How to access the HPC

RStudio Server

RStudio in your web browser.

Secure Shell (SSH)

Use a SSH client (such as PuTTY for Windows) to log in to hpc.niasra.uow.edu.au and then use SSH from there to connect to a computing node, for example:
ssh niasra-node1

You can then run the interactive R interpreter with this command:
R

Or run a script file (for example, myscript.r) in non-interactive mode with this command:
Rscript myscript.r

The Linux utilities screen or tmux can be used to keep your programs running after you close the SSH connection.

SSH key fingerprints:
RSA 2048 SHA256:cp8CcZejIDw+yxiUBlbLWZjNF6tKwYoKBw/VuwRI9nE
ECDSA 256 SHA256:YEJMF7iarqjOD/28HcMcWZlCoUhEoDyKqaB3eYyQIHw
ED25519 256 SHA256:VW3O/PV4SBQC4xAvWoon8u1ZeTxmtA/V8/KJkoERolU

Secure File Transfer (SFTP) or Secure Copy (SCP)

Link: Instructions for SFTP.

Remember to always keep a backup of important code and data on your own computer!

GPU

Node3 contains a Nvidia Titan 6GB GPU, Node4 contains a  Nvidia Tesla V100 32GB GPU, Node5 and 6 contains a Nvidia A100 80GB GPU.

You might be able to use the GPU without any changes to your R code by automatically intercepting certain BLAS routines with NVBLAS. Log in to niasra-node3 or niasra-node4 by SSH and run R with this command:
LD_PRELOAD=/usr/local/cuda/lib64/libnvblas.so NVBLAS_CONFIG_FILE=/etc/nvblas.conf R
or
LD_PRELOAD=/usr/local/cuda/lib64/libnvblas.so NVBLAS_CONFIG_FILE=/etc/nvblas.conf Rscript myscript.r
