Efforts have been made to ensure that the versions of the available software are identical on both clusters but, at times, there will be differences.
Base Modules
| Module | Description |
|---|---|
| cmake/3.20.4 | Portable Build Process Manager – cmake.org This tool is useful if you want to be able to build your software on Linux, Mac or Windows. |
| gcc/8.4.0 | The GNU GCC suite of C, C++ and Fortran compilers – gcc.gnu.org |
| gcc/10.2.0 (D) | The GNU GCC suite of C, C++ and Fortran compilers – gcc.gnu.org |
| git/2.32.0 (D) | Git – Distributed Version Control System – git-scm.com |
| intel/2021.2 | The Intel Compiler suite of C, C++ and Fortran compilers – software.intel.com |
| matlab/r2020a | Matlab R2020a – uk.mathworks.com |
| python/3.8.5 | Python v3.8.5 – python.org |
| python/3.9.5 (D) | Python v3.9.5 – python.org |
In general, the Intel compilers will give you slightly better performance (5-10% faster). However, the GNU suite of compilers tend to insist your software more strictly adheres to relevant language standards. This means if you want to ensure your software will compile on any other Linux platform then choose the GNU compilers.
During development, it is suggested to use the GNU compilers as they will identify more potential issues with your software. In production however, if you want unltimate performance, then the Intel compilers will likely produce quicker run-times.
Compiler based Modules
These modules all require one of the compiler suites to be already loaded. The compiler suites that are compatible are listed in the table below.
| Module | Compatible Compilers | Description |
|---|---|---|
| boost/1.76.0 | GCC (all) Intel v16 (enhpc) | Boost C++ libraries – www.boost.org |
| mvapich2/2.3.6 | GCC (all) Intel (all) | The MPICH implementation of MPI – mvapich.cse.ohio-state.edu |
| openblas/0.3.12 | GCC (all) Intel (all) | The BLAS libraries – www.openblas.net |
| openmpi/4.1.1 | GCC (all) Intel (all) | The OpenMPI implementation of MPI – www.open-mpi.org |
| valgrind/3.17.0 | GCC (all) Intel v16 (enhpc) | Debugging and profiling tools – valgrind.org |
MPI based Modules
These modules all require a compiler suite and an MPI library to already be loaded.
