That's not unsurprising. The scipy solvers are terribly slow *and* the pysparse LU solver is quite fast, but uses a lot of memory.

I recently changed from the default solver (I believe this is SciPy) to PySparse by running my script with the --pysparse flag. A 3D diffusion problem that was solved in ~1 minute is now solved in ~5-10 seconds. I know PySparse is meant to be faster, but is it reasonable to expect an improvement of this magnitude or should I check some config/installation? _______________________________________________ fipy mailing list [email protected] http://www.ctcms.nist.gov/fipy [ NIST internal ONLY: https://email.nist.gov/mailman/listinfo/fipy ]
