Is your OMPI installed on an NFS partition? If so, is it in the same mount point on all nodes? Most likely problem is that the required libraries were not found on the remote node > On Feb 8, 2016, at 10:45 AM, Rahul Pisharody wrote: > > Hello all, > > I'm trying to

[OMPI users] Help with OpenMPI and Univa Grid Engine

2016-02-08 Thread Rahul Pisharody
Hello all, I'm trying to get a simple program (print the hostname of the executing machine) compiled with openmpi run across multiple machines on Univa Grid Engine. This particular configuration has many of the ports blocked. My run command has the mca options necessary to limit the ports to the

I like your suggestion better -- if we can somehow report during the compile/link that the reason for the error is because Open MPI was not compiled with Fortran support, that would definitely be preferable. FWIW: my suggestion was because I wanted to convey the *reason* for the error (i.e.,

Waiting until runtime to issue this error is a terrible idea, because then the PETSc team (among others) will disparage you for allowing a user to successfully build against an unusable library. They are on-record numerous times in the past as to the evils of e.g. no-op symbols in MPI or other

The issue at hand is trying to help the user figure out that they have an open MPI built without fortran support. Perhaps we should improve the error reporting at run time to display something about the fact that you used a fortran data type but have an OMPI that was compiled without fortran

That being said, should we remove these fortran types from include files and libs when ompi is configure'd without fortran support ? Cheers, Gilles Jeff Hammond wrote: > >> BTW: is there a reason you don't want to just use the C datatypes?  The >> fundamental output
