[svn-r12117] Purpose:
Enhancing the optimiziation of collective IO per chunk
Description:
When the user does one of the following two things:
1. to do collective IO per chunk without using our optimization code
2. or the user passes the percent of number of process per chunk to be 0 when choosing
to do collective IO per chunk
It is not necessary that the library uses MPI-IO collective calls to do any optimization.
Solution:
Modify the code so that no MPI communication-involved analyses will be done for the above cases. Chunk addresses are obtained globally and IO modes are assigned to collective always.
Platforms tested:
h5committest
