Abstract
One embodiment of the present invention sets forth a technique for performing RAID-6 computations using simple arithmetic functions and two-dimensional table lookup operations. A set of threads within a multi-threaded processor are assigned to perform RAID-6 computations in parallel on a stripe of RAID-6 data. A set of lookup tables are stored within the multi-threaded processor for access by the threads in performing the RAID-6 computations. During normal operation of a related RAID-6 disk array, RAID-6 computations may be performed by the threads using a small set of simple arithmetic operations and a set of lookup operations to the lookup tables. Greater computational efficiency is gained by reducing the RAID-6 computations to simple operations that are performed efficiently on a multi-threaded processor, such as a graphics processing unit.
