In response to a request we received from Jay Boisseau (boisseau@SDSC.EDU) in April, 1997, we provide here a broad overview of our early experiences porting a computational fluid dynamics code to the Cray T3E at the San Diego Supercomputer Center (SDSC).
Part I: | Background | [May 8, 1997] |

Part II: | Scalability Using the Portland Group HPF Compiler (The Good News) | [May 8, 1997] |
Parallel Programming
Method. Porting to the T3E.
