fine-grained-parallelism-tests
Testing fine grained parallelism with C++ and Boost.
Runtime fine grained parallelism: 895 ms
Runtime coarse grained parallelism: 1196 ms
Runtime single threaded: 1704 ms
N: 200000000 (calculations per thread)
M: 1 (number of repeated thread scheduling)
P: 2 (dual core)
FG.MT = Fine grained multithreading
CG.MT = Coarse grained multithreading
ST = Single threaded
Speedup: 1.90391 / 2
FG.MT needs 0.748328 (1/2) the time CG.MT needs.
FG.MT needs 0.525235 (1/2) the time ST needs.
FG.MT is 33.6313% faster than CG.MT.
FG.MT is 90.3911% faster than ST.
