- I wish Allen Akin and Michael Jones had taken the time to investigate the
- direction PLB is taking before making comments. Rich Thomson is equally
- to blame.
-
- 1. Yes, the PLB was based on a purely PHIGS model and yes, SGI does not
- care for this model. BUT, there is now two sets of numbers, the
- PLB literal and the PLB optimized where literal is the PHIGS model
- and optimized is whatever you want it to be as long as the picture
- is correct.
-
- 2. A good port of PLB takes time (much longer than I or anyone else would
- want). The chicken and egg syndrome occurs when you as a consumer want
- to use PLB as a required benchmark but its not ready and then the vendors
- see that no one is asking for PLB numbers so they don't spend money to
- work on the port.
-
- 3. In a few days (weeks), the reference port, PLB documentation and test
- data will be available for anonymous ftp. Watch this space and
- comp.benchmarks for more information.
-
- P.S. Allen and Micheal should talk to Keith Seto as should anyone else
- interested in SGI's work on PLB. Keith's number is 415-390-3321.
