[mpich-discuss] MPI_Send in 32bit mpich2 (1.4) hangs in 64bit win7

[shridhar mohan]

Hello ,

I have been reading through the mailing lists
and i must say you guys are doing a nice job.

I started to set up MPICH2 last week.
We have cluster of 5 computers running 64-bit win 7.

I installed 64-bit  Mpich2 ver 1.4 in three of the machines.
Turned the Firewall down.

Smpd -status on each machine return's running.
However when i try to find the status of other hosts
it simply times out.

So uninstalled 64 bit and installed 32-bit as instructed
in section 9.4 of the installation guide.
Everything seems to be fine in 32 bit.
I was able to run "hello world" using multiple hosts.

But, when i try to send data using MPI_Send from
one host to the other, It simply hangs.
However, process within the same host are able to
send and receive data using MPI_Send.

This is very puzzling to me,
Am I doing anything wrong.
It will be helpful if someone can point me in the
right direction.


-Thanks
shridhar
