[mpich-discuss] Fatal error in MPI_Init

[Jayesh Krishna]

Hi,
 Good to know MPICH2 is working for you now.
 Typically Infiniband adapters allow you to run TCP/IP apps above IB (They support TCP/IP sockets). Looking at the error message that you got it looked like the particular Infiniband adapter did not provide a service provider for TCP/IP apps. Anyway, good to know it is working for you now.
 The next release of MPICH2 will include a channel (nd) that supports IB (mpiexec -n 2 -channel nemesis:nd mympipgm.exe would work). You might want to try that out.

Regards,
Jayesh

Jayesh: 
I appreciate your quick response! 
Finally I could run the "HelloWorld" program! 
The problem was that I was not running smpd.exe in the 2nd PC. 
Maybe MPICH2 libraries supports the "Mellanox" InfiniBand adapters I have on both PCs. 
Now, I can run: mpiexec -hosts 126.1.20.168 126.1.20.169 HelloWorld.exe 
and it functions!!! 
I don't know how, but it functions! 

Thanks, 
Gustavo Uribe

Also, the version that I provide you will be an experimental support for Network Direct (performance tuning is in the works... and I haven't had a chance to run it on a large system to weed out all the bugs.).
