qymeng 2008-07-21 16:11 Rev.: 41665

Added <zoltanIMBTol> tag in the input file for easy performance turning.
This can set the amount of imbalance Zoltan partitioning algorithm should deem acceptable.

for example:
<zoltanIMBTol> 1.05</zoltanIMBTol>
The value must be greater than 1.

Fixed a problem which caused Uintah crashing on Ranger with Zoltan RCB/RIB algorithm.
This is because MPI_Comm_dup and MPI_Comm_split does not work correctly in some MPI implementations(which Ranger use).
Fortunately, there is an undocumented parameter in Zoltan to avoid using these functions.
