The logically shared, distributed memory access (SHMEM) routines provide low-latency, high-bandwidth communication for use in highly parallelized scalable programs.
Applies to:


Grace is a “What you see is what you get” 2D plotting tool for the X Window System and Motif.
Applies to: ,


Cray LibSci is a collection of numerical routines tuned for performance on Cray XT, Cray XE, and Cray XK systems. Most users, on most codes, will find they obtain better performance by using calls to Cray LibSci routines in their applications instead of calls to public domain or user-written versions.
Applies to: ,


NumPy is the fundamental package for scientific computing with Python.
Applies to: , ,


SciPy is an open source library of algorithms and mathematical tools for the Python programming language that grew out of Travis Oliphant’s original collection of extension modules for Python which he released in 1999 under the name Multipack.

Porting Fortran code to GPUs with OpenACC

This page contains a video and slides that walk you through OLCF users Mike Zingale's and Adam Jacobs's experience with porting Fortran code to GPUs with OpenACC. The talk was given at the September 2015 OLCF User Group Conference Call.
Applies to:


Cray Performance Analysis Tools (CrayPAT) can be used to evaluate program execution performance on Cray systems.
Applies to: ,


The Grid Analysis and Display System (GrADS) is an interactive tools used for easy access, manipulation, and visualization of earth science data.
Applies to:


Cray Libsci accelerated BLAS (Basic Linear Algebra Subroutines) and LAPACK (Linear Algebra routines) routines enhance user application performance by generating and executing autotuned GPU kernels on Cray XK compute nodes. libsci_acc also provides a C API to allow pass-by-value semantics for input parameters, giving C programmers more productivity.
