This section provides information about the available compilers on ALICE and SHARK.

Keep in mind that users do not have sudo permissions on the clusters.

If you need assistance with building software, please reach out to the support team for your cluster.

On ALICE or SHARK, you can select from a number of different compilers and different versions thereof:

ALICE

ALICE provides GNU and Intel compilers for compiling your own software

Within the EasyBuild framework used by ALICE, these compilers are combined with other libraries into common toolchains. The available toolchains are called foss (“free and open source software”) and intel.

Making use of the toolchain instead of only the compiler can be helpful if you need access to other libraries such as OpenMPI (for foss).

The toolchains are available in different version, e.g. for foss

[me@nodelogin02 ~]$ module -r avail ^foss

----------------------------- /cm/shared/easybuild/modules/all ------------------------------
   foss/2017a    foss/2018b    foss/2020a        fosscuda/2019a
   foss/2017b    foss/2019a    foss/2020b        fosscuda/2019b
   foss/2018a    foss/2019b    foss/2021a (D)    fosscuda/2020b (D)

Toolchains from foss/2021a and later always require loading the CUDA module separately.

Of course, you can still load only the GCC module that you need for compiling software, e.g.,

[me@nodelogin02 ~]$ module -r avail ^GCC

----------------------------- /cm/shared/easybuild/modules/all ------------------------------
   GCC/4.9.3-2.25      GCC/8.3.0             GCCcore/4.9.3    GCCcore/8.3.0
   GCC/5.4.0-2.26      GCC/8.3.0-2.32        GCCcore/5.4.0    GCCcore/9.3.0
   GCC/6.3.0-2.27      GCC/9.3.0             GCCcore/6.3.0    GCCcore/10.2.0
   GCC/6.4.0-2.28      GCC/10.2.0            GCCcore/6.4.0    GCCcore/10.3.0
   GCC/7.3.0-2.30      GCC/10.3.0            GCCcore/7.3.0    GCCcore/11.2.0 (D)
   GCC/8.2.0-2.31.1    GCC/11.2.0     (D)    GCCcore/8.2.0

If you need to build your program with MPI support, you can load an available OpenMPI module

[me@nodelogin02 ~]$ module -r avail ^OpenMPI

------------------------------ /cm/shared/easybuild/modules/all -------------------------------
   OpenMPI/2.0.2-GCC-6.3.0-2.27      OpenMPI/3.1.4-gcccuda-2019b
   OpenMPI/2.1.1-GCC-6.4.0-2.28      OpenMPI/4.0.1-GCC-8.3.0-2.32
   OpenMPI/2.1.2-GCC-6.4.0-2.28      OpenMPI/4.0.3-GCC-9.3.0      (D)
   OpenMPI/3.1.1-GCC-7.3.0-2.30      OpenMPI/4.0.5-GCC-10.2.0
   OpenMPI/3.1.3-GCC-8.2.0-2.31.1    OpenMPI/4.0.5-gcccuda-2020b
   OpenMPI/3.1.3-gcccuda-2019a       OpenMPI/4.1.1-GCC-10.3.0
   OpenMPI/3.1.4-GCC-8.3.0

If you then need another module, you can load the module matching the version of GCC that you want to use.

The Intel toolchain can be access using the intel module, e.g.,

SHARK

SHARK provides GNU compiles for compiling your software.

You can find them in the system branch of the module tree:

If you need compile your software with MPI support, you need to load the corresponding module of MPI:

This is a handy reference table for showing you which MPI compiler matches which language

Language	C	C++	Fortran77	Fortran90	Fortran95

Language	C	C++	Fortran77	Fortran90	Fortran95
Command	mpicc	mpiCC	mpif77	mpif90	mpif95

You can find a basic example for compiling a program with MPI support and run it on the cluster in the Tutorials section: Your first MPI job
