Folks,
I've updated the Alpha MacLucasUNIX binaries at:
ftp://melanoma.cs.rmit.edu.au/pub/simonb/MLU-ALPHA.tar.gz
to include the "-assume accuracy_sensitive" option as discussed in
another message I sent to the mersenne list a few minutes ago. THE OLD
BINARIES WILL NOT PRODUCE CORRECT RESULTS!
I've tested this version against M380267 (the smallest result I had
lying around), and that residue was correct. It took 2590 seconds to
check that result, compared with 531978 on the DECsystem 5000/150 I
first got that result from!
The actual command line used to build these binaries was:
cc -DMERS_PACKAGE -DUSE_RUSAGE -fast -arch host -tune host -O4
-assume accuracy_sensitive -ifo -o MacLucasUNIX
MacLucasUNIX.c balance.c rw.c setup.c zero.c -lm
Using "-ifo" and listing all the .c files on the same line will do
inter-file optimisations. Whether or not anything was actually gained I
don't know. The new version is approx 1% slower than the old one, but
should produce correct results :-)
Simon.
