Title: Running mpi in windows
Post by: ams_nanolab on June 7, 2016, 12:12

Is it possible to run ATK in parallel in Windows 64 bit? For linux we use the mpiexec command but how to do something similar in windows?

Yes, it works fine, same command. You can either try to use the one we ship with ATK, see the "bin/mpich" directory - or for a more complete installation framework get MPICH2 1.4.1p1 from http://www.mpich.org/. Intel MPI also works fine.

Use the -localonly option, and you may see some warning messages in the terminal but that's ok.

Thanks, I will try that.

Or if you first start "smpd -d" then you can skip the -localonly option, might work better. We're still testing the options :)
