Data Type

REAL*8 (8-byte) words

Default Value

Read only

Description

This parameter returns the number of floating point operations saved by the optional algorithms specified with the IALGOR parameter. This is an approximate number only.

For Strassen, it is based on 1/8 the number of multiply and add operations being saved at each level of the recursion.

For complex matrix multiply, it is based on 1/4 the number of multiply and add operations being saved.

This is a gross savings value. The amount of additional work required by these algorithms for adding and subtracting is not subtracted from SAVOPS.

In order to accumulate this data, you must specify a value of the LOGTIM parameter greater than or equal to 3.
