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 
importing random from random on engine(s)

__doc__ = """Tiny HTTP Proxy.

This module implements GET, HEAD, POST, PUT and DELETE methods
on BaseHTTPServer, and behaves as an HTTP proxy.  The CONNECT
method is also implemented experimentally, but has not been
tested yet.

Any help will be greatly appreciated.		SUZUKI Hisao
