Compiler for a parallel processor

A method for concurrently performing multiple computations in an associative processing unit (APU), the method comprising:

• having data in a donor matrix and in a left receiver matrix, wherein said matrices represent data stored in a first portion and a second portion of a memory array of said APU, respectively, and wherein each portion comprises cells arranged in rows and columns, wherein activating a first cell and a second cell located on a same location in different portions provides a result of a Boolean operation between said first and second cells;
• creating a Tartan matrix by computing an outer product between a first bit vector indicating selected rows and a second bit vector indicating selected columns, wherein said Tartan matrix represents data stored in a third portion of said memory array and wherein all cells having a value 1 in said Tartan matrix are selected cells;
• and
• concurrently activating all cells of said donor matrix, said left receiver matrix and said Tartan matrix and storing a result of Boolean operations therebetween in said left receiver matrix wherein a new value is obtained on cells located at a same row and a same column as said selected cells in said Tartan matrix and an original value remains on other cells.
