NAG SMP Math Library
The NAG SMP Library is a library of Fortran 77 routines optimised for use on Symmetric Multi-processor (SMP) machines. It contains all the routines contained in the NAG Fortran Library.
The subroutine interfaces of the SMP version are identical to those of the NAG Fortran library; this makes porting from NAG Fortran library to NAG SMP library trivial -- just recompile and relink your code to the SMP Library to take advantage of the capabilities of the architecture IBM SP Power3. The version on IBM SP is double precision.
Note: In current release, a much larger number of routines have been specially tuned to maximize their performance on shared memory parallel systems. For list of tuned routines, see NAG SMP Library Release 2 News
How to use
% module load nag_smp % xlf_r -qsmp=omp -qnosave $NAG_SMP ...
Example Programs
NAG SMP example programs can be accessed by the command nagsmpexample. For example,
% nagsmpexample c06eaf
It will copy the example program and its data into the files c06eafe.f and c06eafe.d in the current directory and then compile, link, and execute the example and write its results to stdout. Further usage details may be obtained by using the command nagsmpexample without arguments.
