Charm++ parallel programming system

[Vlad Cojocaru <Vlad.Cojocaru AT eml-r.villa-bosch.de>]

Dear Eric,

Thanks a lot! I managed to build the net-linux-amd64-smp version with 
intel compilers 10.1 using -O1 instead of -O3. The megatest run as ./pgm 
+p2 completed correctly. Now I tried to build the 
mpi-linux-amd64-pthreads-smp version, I managed to build it correctly 
but the megatest fails with the error message below both when run as 
"./pgm +p2" or "mpirun -n1 -machinefile machines pgm +p2"

Now I have 2 questions, Is the pthreads option required when building an 
smp version for mpi charm ? What is actually the difference between 
building the mpi-linux-amd64-smp with and without pthreads option?
And the last question: Does anyone know why I get the error message below?

Thanks a lot for all the help

Best wishes
vlad
