这个cluster (现在是两个node)的运行时间不太对(跨两个网段192.168.2.＊，192.168.4.＊)，单个节点比两个节点要快。
我不知是网络因素还是有其它的因素，测试行到的结果就是这个的结论。
我用同一个程序分别的在masterhost，execdhost和集群(分别用masterhost，execdhost作submithost)运行程序，得到的是单一节点比两个节点快。下面是我用shell写的脚本得到running time report：
#blrh=masterhost
#Rainbird=execdhost
#/root/one.sh==/root/sge-5.3/examples/jobs/one.sh
#/rooo/random_CDS.pl==/root/sge-5.3/examples/jobs/random_CDS.pl
