Scott, With and without the wired connection, laptop has the same hostname, and desktop has the same hostname. But laptop and desktop have different hostnames. I am using mpich2-1.2.1-win-ia32.msi on both machines. Laptop is win7 64, and desktop is win7 32. Another issue is: When I use laptop from home, if I use 3 or less processors, for example "mpiexec -user 0 -np 3 test.exe", it works; however, if I use more than 3 processors, for example, "mpiexec -user 0 -np 4 test.exe", it fails, and the more processors I specified, the earlier I can see it fails.

Jayesh, I did not run the program across machines. My laptop has 8 cores, and my desktop has 4 cores. I ran the program individually on each PC. Here is the command line: mpiexec -user 0 -np 4 test.exe What the program does is: Using the main processor (imrank = 0) to create a file and write records; after that, all processors will access this file and read the records multiple times (Open the file in read only --> Read records --> Close file --> Reopen --> And so on). Thanks.

Going through hydra's config.log I see that for some reason hydra is unable to find libtroque.so.2 which is in the path. I am going to see if passing the path as part of CFLAGS or LDFLAGS is going to fix this issue for me. -- Bharath

The relevant config.log files would help here. You can grab all of them for us with: find . -name "config.log" | xargs tar czf config.logs.tar.gz from your build directory. Then just send us "config.logs.tar.gz". -Dave On Jan 29, 2013, at 7:20 AM CST, Pavan Balaji wrote: > > Ah, the sizeof calculations? Nevermind.
