PARDISO parallel processing when phase=33 ?

Hi.

I've known it is possible to use multi core parallel processing
when phase=33 solve part with multiple RHS.
Multiple cores seemed to be used.
But,through some experiments, I couldn't get the
speed-up when solve phase. Moreover, I saw the increasing
of run-time.

I need to increase speed-up in phase==33 solve phase.
It is urgent. Pleaselet me knowaboutany advices.

Hi,

First of all call PARDISO phase 33 with n rhs solve must solve quicker then nsequential call PARDISO phase 33 with 1 rhs. If is doesn't hold could you provide testcase to investigate it?
Nevertheless could you provide number of rhs and size of problem?
With best regards,
