5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

The array sizes can be increased fairly easily. Currently it calculates data in up to 42 energy groups.

[ top ]

6. TYPICAL RUNNING TIME: 29 minutes (ICL 470) to produce data in 30 energy groups.

NEA-0481/02

NEA-DB ran the test case included in this package on a DEC VAX 11/780 computer in 11 minutes of CPU time.
