The Oracle Developer Studio Performance Library is a set of optimized, high-speed mathematical subroutines for solving linear algebra and other numerically intensive problems. Oracle Developer Studio Performance Library is based on a collection of public domain applications available from Netlib at http://www.netlib.org. These public domain applications have been enhanced and bundled together as the Oracle Developer Studio Performance Library.
Each subroutine in the Oracle Developer Studio Performance Library performs the same operation and has the same interface as the standard library versions, but is generally much faster and more accurate and can be used in a multiprocessing environment.
See the Oracle Developer Studio 12.6: Performance Library User’s Guide for details.
