问题 I have a problem with running a python Hello World mpi4py code on a virtual machine. The hello.py code is: #!/usr/bin/python #hello.py from mpi4py import MPI comm = MPI.COMM_WORLD size = comm.Get_size() rank = comm.Get_rank() print "hello world from process ", rank,"of", size I've tried to run it using mpiexec and mpirun, but it is not running well. The output: $ mpirun -c 4 python hello.py hello world from process 0 of 1 hello world from process 0 of 1 hello world from process 0 of 1 hello

Microsoft MPI doesn't run

问题 I'm trying out Microsoft's implementation of MPI. I installed the CCP sdk from here: http://www.microsoft.com/en-us/download/details.aspx?id=239 And then in my project settings I added the include folder, the lib folder and mentioned msmpi.lib. With the remaining settings as-is, I build the program and then in the command prompt I proceed to run the program, but nothing happens after I start it up. Here's the code (It's supposed to display the id numbers for each thread): #include "stdafx.h"

问题 Getting error while running MPI cluster program in a LAN environment. I have created a master and other clients in a local LAN environment. I follow this tutorial to create a cluster and runs it, Running an MPI Cluster with in LAN mpiuser@507-12 :~/cloud/mpich-3.0.4/examples$ mpirun -np 4 -hosts 192.168.100.77, 192.168.100.78 ./icpi mpirun: Error: unknown option "-o" Type 'mpirun --help' for usage. It's saying that we should use proper tags while writing the command and then it will work. But

MPI and D: Linker Options

问题 I'm trying to use MPI with the D programming language. D fully supports the C ABI and can link with and call any C code. I've done the obvious stuff and translated the MPI header to D. I then translated a test program from Wikipedia to D. I compiled it with the following command: dmd test.d -L-lmpistubs It works when I just run ./test , and prints: 0: We have 1 processors However, when I run with mpiexec -n 8 test , it prints nothing. My understanding is that MPI executables require a bunch

问题 As per my little knowledge mpirun and mpiexec both are launcher. Can anybody tell the exact difference between mpiexec and mpirun ? 回答1: mpiexec is defined in the MPI standard (well, the recent versions at least) and I refer you to those (your favourite search engine will find them for you) for details. mpirun is a command implemented by many MPI implementations. It has never, however, been standardised and there have always been, often subtle, differences between implementations. For details
