I get the same behavior regardless of which machine I execute mpirun from. The security settings I altered were to add the user to both DCOM Access and Launch with all options set to allow. In WMI, I add the user to the CIMV2 namespace and grant all permissions except edit security. Windows firewall is turned off on both machines.
Did I leave anything out? Thanks! Charles On 2/2/2010 12:49 PM, Shiqing Fan wrote: > > Hi Charles, > > I've downloaded a fresh Open MPI 1.4.1 tarball, and built a clean > installer.
