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 myself with infiniband suppo

That is a surprise - you must have som
Haha! +1 on what John says.
But otherwise, you shouldn't need root to install OMPI with ib support. If the
ib drivers are installed correctly, you shouldn't need the --with-openib
configure switches at all.

Hi,
Besides all these advices have been given, you may need to use --prefix
in configure script to override default installation directory since you
don't have root account. Also you might want to look at MVAPICH as an
alternative, an variant of MPICH2 that supports infiniband.
good luck,

Hello,
I am currently working on a Win32 program that makes some intensive
calculation, and is already written to be multithreaded. As a result, it uses
all the available cores on the PC it runs on.
The basic behavior is for the user to open a model, click the "start" button,
then the threads a

Hi,
Does anyone know if Open MPI 1.4.x works on HPUX 11i.v3?
Thanks

I have been working on slightly modifying a software package by Sean
Eddy called Hmmer 3. The hardware acceleration was originally SSE2 but
since most of our compute nodes only have SSE1 and MMX I rewrote a few

Is there anything in Ompi which is likely to cause one of the MMX
routines to be interrupted in such a way that the MMX state is not
saved? The bugs that arise when emms is not
I can't speak to what OMPI might be doing to your program, but I have a few
suggestions for looking into the Valgrind issues.
Valgrind's "--track-origins=yes" option is usually helpful for figuring out
where the uninitialized values came from. However, if I understand you
correctly and if you
