[svn-r11067] Purpose:
Updating phase 2 work of collective IO
Description:
The current collective IO tests cannot test for number of processors bigger than
some values, this change will lift those restriction. However, the test may be slower.
Solution:
Platforms tested:
linux 2.4, AIX 5.1, Linux 2.4 IA64 and IRIX 6.5
(I haven't tested big number of processors with the restriction of the machine)
Misc. update:
