I'm confused by this statement. The examples pointed to are handling blocking sends and receives, while this example is purely based on non-blocking communications. In this particular case I see no hard of waiting on the requests in any random order as long as all of them are posted before the

Re: [OMPI users] MPI_Type_Create_Struct + MPI_TYPE_CREATE_RESIZED

Diego, Please find below the corrected example. There were several issues but the most important one, which is certainly the cause of the segfault, is that "real(dp)" (with dp = selected_real_kind(p=16)) is NOT equal to MPI_DOUBLE_RECISION. For double precision you should use 15 (and not 16).

Re: [OMPI users] send and receive vectors + variable length

Also, you are calling WAITALL on all your sends and then WAITALL on all your receives. This is also incorrect and may deadlock. WAITALL on *all* your pending requests (sends and receives -- put them all in a single array). Look at examples 3.8 and 3.9 in the MPI-3.0 document. On Jan 8,

Re: [OMPI users] send and receive vectors + variable length

Diego, Non-blocking communications only indicate a communication will happen, it does not force them to happen. They will only complete on the corresponding MPI_Wait, which also marks the moment starting from where the data can be safely altered or accessed (in the case of the MPI_Irecv). Thus

Hello all, Our clusters were just upgraded to both a new version of PGI (14.9) as well as openmpi (1.8.3). Previous versions were 12.1 and 1.6 respectively, and those compiled and linked just fine. The newest versions are not linking my mpi applications at all. Here's the problem:

Re: [OMPI users] send and receive vectors + variable length

With array bounds checking your program returns an out-of-bounds error in the mpi_isend call at line 104. Looks like 'send_request' should be indexed with 'sendcount', not 'icount'. T. Rosmond On Thu, 2015-01-08 at 20:28 +0100, Diego Avesani wrote: > the attachment > > Diego > > > > On 8

Dear all, I found the error. There is a Ndata2send(iCPU) instead of Ndata2recv(iCPU). In the attachment there is the correct version of the program. Only one thing, could do you check if the use of MPI_WAITALL and MPI_BARRIER is correct? Thanks again Diego On 8 January 2015 at 18:48, Diego

You are right. I didn't know that SGE used limits other than '/etc/security/limits.conf', even though you explained it :/ The resolution is by adding 'H_MEMORYLOCKED=unlimited' in the execd_params. Thank you all for your time and efforts and keep up the great work :) Waleed Lotfy Bibliotheca
