Performance:
There are two performance-based test scripts: time_all_gfs_argv_init.sh and
time_all_gfs_hard_init.sh. Both scripts run the same tests, but initialize the
underlying GF fields in different ways (*argv* uses reed_sol_time_gf and *hard*
uses reed_sol_hard_time_gf.c).
You can run 'time_all_gfs_argv_init.sh' to time *all* possible GF
implementations on your computer. This script requires the 'gf_methods'
utility from GF-Complete to be in your PATH.
time_all_gfs_argv_init.sh was run on a MacBook Air and the distilled numbers
are given in ./PERF.txt. The results are sorted by encoding throughput. The
format of each entry reflects the arguments given to reed_sol_time_gf. For example,
the test run of
'Examples/reed_sol_time_gf 12 3 8 128 65536 -m SPLIT 8 4 -r SSE'
is recorded as this in PERF.txt:
