Hello World.

I'm woundering if my machine can do parallel processing. Is there a list with supportet processors?

I'm using a Intel Core2Duo T7500 @ 2.2 GHz.

Your machine has two cores, so YES you can. Decompose your domain in two subdomains with the utility decomposePar, and run the parallel case as indicated in the User guide, with np being 2.

Unfortunately I'm running my linux-system in a virtual environment on a Windows machine.
I suppose the virtualbox is not supporting multiple cores.

When I do the steps to for parallel running and check the cpu workload with 'top' I have two solvers running with each nearly 50 % ...
That doesn't look like real parallel running ...

On the other hand, if I run the single solver, I get 100% workload in linux and 100% workload on EACH core in windows ...

Maybe thats all I can sqeeze out of my machine ...

I suggest simulate a simple case like lid-driven cavity with 80x80 cells or so with 1 and 2 processes and compare the computation time.

We tested damBreak and found OpenFOAM to be highly parallel. As # cores increase, the wall clock time greatly decreases - Check out also the InfiniBand topics under http://www.cfd-online.com/OpenFOAM_D...tml?1173649250
Most solvers have cases for each # procs (nproc2, nproc4...etc) and for cluster cofiguration, you just have to specify a hostfile with the mpirun command.

Hope this helps!

Well I have tested my dam break problem.
Running in parallel it's just half the time.
Obviously the virtual environment does support miltiple cores.
