This is mark 23 of the NAG Library. The following versions are available (see modulefiles below):<\/p>\n
Note that only the static versions of the NAG libraries may be used in this version. The compilation method that links against the NAG shared<\/em> libraries is not compatible with CSF3. See the example build scripts below.<\/p>\n We now recommend loading modulefiles within your jobscript so that you have a full record of how the job was run. See the example jobscript below for how to do this. Alternatively, you may load modulefiles on the login node and let the job inherit these settings<\/abbr>.<\/p>\n You should load the Intel compiler modulefile:<\/p>\n Then load one<\/em> of the following modulefiles:<\/p>\n This will set the following environment variables for easy access to the libraries, header files and example scripts:<\/p>\n The The NAG library ships with example programs for every routine available. The easiest way to compile the examples is to use the supplied scripts as details below. These also show you the full compilation commands which may help with compiling your own software.<\/p>\n We list the scripts available in each version of the NAG library and then show an example usage below.<\/p>\n The following scripts are available, which can be run directly from a jobscript:<\/p>\n which provide easy to use interfaces to compile, link and run each of these examples. This scripts<\/em> directory is added to your PATH environment variable for convenience.

The output from running the example will be contained in the file Overview This is mark 23 of the NAG Library. The following versions are available (see modulefiles below): CLL6I23DCL – C library for Intel compiler – serial version FLL6I23DCL – FORTRAN library for Intel compiler – serial version FSL6I23DCL – FORTRAN library for Intel compiler – parallel SMP version Note that only the static versions of the NAG libraries may be used in this version.
