Cray J90
| Cray UNICOS machines have a hardware
performance monitor (hpm), which gives the number of floating point operations
per CPU second (FLOPS) performed by a given process. All routines were compiled with: cft77 -ez

COMMENT: Total work is scaled with the number of processors. The ZEUS-3D
EDITOR preprocessor inserted parallelization directives. Fortran
routines compiled with cf77 -Zp -Wf"-ez". Light system load. The
speedup is the average concurrency reported by the job accounting
utility "ja".
