[openib-general] openMPI for 2.6.17.10 kernel

[david elsen]

Steve,
   
  Thanks a lot for the reply. 
   
  I could run the cpi from the example directory. 
   
  But I see some error message when trying to run the IMB-MPI1. I am using 219297_IMB_2.3. Which version are you using?

I've run IMB benchmarks (aka pallas) on mvapich2 0.9.8 over iwarp. The
mvapich2 user guide explains how to start up mpd daemons and use
mpiexec. Its fairly straight forward. You need ssh or rsh access and
you need to setup a few files. 

Then pull down IMB and build it.

To run 2 node IMB-MPI1 tests, you do something like this:

$ mpdboot -n 2
$ mpiexec -n 2 
/IMB-MPI1 

This will run the entire MPI1 suite.



Steve.
