Major Section: SWITCHES-PARAMETERS-AND-MODES
This documentation topic relates to the experimental extension of ACL2 supporting parallel execution and proof; see parallelism.
General Forms: (set-waterfall-parallelism-hacks-enabled t) (set-waterfall-parallelism-hacks-enabled nil)
Some features (e.g., override-hints and clause-processors) of
serial ACL2 are by default not available in ACL2(p) with waterfall
parallelism enabled, because they offer a mechanism to modify state that
is unsound. To allow or (once again) disallow the use the these features in
ACL2(p), call set-waterfall-parallelism-hacks-enabled with argument t
or nil, respectively.
Set-waterfall-parallelism-hacks-enabled requires the use of a trust tag
(see defttag). One can call set-waterfall-parallelism-hacks-enabled!
instead, which will automatically install a trust tag named
:waterfall-parallelism-hacks.
See error-triples-and-parallelism for further related discussion.
