| Abstract: |
The pinhole simulation program is a computationally and memory intensive task. A conventional sequential approach would limit the size and complexity of such a problem when investigated in the framework of the SAO AXAF simulation system. A parallel version was developed instead, to enable distributed processing on a cluster of workstations. The program makes use of the Message Passing Interface (MPI) standard for parallel processing, implemented as an API (Application Programming Interface) to the Local Area Multicomputer (LAM) programming environment developed at the Ohio Supercomputer Center. |
