?potri and p?potri with MKL

Hi,

Is there a difference using ?potri and p?potri with MKL? At first, p?potri is a parallelised version of ?potri, but when I use the last one with MKL, all four CPU are running at the same time to find the inverse. So it looks like this routine is parallelised, correct?

Would it benefit processing time if I use p?potri instead of ?potri? Are there other methods ot speed up matrix inversion (I really need an inverse)?

Thanks and have a nice day!

Hi,
The ?potri is intended to computes the inverse matrixes on SMP systems but
- but p?potri - onfor distributed ( MPI but not SMP !!!).
