3. DESCRIPTION OF PROGRAM OR FUNCTION

GIP reads nuclide-organized cross-section libraries prepared for ANISN or DOT and prepares a group-organized library. This has the effect of making ANISN or DOT memory requirements almost independent of the number of energy groups.

4. METHOD OF SOLUTION

A simple multiple-pass sorting technique is used. Only sequential access is used. System routines are relied upon to provide blocking into efficient block sizes.
Data transmission and timing are provided through standard interface routines specified by RRD's de facto Computer Code Coordinating Committee.

5. RESTRICTIONS ON THE COMPLEXITY OF THE PROBLEM

GIP can provide acceptable efficiency if the total volume of data to be output is only a few times the available memory. Truly huge problems must use  random access code such as AXMIX.

6. TYPICAL RUNNING TIME

Running time is widely variable. A 76-group production problem with 48 input nuclides and 8 output mixtures required 0.19 minutes CPU time and 7.3 minutes total time on the IBM 360/91.
