Application Details
- Description: OpenUH is an Open64 based open source OpenACC compiler supporting C and FORTRAN, developed by HPCTools group from University of Houston.
- Version: 3.1.0
- Module: openuh/3.1.0
- Licence: Github, open source
Usage
Important: This is a module installed to allow testing of the GPU Nodes, if you need this as a production module contact the Viper Team at Topdesk .
Language highlights
- C compatible with gcc
- C++ compatible g++
- Fortran90 with Fortran95 extensions
Compiler Optimizations
At the -O2 and -O3 optimization levels the compilers will use the IA-64 software pipe-lining instructions. At the -O3 level a more powerful data dependence analysis will be performed.
Scalar Optimizations
A partial list of optimizations performed include:
- Code motion
- Constant propagation
- Dead code elimination
- Expression simplification
- Common sub expression elimination
- Strength reduction
Module
[username@login01 ~]$ module add openuh/3.1.0
