在linux运行网格模拟器

zyh_nust

我 现在 在装 o p to r si m ,可是却遇到这样的情况,想问问 您能否告诉我如何解决,我实在是一筹莫展了
起码我想你对lin x 比我熟悉很多 .
我装好了j d k 和an t ,在/usr/local/optorsim/放了o p to r si m ,然后感觉没有问题了,可是输入这个出现如下:
是不是安装的问题亚
[root@zyh edg_testbed]# OptorSim.sh infn_to_cern_ave.numbers
============= O P T O R S I M =============

Exception in thread "main" java.lang.NullPointerException

有的时候
[root@zyh /]# OptorSim.sh parameters.conf
============= O P T O R S I M =============

OptorSimMain> using default parameters file examples/parameters.conf

OptorSimParams> usage: Optor.csh/sh/bat [parameters file]
Please use a parameters file that exists or leave blank to use the default one.


能否帮我看下是那方面的问题,已经困绕了好久 ,谢谢

这个软件的名字中间怎么这么多空格啊？o p to r si m

是不是类似netsim一类的软件？楼主详细介绍一下吧
