Branches: main
This change adds two new passes to the compiler. The first one,
implicit_parallelism, uses deep profiling feedback information, generated by
mdprof_feedback, to introduce parallel conjunctions where it could be
worthwhile. It deals with both independent and dependent parallelism.
The second new pass, distance_granularity, applies a transformation that
controls the granularity of parallelism for recursive procedures using the
distance metric.
This change also fixes a bug in mdprof_feedback regarding the construction of
the list of CSSs.
compiler/implicit_parallelism.m:
New module which uses the profiling feedback file generated by
mdprof_feedback to introduce parallel conjunction where it could be
useful.
compiler/distance_granularity.m:
New module. A program transformation that implements granularity control
of parallel execution using the distance metric.
compiler/dep_par_conj.m:
Moved find_shared_variables into the interface (needed for
implicit_parallelism.m).
compiler/goal_util.m:
Add two new predicates: flatten_conj and create_conj.
compiler/hhf.m:
Delete flatten_conj and use the one of goal_util instead.
compiler/hlds_pred.m:
Add a predicate to set the arity of a predicate (needed for
distance_granularity).
compiler/mercury_compile.m:
Add the calls to apply implicit parallelism and to control granularity
using the distance metric.
compiler/options:
Add implicit-parallelism, feedback-file and distance-granularity options.
compiler/pred_table.m:
Add a predicate to get the next pred_id available (needed for
distance_granularity).
compiler/prog_util.m:
Extend the predicate make_pred_name and the type new_pred_id for
creating a predicate name for distance_granularity.
compiler/transform_hlds.m:
Include implicit_parallelism and distance_granularity.
deep_profiler/mdprof_feedback.m:
Rename distribution to measure.
Add handling of dump_stages and dump_options.
Insert elements into the list of CSSs in the correct order.
deep_profiler/dump.m:
Add "all" option to dump everything out of the Deep.data file.
doc/user_guide.texi:
Add the following options: --distance-granularity, --implicit-parallelism and
--feedback-file.
tests/par_conj/Mercury.options:
tests/par_conj/dg_fib.{m,exp}:
tests/par_conj/dg_fib_func.{m,exp}:
Add two test cases for the distance_granularity module:dg_fib and
dg_fib_func. As things are, we do not check whether the granularity
control transformation using the distance metric is applied correctly or
not. We only check the output of these test cases.
