Latest Patents

One of Ren's latest patents is titled "Auto parallelization of zero-trip loops through the induction variable substitution." This patent describes a method and system for auto parallelization of zero-trip loops by substituting a nested basic linear induction variable. The innovation exploits a parallelizing compiler to enhance performance. The method includes using a max{0,N} variable for loop iterations when no information is known about the value of N, which is crucial for loops iterating from 1 to N. The process involves applying an induction variable substitution to nested loops, starting from the innermost loop to the outermost one. Additionally, it provides a removal of the max operator through a copy propagation pass of the IBM compiler, eliminating loop dependency on the induction variable and allowing for parallelization of the outermost loop.

Another significant patent by Ren is the "Framework for parallelizing general reduction." This patent outlines a method for providing parallel processing capabilities. It includes performing scalar and array privatization analysis via a compiler, checking whether an assignment statement is reducible, and recognizing reduction patterns through a pattern matching algorithm. The framework classifies the reduction type of each pattern and performs transformations and code generation accordingly.
