Hi,
I am a newbie to OpenMPI.
Can anyone say how the support for MPI_THREAD_MULTIPLE is implemented in
openMPI?
Is thread safety completely provided in openMPI? or does it still has some
bugs?
I am currently using LAM/MPI.But i need concurrent threads making MPI calls.
So i am planning
Hi ,
I am a newbie of openMPI.
I was running LAM/MPI. I was able to buld latest version of lam 7.1.2.
I am using RedHat 9(shrike).
Do i need additional libraries to build openMPI? Can i just build in a simple
way as in LAM/MPI?
Are there any equivalents of lamboot,lamclean, wipe, lamg
Hi,
I want to use phtreads with openmpi.
Does it configure with pthreads enabled by default or what options do i need
to mention?
Thanks,

MPI_THREAD_MULITPLE is "somewhat" supported, meaning that support for it
was designed in to Open MPI, but it has not been fully stress tested.
As such, there is likely to still be bugs when using multiple user
threads with MPI_THREAD_MULTIPLE.
fork() is not technically supported by the MPI standa
You should probably look at the README file that is included with Open
MPI -- it has instructions for compiling and installing Open MPI.
Additionally, there is quite a bit of information in the Open MPI FAQ,
particularly under the "Building Open MPI" section
(http://www.open-mpi.org/faq/?category=b
Based on your questions from the LAM list, I think you are actually
asking how to get support for MPI_THREAD_MULTIPLE (which will include
pthread support on Linux systems).
Use the --enable-mpi-threads option to configure to enable support for
MPI_THREAD_MULTIPLE (please see the README file for m
Open MPI is based on a component architecture, where plugins are used
for various types of back-end functionality.
For MPI point-to-point communication, there are three types of plugins
that are used:
- pml: Point to Point Messaging Layer (what is directly invoked behind
MPI_SEND and friends). T
Actually there was further output. I've done this too many times and I didn't verify that make.out ended where my screen output ended. I have included make.out with the extra error messages appended. Meanwhile I'm going to try using fink as someone suggested g9 from that route might work.

Jeff,
How about writing applications that use the OMPI plugins as-is? Suppose
I want to write an application that makes use of generic byte-movement
operations. Is it feasible to write my applicaiton to use a btl plugin?
- my apologies in advance if this is well covered in the docs you
men
No worries - these are good questions. :-)
Yes, it is very much our intent to allow these generic byte-transfer
plugins to be used by things other than MPI. MPI is currently the focus
and is what HPC is using *today* (and probably for quite a long time --
oodles of today's applications will be
