Scientific ComputingLecture 10 Dr. Guy Tel-Zur
Agenda • Hybrid MPI+OpenMP • PDEs – continued from last lecture • Fourier Transform – Theory, FFT and Parallel FFT • Solution of EXE #1 • EXE #3 (last) • Star HPC • Hybrid Parallel Computing (MPI + OpenMP) • New Kind of Science & Condor demo • OpenFoam
Star-HPC • http://web.mit.edu/star/hpc/index.html • StarHPC provides an on-demand computing cluster configured for parallel programming in both OpenMP and OpenMPI technologies. StarHPC uses Amazon's EC2 web service to completely virtualize the entire parallel programming experience allowing anyone to quickly get started learning MPI and OpenMP programming.
Hybrid MPI + OpenMP Demo Machine File: hobbit1 hobbit2 hobbit3 hobbit4 Each hobbit has 8 cores MPI mpicc -o mpi_outmpi_test.c -fopenmp OpenMP An Idea for a final project!!! cd ~/mpi program name: hybridpi.c
MPI is not installed yet on the hobbits, in the meanwhile: vdwarf5 vdwarf6 vdwarf7 vdwarf8
