Dear all,
I want to use infiniband, I am from a University in the US, my
University’s high performance center don’t have Gcc compiled openmpi
that support infiniband, so I want to compile myself.
But I have a few questions,
1.Is it ok to compile openmpi m
similar issue
happens with MPICH2 too. Can you try with message size (2G-1) bytes?

Thanks a lot! That's exactly what I was looking for.

Greetings,
I'm doing software fault injection in a parallel application to evaluate
the effect of hardwar
stand that mpirun or mpiexec would require a globally accessible

So is there any way to specify different pathnames in different nodes?
Many thanks,

Try MPI_Isend?
I have a glut application I am trying to add MPI to. In the display
callback, for rank >= 1, I want to send data to the rank =0 process. I
am not concerned at this point about sending data from the rank 0
process back to the rank >= 1 process, so my data is one direction.
Hi All:
I’ve written an openmpi program that “self schedules” the work.
The master task is in a loop chunking up an input stream and handing off
jobs to worker tasks. At first the master gives the next job to the
next highest rank. After all ranks have their first job, the master

Since each node has its own memory in a distributed memory system,
there is no such thing as "global variable" that can be accessed by all
processes. So you need to use MPI to scatter the input from rank 0
process to all the other processes explicitly.

Hi,
I am developing a runtime detector for noncrashing
bugs in MPI applications. It is capable of collecting
MPI communication and diagnose if a node is abnormal
based on its communication with other nodes.
Therefore, it is highly desirable to have a couple of
noncrashing bugs from real-life
