• IBM Compilers for pSeries. This is a 2001 presentation at Scicomp describing many important compiler options and summarizing the operation of the different components of the compilers on codes.
• The T. J. Watson Research Center is the source of much of the information and many of the examples in this document.
• IBM SP Documentation: IBM XL Fortran User's Guide, IBM XL Fortran Language Reference, C/C++ Compiler and Language References.
• Power3 Introduction and Tuning Guide, SG24-5155-00. This is a highly detailed description of the POWER3 performance characteristics.
• IBM has a very useful manual entitled, "Optimization and Tuning Guide for Fortran, C, and C++", SC09-1705-01. Unfortunately there are two drawbacks to it: the most recent edition is dated June, 1996, so it is somewhat out of date, and it is not available on-line. A paper copy may be ordered from LINKWeb Order Support.
• The ascii file /usr/lpp/xlf/DOC/README.xlf contains the release notes for the current version of the Fortran compiler.
