In this version, the rank==0 process writes *all* opening and closing |
| 41 |
XML tags. |
| 42 |
Individual process data is copied to a buffer before being written |
| 43 |
out. The routines are collectively called and will be called in the natural |
| 44 |
ordering i.e 0 to maxProcs-1. |
| 45 |
|
| 46 |
Notable Notables: |
| 47 |
the struct localIndexCache: stores local domain indices for faster reference |
