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 ic

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 m
