Getting Started¶

An overview of HPC User Documentation
Project Accounts¶
There are three primary ways/projects to obtain access to Lawrencium:
- PI Computing Allowance (PCA): free 500K SUs annual renewable
- Condo: purchase and contribute Condo nodes to the Lawrencium cluster
- Recharge: charged at a minimal recharge rate roughly at $0.01/SU
User Accounts¶
You must have a user account to gain access to the Lawrencium cluster.
Logging in¶
You'll need to generate and enter a one-time password each time you log in.
Data Movement and Storage¶
To transfer data from other computers into - or out of - your various storage directories, you can use protocols and tools like SCP, STFP, FTPS, and Rsync. If you’re transferring lots of data, the web-based Globus Connect tool is typically your best choice: it can perform fast, reliable, unattended transfers.
The LRC supercluster’s dedicated Data Transfer Node is lrc-xfer.lbl.gov. For more information on getting your data onto and off of Lawrencium, please see Data Transfer.
Software Module Farm and Environment Modules¶
A lot of software packages and tools are already built as Software Module Farm and provided for your use. These software packages and tools can be loaded and unloaded via Environment Module commands. For details see Software Module Farm and Module Management.
Running Jobs¶
When you log into a cluster, you’ll land on one of several login nodes. Here you can edit scripts, compile programs etc. However, you should not be running any applications or tasks on the login nodes, which are shared with other cluster users. Instead, use the SLURM job scheduler to submit jobs that will be run on one or more of the cluster’s many compute nodes. For details see Slurm Overview and Example Scripts.
Open OnDemand¶
We provide interactive Apps, such as Jupyter notebooks, RStudio, MatLab, through the browser-based Open OnDemand service at https://lrc-ondemand.lbl.gov . Use your LRC username and PIN+one-time password(OTP).
