There are two login nodes that can be used for compilation.

• E5-2620 v3 (Haswell)
• 2.40GHz, 12 cores (24 hyperthreads)
• 64 GB 1867 MHz
• 56 Gb/s FDR Infiniband

For performance reasons the following configuration has been chosen for compute nodes and login nodes.

• RedHat Enterprise 7.6

Filesystems

All nodes in the HTC mount the following file severs.

It is important to note the $HOME directories are shared with other clusters and configuration files may not be compatible. Please check through your .bashrc, .bash_profile and all other dotfiles if you encounter problems.

Compiler

GNU 4.8.5 compilers are available in your path when you login. Newer GNU 8.2.0 compilers are available as module environments.

Currently, HTC cluster does not support distributed parallel MPI jobs. Only shared memory parallel jobs are supported.
