Re: [OMPI users] Icreasing OFED registerable memory

Hi Waleed, It is highly recommended to upgrade to latest OFED. Meanwhile, Can you try latest OMPI release (v1.8.4), where this warning is ignored on older OFEDs -Devendar On Sun, Dec 28, 2014 at 6:03 AM, Waleed Lotfy wrote: > I have a bunch of 8 GB memory nodes in a

Re: [OMPI users] ISEND + IRECV in a cycle stuck

dear All, sorry for your time. I have found the solution: icount=1 DO iCPU=0,MPI%nCPU-1 IF(iCPU.NE.MPI%rank)THEN iTag=iCPU CALL MPI_ISEND(Ndata2send(iCPU),1,MPI_INTEGER,iCPU,iTag,MPI_COMM_WORLD,send_request(icount),MPI%iErr) icount=icount+1 ENDIF ENDDO

[OMPI users] ISEND + IRECV in a cycle stuck

Dear all, I have the following problem: In my program each rank has a vector, where the position indicates where I have to send the data. For example for rank 0, I have: *ALLOCATE(Ndata2send(0,MPI%nCPU-1)* *Ndata2send(:) = 0,10,10,16* where MPI%nCPU is the number of cPU, in my case 4 Thins

Re: [OMPI users] OMPI users] What could cause a segfault in OpenMPI?

I meant it works now, sorry for the confusion. Running the test revealed a warning on memory registration, which we fixed by setting unlimited in ulimit -l. Then running OMPI sample worked too. Thank you, saliya On Sun, Dec 28, 2014 at 11:18 PM, Ralph Castain wrote: > So
