C *==========================================================* |

|
|
C | This routine is called from the high-level wrapper |
| 19 |
|

C | after multi-process paralle processing has started but |
| 20 |
|
|
C | before multi-threaded parallelism. THe routine reads an |
| 21 |
|
|
C | an "execution environment" input parameter file holding |
| 22 |
|
|
C | information about the number of threads at run-time. |
