How to get it:
- sources at Netlib
- prebuilt for HP-UX 9.05 at Netlib
- Prebuilt for HPPA 2.0 (on SPP-UX) at HP's MLIB page
Verification:
- lots of self tests for all layers
- many failures with HP's prebuilt version
- partly due to BLACS initialisation problems
- less problems with own version
Comparison compiled version/HP-prebuilt:
- used optimization flags: +O3 +Odataprefetch +Onofltacc
- doesn't use LAPACK sources included in Scalapack
- performance:
- possible reasons:
- HP-Lapack is slower than the included standard lapack
- the new compiler versions of f90, cc produce slower code than
the old ones
- HP programmers have done a very good optimization job two years ago
