[svn-r9076] Purpose:
Better collective chunk IO test arrangements

Description:
collective chunk IO tests have been verified with the number of process greater than 24 and
the test is very slow with big number of process.

That may cause confusions to users who run collective chunk IO tests.

Solution:
To avoid possible confusions, A if-block will be used to check whether the number of process
is greater than 24. If yes, the collective chunk tests will be skipped and a message will be printed out.


Platforms tested:
linux 2.4
(too trivial to use h5committest)
