With the help from Jonathan Dursi and osgx, I\'ve now done the \"row decomposition\" among the processes:
I am trying to use the mpdboot comma开发者_运维问答nd to start 4 processors on which to run my MPI program. I created a mpd.hosts file with 4 nodes (75, 77, 79 and 80). Each of them run python 2.3.4.
This program demonstrates an unsafe program, because sometimes it will execute fine, and other times it will fail. The reason why the program fails or hangs is due to buffer exhaustion on the receivin
I\'m trying to use MPI_Barrier (OpenMPI) to force all the process to be in the same depth of a recursive call.
I come across this开发者_StackOverflow社区 term every now and then. And now I really need a clear explanation as I wish to use some MPI routines that
We only have been working on MPI for about one day in my computer programming class, and I now have to write a program for it. I am to write a program that organizes processes into two rings.
How do OpenMPI and MPICH handle security when I send MPI messages between the processes over TCP/IP sockets?
We have MPI based on 4 clusters with 16 cores each. We have a folder called notRestricted. We want to limit access of the application we run with mpiexec to file system - limit its access to write onl
I have C++ MPI code that works, in that it compiles and does indeed launch on the specified number of processors (n). The problem is that it simply does the same calculation n times, rather than doing
I am trying to figure out how much memory my program which uses MPI needs. It was suggested to use the function \"top\" to obtain the usage of memory. However, I am unclear on what the information mea
