I set the msglvl input of PARDISO to one so I get statistical information output to the screen, and when I run PARDISO with phase=33 (solve), I get something like this:
================ PARDISO: solving a complex nonsym. system ================
Summary PARDISO: ( solve to solve )
Time solve : 0.166810 s
Time total : 0.527333 s total - sum: 0.360523 s
The time solve is much much less than the "time total", and then the sum actually seems to be the difference. I couldn't find any information in the MKL documentation on this output. What exactly do these times represent? I'm asking because PARDISO isn't performing nearly as fast as I would want it to, and if I could get it to run 3x as fast (by limiting what I guess is overhead before and after the solve?), it would be a huge benefit. Thanks.
