A computer system is operable to identify subfields that differ in two data elements using a bit matrix compare function between a first matrix filled with pattern elements and a reference pattern.

Inclusive or bit matrix to compare multiple corresponding subfields

A computer system is operable to identify index elements in a vector index array that cannot be processed in parallel by calculating a complement modified bit matrix compare function between a first matrix filled with elements from the vector index array and a second matrix filled with the same elements from the vector index array.

Inclusive 'OR' bit matrix compare resolution of vector update conflict masks

Systems and methods start a process in an operating system. Additionally, a plurality of program units associated with the process are started. When a context shifting event occurs, each of the plurality of program units has their scheduling synchronized and their context set so that each thread processes the context shifting event. A further aspect of the system is that some program units may be executing on more than one multiple processor unit. In the operating system selects a multiple processor unit to host all of the program units, and migrates those program units that are not currently on the selected multiple processor unit to the selected multiple processor unit.
