f0c345841c Added a factory version of par::mapi, which avoids the need for share_arc, and copies arcs between tasks better. 2012-05-30 17:39:53 -07:00

f05040f17a Use std::deque now that the bugs are fixed. Also, avoid a few copies. 2012-05-30 17:39:53 -07:00

f49b891ce5 Include capture clauses when generating metadata. 
This may fix the bug that's blocking Issue #2441.

aa2efc05ea Adding shared_arc to hide some of the tedium of sharing an arc between tasks. 
Also added some asserts and logging to trans.

Modified graph500 to use the shared_arc, but this unfortunately doesn't work due to #2444.

5a4e2ae706 More unsafe pointers to share immutable structures between tasks. This version has a 2.8 to 3x speedup! 2012-05-22 15:31:39 -07:00

77f6099606 Using unsafe pointers to views to try to reduce some vector copy and allocation time. Doesn't seem to have made much difference. 2012-05-22 15:31:39 -07:00

ea889742d7 Using unsafe pointers to share closures. 
This prevents the tons of copying problems we were having before, which means we only have a 5x slowdown now.

a785f3fc95 Adding a module with parallel vector operations. 
This should go in libstd, but currently resolve bugs make this not

c902eafa14 Convert old-style for loops to new-style 
Most could use the each method, but because of the hack used to
disambiguate old- and new-style loops, some had to use vec::each.

(This hack will go away soon.)

Issue #1619

 - Split fs between core::path and core::os.
