[mvapich-discuss] MVAPICH2 VAPI and Scaling

[Vishwas Vasisht]

Hi 

The whole implementation is being done phasewise. The final implementatin will be a cluster will be 64 nodes (+  master) of dual cpu(dual core). All these nodes now I have updated with new version as suggested. 
I have given the size of cluster to come under MEDIUM.
mpd.hosts file contains 
node000 ifhn=inode000
node000 ifhn=inode000
...
node063 ifhn=inode063

If you require any information you can mail me. Please help me to get through this problem.

Regards
Vishwas

If I understood correctly, you have a 32 nodes cluster. So I am not sure
why here you use 65 as input parameter? Also, what have you put in your
mpd.hosts?

We found that you are using an old release of MVAPICH2 (0.9.3), the latest
release version is 0.9.6. Is it possible for you to update your stack? You
just need to download the tarball from our website and compile, there
should be no additional complexity than re-compiling 0.9.3.

Thanks.
