[comp.benchmarks] Computing first 1000 digits of PI

mark@mips.COM (Mark G. Johnson) (02/05/91)

In article <45469@mips.mips.COM>, I posted a 26-line C program that
computes PI = 4*arctan(1).  Here are some of the results folks
have measured (user CPU times with /bin/time).


DEC VAX-9000 (VMS 5.4)     0.39 seconds    mk@uta.fi
IBM RS/6000 model 540      1.15 seconds    rs0xeg@rohmhaas.com
IBM RS/6000 model 530      1.3  seconds    chriss@denali.ece.cmu.edu
IBM RS/6000 model 320      1.68 seconds    twood@UCSD.EDU
Cray Y/MP                  2.67 seconds    mccalpin@perelandra.cms.udel.edu
MIPS Magnum workstation    2.8  seconds    mark@mips.com
Sun SPARCstation 2         5.1  seconds    mawa@sun1.ruf.uni-freiburg.de
Sun SPARCstation 1+        9.5  seconds    mark@mips.com
