- I should say something about this.
-
- Some time ago I was talking to certain members of SPEC, and we were going to
- run the entire suite thru a Y-MP with a hardware performance monitor.
- Unfortunately, work commitments and porting time weren't a good match.
- Several of the code are Cray codes, it's the other codes which aren't which
- require a little work. The relation isn't 1:1; it isn't known.
- This is work which should be done.
-
- One of these days I'll have some time to get back to the FAQ......
