Class Final
reports & Final The project is to describe and demonstrate what you have learned in class. The idea is to take an application and implement it on a parallel computer. Describe what the application is and why this is of importance. You should describe the parallel implementation, look at the performance, perhaps compare it to another implementation if possible. You should write this up in a report, 1015 pages, and in class you will have 20 minutes to make a presentation. Here
are some ideas for projects: o

and additional
projects. Additional Reading Materials Message Passing
Systems
Several implementations of the
MPI standard are available today. The most widely used open source MPI
implementations are Open MPI and MPICH.
