Compilers

Overview

Teton hosts several compiler collections. To utilize a compiler in any of these sets, one must utilize the module command to augment the environment to load the appropriate compiler set. To compile code that requires the utilization of the message passing interface (MPI), an MPI wrapper needs to be utilized.

Teton Compilers

Intel Compiler Collection

The Intel compilers are the preferred choice for compiling on Teton. This is because the compute nodes utilize Intel processors. Intel software often can optimize more for their own processing units better than other compilers, but that is not always the case or you may have specific reasons to utilize other compilers.

Intel Compiler Suite

Overview

Intel Parallel Studio Cluster Edition includes industry-leading C, C++ and Fortran compilers, performance libraries, standards-based parallel models, and performance-optimized Python. Build your software with a performance profiler, optimized vectorization, threading prototyping, and debugging tools for memory and threads. It Includes an MPI library, an MPI tuning and analysis tool, and an advanced cluster diagnostic system.

Module Load Command

Use the following module commands to enable access to the different Intel software components:

Compilers:

module load intel

Intel Math Kernel Library

module load intel-mkl

Intel MPI librariesL

module load intel-mpi

Intel debugging tools:

module load intel-tbb

GNU Compiler Collection

The GNU Compiler Collection (GCC) is a set of compilers that is open source and often found as part of any base Linux system for research computing. The following table shows the commands for compiling C, C++, and Fortran on Teton.

You can use the "module spider gcc" to see what versions of the compiler are available.

PGI Compilers

The PGI compilers are developed by the Portland Group and concentrate on providing full-featured compilers for several environments. PGI compilers also have extensions for additional programming practices such as OpenACC.

PGI Compiler Suite

Overview

PGI Compiler Suite includes PGI Fortran, C, and C++ compilers and tools for scientists and engineers. Features include V100 Tensor Core support, full C++17 language support, OpenACC print(), PCAST directives, LLVM 7.0, Turing support, and more. The PGI CUDA Fortran compiler now supports programming Tensor Cores in NVIDIA’s Volta V100 and Turing GPUs. Scientists using Fortran can take advantage of FP16 matrix operations accelerated by Tensor Cores.
