The task is to speed up a summation by using parMap or parListChunk or better. It actually runs slower with parallelism code.
Edit: Facepalm.. I overlooked how to execute the application correctly.
Don't forget to add cores by
./myHaskellApp paramaters +RTS -N4 -sstderr
Where N4 is number of cores.
euler
is,5
may be much too small a chunk size. What if you try something more like 2000? (Although considering the smallitude of 15000,euler
is probably fairly expensive, in which case this wouldn't work)
