Dear Ralph, that would be great if you could give it a try. We have been hoping for it for a year now and it could greatly benefit us if this is fixed!! :-) Thanks! Suraj On Fri, Sep 13, 2013 at 5:39 PM, Ralph Castain wrote: > It has been a low priority issue, and hence

Re: [OMPI devel] shmem build failures

Here's some more compile errors from outside of the f77 directory. Do we need to turn off the shmem build on the nightlies until these compile errors are fixed? - make[1]: Entering directory `/nfs/deep-thought/home/data/jsquyres/scratch/svn/ompi/oshmem/mca/memheap' CC

[OMPI devel] shmem build failures

I did a manual build on eddie (the OMPI build server); here's all the failures from the f77 directory. Please fix -- this is preventing nightly builds from occurring... - [14:03] eddie:~/svn/ompi/oshmem/shmem/f77 % make -k |& tee ../../../make.out CC start_pes_f.lo CC

It has been a low priority issue, and hence not resolved yet. I doubt it will make 1.7.3, though if you need it, I'll give it a try. On Sep 13, 2013, at 7:21 AM, Suraj Prabhakaran wrote: > Hello, > > Is there a plan to fix the problem with MPI_Intercomm_merge

Yes, it appears the send_requests list is the one that is growing. This list holds the send request structures that are in use. After a send is completed, a send request is supposed to be returned to this list and then get re-used. With 7 processes, it had reached a size of 16,324 send

Hello, Is there a plan to fix the problem with MPI_Intercomm_merge with 1.7.3 as stated in this ticket? We are really in need of this at the moment. Any hints? We face the following problem. Parents (x and y) spawn child (z). (all of them execute on separate nodes) x is the root. x,y and z do

[OMPI devel] oshmem fortran interface

2013-09-13 Thread Jeff Squyres (jsquyres)
The open shmem Fortran iterface is quite definitely not a Fortran 77 interface (there have not been Fortran 77 compilers in over 30 years). Can we rename the oshmem/shmem/f77 directory to be oshmem/shmem/fortran? Also, there should be no shmemf77 and shmemf90 wrappers -- there should only be

Hi Rolf, I applied your patch, the full output is rather big, even gzip > 10Mb, which is not good for the mailinglist, but the head and tail are below for a 7 and 8 processor run. Seem that the send requests are growing fast 4000 times in just 10 min. Do you now of a method to bound the
