> Still, I'm looking for the routines CPOTRF/CPOTRS on IBM AIX. ESSL have routines named CPOF/CPOS, but I would by far prefer having the same call on all platforms: are there IBM vendor versions of the genuine LAPACK routines, or not ?
Hi, Pierre,
If you are concerned about performance issues AND portability then
LAPACK(reference implementation) + ATLAS(tuned blas) may be a good choice.
Which is, I suppose, is completelly portable.
Performance of LAPACK relies much on BLAS performance.
We are using this combination in our number cruncing program.
