In the MPI_THREAD_MULTIPLE mode ,every thread can use MPI_Send(),
MPI_Recv() simulately. I wonder the connection architectures behind the
implement。Does every thread have its own specific socket storage？Or all the

Hi Jeff ,Ralph and all,
It is a good news that just before , I compare the performance
of the VxWorks edition OPEN MPI and Linux edition OPEN MPI with Intel MPI
benchmark. The result is not bad. In the PingPong test ,Whatever the latency
and the bandwidth ,VxWorks edition behave as well
Hi all,
I tried to add a schedule algorithm to the pml component ,ob1 etc. Poorly I
can only find a paper named "Open MPI: A Flexible High Performance MPI"
and some annotation in the source file. From them , I know ob1 has
implemented round-robin& weighted distribution algorithm. But after

I think there are still many test needed to be launching .Maybe I'd
better to look into MTT.

Hi all ,
I tried to run the openmpi on vxworks. Now I can run program ompi_info
etc. But it failed running "mpirun ls", the error is :

It looks like opal_init failed for some reason; your parallel process is
likely to abor

You would install it on the host where you are doing development. Only the
eventual OMPI libraries get moved to the target.

Hi Castain
Does “install the autotools under

I have not personally tried, but I am pretty sure that you can install the
autotools under VxWorks - have you tried to download the latest autotool
tarballs and build them?

Hello everyone ,
For the purpose to migrate the OpenMPI to VxWorks ,I have set up a VxWorks
development environment with WorkBench 3.0. It is really a good news that
the WorkBench supports gnu building tools, bash and some frequently used
command like sed ,awd and so on but not the Autotools (A

Hello all,
In order to add some real-time feature to the OpenMPI for some research ,I
need a OpenMPI version running on VxWorks. But after going through the
Open-MPI website ,I can’t found any indication that it supports VxWorks .
