Performance monitoring (for the layered solver)
This logs simple statistics available for the layered solver.
event perfs (i += 1) {
static FILE * fp = fopen ("perfs", "w");
if (i == 0)
fprintf (fp,
"t dt mgp.i mgp.nrelax grid->tn perf.t perf.speed npe perf.ispeed\n");
static double start = 0.;
if (i > 10 && perf.t - start < 1.) return 0;
fprintf (fp, "%g %g %d %d %ld %g %g %d %g\n",
t, dt,
#if NH
mgp.i, mgp.nrelax,
#elif IMPLICIT_H
mgH.i, mgH.nrelax,
#else
0, 0,
#endif
grid->tn*nl, perf.t, perf.speed*nl, npe(), perf.ispeed*nl);
fflush (fp);
start = perf.t;
}If we have a display (and gnuplot works), a graph of the statistics is displayed and updated at regular intervals (10 seconds as defined in [perfs.plot]()).
event perf_plot (i = 10) {
if (getenv ("DISPLAY"))
popen ("gnuplot -e 'set term x11 noraise title perfs' "
"$BASILISK/layered/perfs.plot 2> /dev/null "
"& read dummy; kill $! 2> /dev/null", "w");
