ryaninhust / ipython_test
Created March 11, 2013 07:03 — forked from MOON-CLJ/ipython_test
在macbook pro 4核上的测试结果，python自带的map表现比起ipython 的map，list comprehensions都要好。但是有优化的multi_mcpi还是不错。
$ ipcluster start --n=4
print mcpi(100000000)
#print multi_mcpi_by_map(dview, 100000000) # 传递太耗时
#print multi_mcpi_by_list_comp(dview, 100000000)
#print multi_mcpi(dview, 100000000)
$ time py multi_mcpi.py
