My test program works fine when I run multiple processes on a single machine. $ ./mpirun -np 2 ./mpi-test
In MPI, is it possible to add new nodes after it is started? For example, I have 2 computers already running a parallel MPI application. I start another instance of this application on a third compute
A quick question about work balancing. Program processing files in parallel. Lets say size of the file is开发者_如何学编程 an approximated measure of how long it will take to process it. All files a
I see a lot of threads asking about situations with elapsed time (wall time) being less than user+kernel time, and I understand how multi-threading can cause this situation. However, when timing an ex
I have a C++ code using mpi and is executed in a sequential-parallel-sequential pattern. The above pattern is repeated in a time loop.
I\'m making a matriz multiplication program in OpenMPI, and I got this error message: [Mecha Liberta:12337] *** Process received signal ***
I\'m learning about MPI, but I have some doubts about its correct use. I\'m using MPJ Express. First of all, I compute a acyclic directed graph whose nodes represent tasks. The incoming arcs of a nod
I apologize ahead of time that I don\'t quite have the proper jargon to describe my problem, and that I have likely not given enough information.
I have a severe problem in my project. I need to send an image data to another node in the cluster. I read the images with ImageMagick, as like:
Currently I need to develop a program using MPI interface. There are several freely available MPI implementations and I wonder is there any whi开发者_JAVA技巧ch provides additional debugging tools, pl
