What is high performance Computing, examples of OpenMP, MPI and Pthreads. How obtain HPC benefits using OpenSolaris. This version was presented at OpenSolaris Day in Porto Alegre, Brazil, in April 16, 2008.

4. Computational fluid dynamics

5. Finite Element Analysis

6. Serial Computation problem instructions CPU

8. Parallel Computing problem CPU CPU CPU parts instructions

16. Threads Model Memory CPU CPU CPU CPU

17. Threads Model

18. Message Passing Model Memory CPU Memory CPU Memory CPU Memory CPU x=10

19. Hybrid Model x=10 Memory CPU Memory CPU Memory CPU CPU Memory CPU CPU
