sysv in Scalapack?

Postby jamesssims » Sun May 28, 2017 1:03 am

I have gotten sysv to work in lapack and am now happy to see that there is an
sysy_rk. However, I don't see either one in Scalapack. Are one or both available
in ScaLapack? If not, any idea when they might be implemented?

Hello. Indeed, there is currently no SYSV in ScaLAPACK. For now, it is in the bucket list / wish list. Thanks for letting us know that this would be of interest for you. Julien.

( PS: for shared memory system, you might want to check out PLASMA, it does have a nice scalable SYSV solver based on Aasen's method. This might enables to tackle relatively large matrices on a single multicore node. )
