Is there any truth in this rumor? If so, it would be a pity. We really like
POWER2's performance. We were able to achieve 136 sustained, single-precision 
MFLOPS and 199 double-precision MFLOPS, which is more than 50% of the peak 266
MFLOPS on one POWER2 processor. 

This was achieved with a purely high-level, real-application  C code
(about 500 lines) without using and assembly or special library. We heard that
using Fortran could help even more. We know other people have been able to
achieve more than 100 sustained MFLOPS in CFD applications.

If POWER3 is out, what then?
