The various cases below correspond to runs of the ACL2 regression suite (distributed and workshop books) for ACL2 executables built on different platforms, as indicated. In each case below, the first number, User time in seconds, is by far the best one to use for comparisons (as opposed to System time or Elapsed time). Not shown here are tests of the ACL2 regression suite, all successful, on several other platforms: Lispworks 4.4.6 on 32-bit Ubuntu Linux, Allegro CL 6.2 and CMU Common Lisp 18d on Sun/Solaris (SunOS 5.9), and OpenMCL 1.1 snapshot r7591 on Darwin for Intel-based Mac.
All statistics shown below are for running
make regression. In
some cases the -j 6 was used (i.e., up to 6 parallel
jobs), so again, the first number in each case (marked with "u"),
User seconds, is more relevant than the rest. Each regression run was on a
2GHz AMD Opteron (tm) Processor 850 running Ubuntu Linux. One such machine was
used for the 32-bit OS runs; another for 64-bit OS runs.

At some point, perhaps "ACL2 Course Materials" will be a top-level link on the
ACL2 home page. For now, we provide some links.
