1. Compile your OpenMP application | |||
g++ -fopenmp -o <output_file> <source_files> | |||
2. Compile your MPI application | |||
mpicxx -o <output_file> <source_files> | |||
3. Compiling your MPI + OpenMP application | |||
mpicxx -fopenmp -o <output_file> <source_files> | |||
4. Compile your MPI application with MPE support. This will generate a clog2 when you start the | |||
executable | |||
mpicxx -mpe=mpilog -o <output_file> <source_files> | |||
5. Execute a MPI program | |||
mpiexec -n <number of nodes> ./<executable> <input parameters> | |||
6. Login to one of the two 8 core Xeon processors | |||
ssh wn9 | |||
ssh wn10 | |||
7. Target a specific node with the MPI application. The file in the below command must have the syntax <IP | |||
address>:<number of MPI processes>. The IP address can be between 192.168.0.1 - 192.168.0.10. Computers from 192.168.0.1 | |||
to 192.168.0.8 have two cores and the two remaining have 8 cores each. | |||
