[mpich-discuss] Fatal error in MPI_Init

[Jayesh Krishna]

Hi,
 It looks like the adapter (driver) does not allow creating TCP/IP sockets (There is no service provided for TCP/IP).
 The next version of MPICH2 on Windows will have a Network Direct module that should allow you to run your application over Infiniband. I don't know when the next version will be out (~ 1-2 months), if you need it sooner please let me know and I can provide a custom build for you.

(PS: Currently MPICH2 on Windows has support for only plain TCP/IP sockets. It does not support Winsock direct or Network Direct.)
Regards,
Jayesh

Hello everybody! 

I'm newbie with MPI, so I think I need your help! 
I want to tell you what is my problem: 
I have 2 computers connected with Infiniband adapters. On both PCs I'm running Windows XP, and I have installed the correspondent drivers. Then I configured the subnet, and it's possible for me to ping one PC with the other. 
After that, I installed MPICH2 (for Windows). 

I want to run a simple "Hello World" program (programmed in C), but in the moment when I want to run the program using MPIEXEC, I obtain the following message: 

Fatal error in MPI_Init: Other MPI error, error stack: 
MPIR_Init_thread<388>..........: 
MPID_Init<315>.................: channel initialization failed 
MPDIDI_CH3_Init<38>............: 
MPID_nem_init<234>.............: 
MPID_nem_newtcp_module_init<90>: 
MPID_nem_newtcp_module_init<89>: unable to create a socket. No se puede cargar o inicializar el proveedor de servicios solicitado. 
<errno 10106> 


Am I doing something wrong? 
Please! Help me! I'm newbie with MPI. 

Thanks!
