Thanks for trying out Paraview with MVAPICH!

Thanks for verifying the basic setup of MVAPICH and for going over the 
user guide suggestions.

Could you tell us which version of MVAPICH you are using on the linux 
cluster? I ask this since this function was used in a preliminary 
version of MVAPICH-gen2 which was older than MVAPICH-0.9.7 (and our 
current MVAPICH-0.9.8). This function name is still used in our 
`multi-rail' version of MVAPICH-0.9.7. A bit more crisply, there are two 
questions:

1) If you are using a version older than MVAPICH-0.9.7, then could you 
please download/install the MVAPICH-0.9.7 or MVAPICH-0.9.8-RC0 and 
verify the problem still exists?

2) Could you confirm whether you are using the multi-rail version of 
MVAPICH-0.9.7 or not.

Thanks,
Sayantan.
