Software Environment
HPC Software Stack
The HPC Software stack is made of the following software packages:
| Category | Software Package | Current Version |
|---|---|---|
| Compilers / Runtimes | CUDA Toolkit | 10.1 |
| GCC [System] | 4.8 | |
| GCC [Advance Toolchain 12.0] | 8.3 | |
| IBM XL C/C++ & Fortran | 16.1 | |
| PGI Accelerator | 2020 | |
| MPI Library | IBM Spectrum MPI | 10.3 |
| Scientific Libraries | IBM ESSL | 6.2 |
| IBM Parallel ESSL | 5.4 | |
| Performance Analysis | IBM Parallel Performance Toolkit | 2.4 |
IBM XL C/C++ is fully compatible with the C++ 11 standard.
IBM Spectrum MPI (based on Open MPI 2.0) has become the default choice for MPI library starting from Q4 2016. IBM Parallel Environment has therefore been discontinued.
