Hi,
I am running an OpenMPI program on a linux cluster with 4 quad cores per node.
I use qstat -n jobID to check how many processes working in parallel and find
that :

Hi,
I need to define a (Open MPI) MPI_Datatype in a header file so that all other
files that include it can find it.
I also try to use extern to do decleration in .h file and then define them in
.cpp file.
But, I always get error:
undefined reference
It is not allowed in Open MPI ?
Why ?

I know this.
but, what if sender can send a lot of messages to receivers faster than what
receiver can receive ?
it means that sender works faster than receiver.
Any help is appreciated.

I need to set up a kind of asychronous communication protocol such that message
senders and receivers can communicate asychronously without losing anymessages
between them.
I do not want to use block
nto it ?
Do I need to install SOAP+TCP on my cluster so that I can use it ?
Any help is appreciated.

Hi, all:
I need to design a task scheduler (not PBS job scheduler) on Open MPI cluster.
I need to parallelize an algorithm so that a big problem is decomposed into
small tasks, which can be distributed to other worker nodes by the Scheduler
and after being solved, the results of these tasks ar
Hi,
I am installing BLACS in order to install PCSDP - a parallell interior point
solver for linear programming.
I need to install it on Open MPI 1.2.3 platform.
I ahve installed BLAS, LAPACK successfully.
Now I need to install BLACS.
I can run "make mpi" successfully.
But, When I run "ma
HI,
I need to transfer data from multiple sources to one destination.
The requirement is:
(1) The sources and destination nodes may work asynchronously.
(2) Each source node generates data package in their own paces.
And, there may be many packages to send. Whenever, a data package
