The issue I mentioned that sometimes the old version is faster has to do with a readin problem (status "get"). If status is showing 95% in LU, that's not the problem. If the old version is any faster in this case, it is probably random slop or compile options, or maybe a side effect of differences in time step control. Since you are getting 95% in LU .. what is "density"? That's where node ordering comes in. For a passive circuit, it is normal that most of the time is in LU. _______________________________________________ Help-gnucap mailing list [email protected] https://lists.gnu.org/mailman/listinfo/help-gnucap
