[mpich-discuss] Windows/Linux MPICH2

[Matthew Chambers]

Hi Jayesh,

Thanks! You solved the cpi problem. I suggest naming the Windows 
executable icpi instead of cpi. :)

I'm able to run icpi and cpi between Windows/Linux now, but my target 
application that runs fine with the Linux MPD ring hangs. I get the 
startup output "Process on <hostname> is starting" from the Windows 
machine but not the CentOS machine, so the Linux job is hanging in 
MPI_Init_thread, MPI_Buffer_attach, MPI_Comm_size, or MPI_Comm_rank.

It still behaves the same after starting smpd with 
SMPD_OPTION_NO_DYNAMIC_HOSTS set to 1.

Thanks,
-Matt
