[mpich-discuss] mpich2 MPI_TEST errors

[Samir Khanal]

Hi Pavan

Thanks for the quick response and am glad that it reached the right person for a response. 

i downloaded mpich2 1.0.8 version from the official website. 

I am compiling a time-warp library with mpich2 ch3:nemesis channel.

I can run simple programs (like cpi etc), but the problem comes when i try to use the program for this library, (which works perfectly with mpich 1.2.7) it gives a mpi_test failure info. 

If you would like to compile the library and test, i can send you the whole package about 1MB in your mcs email.

I am really stuck with this. 

Samir

Samir,

Can you send the test program? If all channels are failing, it is very
likely either a problem with the test program or your configuration.
Btw, which version of MPICH2 are you using?

Regarding the new cluster, all you need to use it ch3:nemesis. In a lot
of ways, nemesis is a superset of sock, ssm and shm. The few features
that it is missing (which you'll only notice in special circumstances)
are being added in the 1.1 release of MPICH2.
