Intel MPI Fatal error

[Elvis_H_]

Hi,

I have a following problem:

I have two computer, one is master and one is slave, want to do the distributed computing.

OS are WIN7. Master's CPU is I5-3230M and slave's CPU is i7-5500U.

First, I installed Intel MPI for each one and do the test.

Testing in single one is fine, but the follow problem has come from as below.

1. I use the command on CMD as

app.exe -machines master:1:slave:1 -mpitest

it can successfully compute.

2. But I do the command as below

app.exe -machines slave:1:master:1 -mpitest

then show up a fatal error

01	Fatal error in MPI_Init: Other MPI error, error stack:

02	MPIR_Init_thread(784)................:

03	MPID_Init(1323).......................: channel initialization failed

07	gen_cnting_fail_handler(1822)........: connect failed - The semaphore timeout period has expired.
