Werner, N E

I describe my effort to convert a Fortran application that runs on a parallel supercomputer (Cray Y/MP) to run on a set of BBN TC2000 killer micros. I used both shared memory parallel processing options available at MPCI for the BBN TC2000, the Parallel Fortran Preprocessor (PFP) and the Uniform System extended Fortran compiler (US). I describe how I used the BBN Xtra programming tools for analysis and debugging during this conversion process. My ultimate goal for this hands on experiment was to gain insight into the type of tools that might be helpful for porting existing programs from a supercomputer environment to a killer micro environment. 5 refs., 9 figs.
