This is the serial (single core) version of the NAG Fortran library. Run the following module commands to load the environment for the Intel Compiler and the relevant NAG library<\/p>\n
\r\nmodule load compilers\/intel\/fortran\/12.0.5\r\nmodule load libs\/intel\/nag\/fortran_mark23_intel\r\n<\/pre>\nThis will set the following environment variable for easy access to the libraries, header files and example scripts:<\/p>\n
\r\nNAG_HOME_FLL6I23DC=\/opt\/gridware\/libs\/intel\/nag\/fll6i23dcl\r\n<\/pre>\nCompiling the example programs<\/h2>\n
The NAG library ships with example programs for every routine available. The directory<\/p>\n
\r\n$NAG_HOME_FLL6I23DC\/scripts\/\r\n<\/pre>\ncontains four scripts:<\/p>\n
\r\nnag_example_mkl\r\nnag_example_shar_mkl\r\nnag_example\r\nnag_example_shar\r\n<\/pre>\nwhich 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 differences between these scripts are shown below:<\/p>\n
\n
- nag_example_mkl<\/strong>, to link with the NAG static library libnag_mkl.a and the supplied MKL libraries<\/li>\n
- nag_example_shar_mkl<\/strong>, to link with the NAG shareable library libnag_mkl.so and the supplied MKL libraries<\/li>\n
- nag_example<\/strong>, to link with the NAG self-contained static library libnag_nag.a<\/li>\n
- nag_example_shar<\/strong>, to link with the NAG self-contained shareable library libnag_nag.so<\/li>\n<\/ul>\n
These can be used to inform you how to compile the NAG library according to your needs. For example, to compile,link and run the example for the routine c02aff using the NAG static library libnag_mkl.a and the NAG-supplied MKL libraries you would run<\/p>\n
\r\nnag_example_mkl c02aff\r\n<\/pre>\nThe output from this script is<\/p>\n

The output from running the example will be contained in the file c02affe.r<\/p>\n
