[OMPI users] undefined symbol error when built as a shared library

2009-09-10 Thread Ashika Umanga Umagiliya
Greetings all, My parallel application is build as a shared library (libParallel.so). (I use Debian Lenny 64bit). A webservice is used to dynamically load libParallel.so and inturn execute the parallel process . But during runtime I get the error : webservicestub: symbol lookup error: /usr/

In MPI, you must complete every MPI_Isend by MPI_Wait on the request handle (or a variant like MPI_Waitall or MPI_Test that returns TRUE). An un-completed MPI_Isend leaves resources tied up. Good point, but that doesn't seem to help. I augmented each MPI_Isend with a MPI_Wait. Now, one process

[OMPI users] Disable use of Torque at run-time

Hello, I would like to use a custom hostfile (that changes the default max_slot values for certain nodes). My understanding of the FAQ is that this is *not* possible with Torque. Therefore, is is possible to disable use of Torque at runtime (via an argument to mpirun), or do I need to recompile to
