Hello Community,
I have a problem understanding the API for MPI_Irecv:
int MPI_Irecv( void *buf, int count, MPI_Datatype datatype, int source, int
tag, MPI_Comm comm, MPI_Request *request );
Parameters
buf
[in] initial address of receive buffer (choice)
count
[in] number of elements in rece

Hi there,
I have attached a little piece of code which summarizes a "bug?" that
annoys me ultimately. Issuing various calls to MPI_WIN_LOCK/UNLOCK seems
to hang some processes until a MPI_BARRIER is encountered!??

Hi,
I'm developing MPI support for XtreemOS (www.xtreemos.eu) so that an MPI
program is managed as a single XtreemOS job.
To manage all processes as a single XtreemOS job, I've developed the
program xos-createProcess that plays the role of the rsh agent
(replacing ssh/rsh) to start a process
Just to be clear: what you are launching is an orted daemon, not your
application process. Once the daemons are running, then we use them to launch
the actual application process. So the issue here is with starting the daemons
themselves. You might try adding "-mca plm_base_verbose 5 --debug-dae

The biggest issue you may have is that gnu fortran does not support all the
fortran constructs that all the others do. Most fortrans have supported the
standard plus the DEC extentions. Gnu fortran does not quite get all the
standards.Intel fortran does support them all, and I believe that portland

It looks like it was answered, too. :-)
