On Unix systems, for example, simply replace 'f77' or 'cc' with 'guidef77' or 'guidec' to get started. Guide uses standard OpenMP directives on all supported UNIX and NT SMP systems . For codes that are already parallel, included tools translate common parallel processing directives to portable OpenMP directives. There is no need to maintain separate serial and parallel versions, because OpenMP directives annotate the serial program. With Guide, you can exploit high-level parallelism that can lead to major performance improvements.
Guide contains selectable options to ensure high performance on various systems and data sets.
