PDLARFB do not use PBLAS

Postby keitat » Thu Dec 16, 2010 12:55 pm

Hi,

I found some of ScaLAPACK routines such as PDLARFB are not fully taking advantage of PBLAS. In other words, they use only BLACS and BLAS to perform the compuation even though they can be done only with PBLAS calls. Is there any reason for doing so?

Thanks,

Keita

Hi Keita, no idea, did you try using PBLAS on your own? did you investigate? I have added your comment at:
