\ODBC Data Sources) and if its 32 bit I want to read 32 bit datasources, (i.e. Read from Software\ODBC\ODBC.INI\ODBC Data Sources). I might be missing the point, but I don't want to care what mode my app is running in. I simply want to know if the OS is 32 or 64 bit. [System.Environment.OSVersion.Platform doesn't seem to be cutting it for me. Its returning Win32NT on my local xp machine and on a win2k8 64 bit server (even when all my projects are set to target 'any cpu')]

• Creating a sub site in SharePoint takes a very long time

  - by denni

  Hi, I am working in a MOSS 2007 project and have customized many parts of it. There is a problem in the production server where it takes a very long time (more than 15 minutes, sometimes fails due to timeouts) to create a sub site (even with the built-in site templates). While in the development server, it only takes 1 to 2 minutes. Both servers are having same configuration with 8 cores CPU and 8 GIGs RAM. Both are using separate database servers with the same configuration. The content db size is around 100 GB. More than a hundred subsites are there. What could be the reason why in the other server it will take so much time? Is there any configuration or something else I need to take care? Thanks a lot, all helps are appreciated.

• SqlDataAdapter.Fill suddenly taking a long time

  - by WraithNath

  I have an application with a central DataTier that can execute a query to a data table using an SQLDataAdapter. None of this code has changed but now all queries are taking at least 10x as long to execute a query returning even one record. The only difference is that I have been using the app in a VM but the issue has started mid way through using the application. eg, the speed issue has not manifested itself from the start of using the VM, rather half way through. Has anyone else had an issue with the SQL Data Adapter taking a long time to fill for no reason? executing the query in Management studio it runs in less than a second. Firewalls are disabled

• Hold most of the object in cache/memory insted of database?

  - by feiroox

  Hi All, It just occurred to me why not to have most of the objects in a cache(memory) when an application start. if it's not that large web application. Or to have a settings for how much I want to put in the cache/memory. I just guess it could require to have something like below 1 GB RAM or a lot less. Everything in order to speed up the application even more by not querying database. Is it good idea?

• Does SetThreadPriority cause thread reschedulling?

  - by Suma

  Consider following situation, assuming single CPU system: thread A is running with a priority THREAD_PRIORITY_NORMAL, signals event E thread B with a priority THREAD_PRIORITY_LOWEST is waiting for an event E (Note: at this point the thread is not scheduled because it is runnable, but A is higher priority and runnable as well) thread A calls SetThreadPriority(B, THREAD_PRIORITY_ABOVE_NORMAL) Is thread B re-scheduled immediately to run, or is thread A allowed to continue until current time-slice is over, and B is scheduled only once a new time-slice has begun? I would be interested to know the answer for WinXP, Vista and Win7, if possible. Note: the scenario above is simplified from my real world code, where multiple threads are running on multiple cores, but the main object of the question stays: does SetThreadPriority cause thread scheduling to happen?
