Performance Library Changes

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 subroutines available from Netlib at http://www.netlib.org. Oracle enhanced these public domain subroutines and bundled them as the Oracle Developer Studio Performance Library.

For this release, the following changes were made:

  • LAPACK in Oracle Developer Studio Performance Library is upgraded to version 3.5.0. All of the new features in LAPACK 3.5.0 are implemented in Oracle Developer Studio Performance Library, including the following:

    • Removal of optional arguments for Fortran 95 interfaces.

    • Base LAPACK routines updated to match LAPACK 3.5.0

  • New required minimum for the STACKSIZE environment variable set to 8 MBytes per thread.

    The Oracle Developer Studio Performance Library divides large data into blocks that fit within the hardware cache, and copies those blocks into the stack for better locality. Faster hardware means larger caches and thus larger blocks and larger stack sizes. To better accommodate current hardware, the required minimum stack size per thread is 8 Mbytes on all platforms.
