High Performance Computing Explorations using PETSc and SLEPc

Example code to explore high performance computing using PETSc and SLEPc. Here are a few resources to get you started with MPI clusters.

Portable, Extensible Toolkit for Scientific Computation

Scalable Library for Eigenvalue Problem Computations

Both libraries use MPI.

Running an MPI Program

Running an MPI Program in a LAN

Launching an Amazon EC2 MPI Cluster

Compiling the example

The makefile is primitive, and reflects my lack of knowlege and time.

Use make example1 to build the first example. Use example1 -help to see the options. I've been examining memory usage via

• ./example1 -n_row 200 -n_col 20000 -sparsity 0.03 -mat_type mpiaij
• ./example1 -n_row 200 -n_col 20000 -sparsity 0.03 -mat_type mpidense
