[svn-r9104]

Purpose:
bug fix

Description:
1. The IF-block of skipping collective chunk IO tests when the number of
processes is greater than some number essentially skipped all parallel tests.
2.  John tested at copper with the number of processor = 64 and collective
     chunk IO tests passed, so we increase the number of precessor =24 to 64 for
    skipping the test.


Solution:
1. change the IF block flow so that it only skips collective chunk IO tests when
   the number of process is greater than 64.



Platforms tested:
copper(only change a bit of parallel test code, no needs to test on other platforms).
