Hi, openib maillist:
I have a cluster installed CentOS 4.4 -- which embedded the OFED
packages(under /usr/ofed directory). All infiniband drivers and libraries
have been installed and I have configured IPoIB, it also works well. The
OFED version is 1.0 -- maybe.
Now I am trying to install MVAPICH so that I can run my MPI applications
over Infiniband. The MVAPICH's version is 0.9.8 -- the latest stable
version. I modified make.mvapich.gen2 script_(set the IBHOME to /usr/ofed,
and set the IBHOMELIB to /usr/ofed/lib64, this directory contains
libibverbs.so, libibcommon.so....., etc.), the installation was successful
(MVAPICH recognized my HCA adapter -- Mellonox PCI-Express SDR, and it
seems that there were no errors during configure, make and install).
Then I wrote a simple mpihello.c program to verify the installation. This
program just printf "helloworld" in every process. I used mpicc to compile
it and when I run it, the problem occurs:
[EMAIL PROTECTED] testcodes]$ /usr/local/mvapich/bin/mpirun -np 4 -hostfile
hostfile2 mpihello
libibverbs: Warning: couldn't load driver

mpirun: executable version 1 does not match our version 3.
done.
I have two questions here:
1. Why the libibverbs wants to find the libraries in
/usr/ofed/lib64/infiniband directory? The libraries are under
/usr/ofed/lib64 directory but I still copied all the libraries files
into the /usr/ofed/lib64/infiniband, whereas the problems still exist.
2. What does the error messages list above mean? How to solve it? I have
also tried the command: /usr/local/mvapich/bin/mpirun_rsh -np 4 -hostfile
./hostfile2 ./mpihello , this also cannot be executed, the error message is
the same.
Thanks. Any suggestions are greatly appreciated.
