Just for kicks, while waiting for my phones to be hooked up at the new
address, I ran some heavy duty benchmarks to see if the systems
transported fine. i think they did arrive undamaged in the move, but
i ran pitest at the maximum rated precision.
apparently, this is not a /usr/bin/time issue, as i ran it again the
next day without it with the same IOT trap.
while this was running, it was approximately 80M or so into swap.
all other precisions seem to work fine up to and including MX=22 [~6
million digits].
this is a dual p2-333 system running -current from Sun Jul 25 23:51:16
CDT 1999 [yeah, i know, but i don't think that is the issue here].
512M RAM. and am using a tyan 1696dlua motherboard.
I will attach source code to this message. DO NOT change ANYTHING
except the MX value in pi4.f
i think the time returned by /usr/bin/time seems to be correct based
on my second run. the program only attempts file i/o once the run is
complete.
i AM NOT going to submit the half a gig core file, generate your own!
in the past day or so, i have tested EVERY MX between 14 and 22.
since this is a f77 program, it could be the fortran compiler, egcs,
or the OS itself causing this problem. the output file fort.4 remains
untouched and still contains the results of the previous test [MX=22].
