GNU Compilers
Fortran, C and C++ compilers produced by the GNU Project.
Availability and Restrictions
Versions
The GNU Compiler Collection (GCC) are available on all our clusters. These are the versions currently available:
Programming
Boost
Boost is a set of C++ libraries that provide helpful data structures and numerous support functions in a wide range of aspects of programming, such as, image processing, gpu programming, concurrent programming, along with many algorithms. Boost is portable and performs well on a wide variety of platforms.
Compilation Guide
As a general recommendation, we suggest selecting the newest compilers available for a new project. For repeatability, you may not want to change compilers in the middle of an experiment.
Pitzer Compilers
OpenACC
OpenACC is a standard for parallel programming on accelerators, such as Nvidia GPUs and Intel Phi. It consists primarily of a set of compiler directives for executing code on the accelerator, in C and Fortran. OpenACC is currently only supported by the PGI compilers installed on OSC systems.
OpenMP
OpenMP is a standard for parallel programming on shared-memory systems, including multicore systems. It consists primarily of a set of compiler directives for sharing work among multiple threads. OpenMP is supported by all the Fortran, C, and C++ compilers installed on OSC systems.
Python
Python is a high-level, multi-paradigm programming language that is both easy to learn and useful in a wide variety of applications. Python has a large standard library as well as a large number of third-party extensions, most of which are completely free and open source.
PGI Compilers
Fortran, C, and C++ compilers provided by the Portland Group.
MVAPICH2
MVAPICH2 is a standard library for performing parallel processing using a distributed-memory model.
Intel Compilers
The Intel compilers for both C/C++ and FORTRAN.
Availability and Restrictions
Old Intel compiler licenses on Pitzer and for state-wide access with versions 19.1.3 and earlier will no longer be available from March 31, 2025. We are currently investigating options to mitigate the impact. More details will be posted soon, so please stay tuned. If you have any concerns, please contact OSC Help.
Versions
The versions currently available at OSC are:
CUDA
CUDA™ (Compute Unified Device Architecture) is a parallel computing platform and programming model developed by Nvidia that enables dramatic increases in computing performance by harnessing the power of the graphics processing unit (GPU).
