------------ /cm/shared/uniol/modules/compiler ------------ PGI/12.10 PGI/15.10 PGI/16.10 (D)
➔ Modules with (D) at the end are marked as default modules. They are part of the standard cluster environment (called "hpc-uniol-env") and therefore always loaded. To load the module of your choice type e.g.
module load pgi/15.10
The commands for the available languages are
| Name | Description |
|---|---|
| pgcc | C compiler |
| pgCC | C++ compiler |
| pgfortran | Fortran compiler |
Advantages
- moderate/good performance for C, C++ and Fortran code
- OpenACC is implemented (extension for simple usage of accelearators like GPUs)
- GPU computing supported (e.g. CUDA)
- Fortran extension coarray implemented
Disadvantages
- slow compilation
- not free
- newest standards may missing
- OpenACC not a common standard
PGI Accelerator Suite addons
Within the PGI Accelerator Suite several tools and libraries for debugging, profiling and analyzing of program code are included:
- ACML (AMD Core Math Library)
- OpenMP/MPI debugger pgdbg
- OpenMP/MPI profiler pgprof
- MPICH
