Hi, 
Summary: 
--------------- 
On Windows when I execute the following command (working on a fairly large dataset): 
mpiexec -hosts 2 usctap3825 15 usctap3488 1 \\fs1\correlatempi.exe cfg.xml in.h5 out.h5 debug 
I encounter an MPI gather error (read from socket failed (errno 10055). See error stack at end of this message. If I run on only one computer (with 16 cores): 
mpiexec -hosts 1 usctap3825 15 \\fs1\correlatempi.exe cfg.xml in.h5 out.h5 debug 
the program runs successfully. 

Additionally, both of the above commands run successfully on mpich2 v1.2.1 (although I had to build on mpich2 1.2.1 and used different servers that are configured exactly like the origian servers noted above (e.g., usctap3825, 16-core, 64GB memory, etc). 

I noticed that a similar error was fixed in mpich2-1.2 ( http://trac.mcs.anl.gov/projects/mpich2/ticket/895 ). Could this have regressed? tia. 

System Configuration: 
-------------------------------- 
Server1 (usctap3825) 
------- 
a. Windows Server 2003, 64-bit, SP2 
b. 16 cores/processors 
c. 64GB memory 
d. Physical computer 
Server2 (usctap3488) 
------- 
a. Windows Server 2003, 64-bit, SP2 
b. 2 cores/processors 
c. 8GB memory 
d. Virtual Machine
