I am using TotalView and am getting an MPI_Error. However, Totalview does not stop on this error and I can't find where it is occurring. I believe this also applies to GDB.

I want to learn C++ by using Vim and MinGW as compiler. I'm interesting at "C++ Primer (4th Edition)" and "C++ Primer Plus (5th Edition)" but I don't know how about it different. It has no book store that I can review those books, so I want to know, what is the different between those book and which…

Ok, so I don't want you to do my homework for me, but I'm a little lost with this final assignment and need all the help I can get. Learning about programming is tough enough, but doing it online is next to impossible for me... Now, to get to the program, I am going to paste what I have so far. This…

After more than a few questions about deciding on C++ books I thought we could make a better community wiki version. Providing QUALITY books and an approximate skill level. Maybe we can add a short blurb/description about each book that you have personally read / benefited from. Feel free to debate…

I have an MPI program which compiles and runs, but I would like to step through it to make sure nothing bizarre is happening. Ideally, I would like a simple way to attach GDB to any particular process, but I'm not really sure whether that's possible or how to do it. An alternative would be having…

I am trying to run a program with Boost MPI, but the thing is I don't have the .lib. So I try to create one by following the instruction at http://www.boost.org/doc/libs/1_43_0/doc/html/mpi/getting_started.html#mpi.config
The instruction says "For many users using LAM/MPI, MPICH, or OpenMPI, configuration…

Sometimes MPI is used to send low-entropy data in messages. So it can be useful to try to compress messages before sending it. I know that MPI can work on very fast networks (10 Gbit/s and more), but many MPI programs are used with cheap network like 0,1G or 1Gbit/s Ethernet and with cheap (slow,…

I've blogged before about the MPI Cluster Debugger in VS2010 that facilitates launching the application on the cluster and attaching the debugger (btw, a shorter version of the screencast I link to there, is here).There have been requests for the code I use in the screencast, so please find a ZIP…
