Re: [OMPI users] Performing partial calculation on a single node in an MPI job

Hi George and Jeff, Thank you for taking the time to respond to my query. You did inspire me in the right direction. Some of the variables involved in the calculation of B were not broadcast. In addition, a double do-loop combined with an IF statement was overwriting on the correct B values.

I should have been more precise: you cannot use Fortran's vector subscript with Open MPI. George. On Mon, Oct 17, 2016 at 2:19 PM, Jeff Hammond wrote: > George: > > http://mpi-forum.org/docs/mpi-3.1/mpi31-report/node422.htm > > Jeff > > On Sun, Oct 16, 2016 at 5:44 PM,

Re: [OMPI users] Performing partial calculation on a single node in an MPI job

Vahid, You cannot use Fortan's vector subscript with MPI. Are you certain that the arrays used in your bcast are contiguous ? If not you would either need to move the data first into a single dimension array (which will then have the elements contiguously in memory), or define specialized
