| - | ===== PGI 15.1 sur les systèmes Debian ===== | ||
| - | |||
| - | La version de PGI à utiliser sur les systèmes Debian est la 15.1. | ||
| - | |||
| - | ==== Environnement de travail ==== | ||
| - | |||
| - | Pour pouvoir utiliser PGI 15.1, il faut d' | ||
| - | |||
| - | <code bash> | ||

| - | Cette commande redéfinit les variables d' | ||
| - | |||
| - | Pour vérifier que cette étape s'est bien effectuée, on peut par exemple chercher si la commande pgfortran est reconnue et voir si elle concerne bien la version 15.1 : | ||

| - | <code bash> | ||
| - | e5-2670comp3: | ||

| - | ==== Options de compilation ==== | ||
| - | |||
| - | Parmi les options des compilateurs, | ||
| - | |||
| - | ^ Option ^ Description ^ | ||
| - | | -c | Generate intermediate object file but does not attempt to link | | ||
| - | | -g | Adds information for debugging to the object file and/or executable | | ||
| - | | -I < | ||
| - | | -L < | ||
| - | | -r8 | Promotes REALs from the default size of 4 bytes to 8 bytes | | ||
| - | | -i8 | Promotes INTEGERs from the default size of 4 bytes to 8 bytes | | ||
| - | | -O3 | Higher level of optimization than -O2 (the default optimization level) | | ||
| - | | -fast | Higher optimization level than -O3 | | ||
| - | | -Mipa | Tells the compiler to perform interprocedural analysis. Can be very time consuming toperform. This flag should also be used in both compilation and linking steps | | ||
| - | | -Mconcur | Enables autoparallelization. Additional options can be used with -Mconcur to provide morefine-grained control of autoparallelization | | ||
| - | | -Minfo | Instructs the compiler to report optimizations that are made | | ||
| - | | -Mneginfo | Instructs the compiler to report optimizations that are not made | | ||
| - | | -mp | Enables parallelization via OpenMP directives | | ||
