Get access to JADE HPC facilities
As agreed with EPSRC, the use of JADE is to be split approximately 50:30:20 between Machine/Deep Learning (ML), Molecular Dynamics (MD), and other applications, with up to 10% of the use being for research in non-EPSRC areas.
JADE is particularly intended for applications using up to 8 GPUs with a very high performance NVlink interconnect. It is not designed for MPI applications spanning multple compute nodes; for this purpose users should apply to use the GPU system which is part of the Cambridge Peta-5 GPU system.
PIs from other universities should apply for time through the twice-yearly EPSRC Tier 2 RAP (Resource Allocation Panel).
Time for Molecular Dynamics applications will be allocated via the BioSim HEC.
All UK academic users are eligible to apply for time for Other applications through the twice-yearly EPSRC Tier 2 RAP (Resource Allocation Panel). Pump-priming time will also be available; please contact Prof Mike Giles in the first instance.
To obtaining a user account you need:
This is a web account which will show you which projects you belong to, and the accounts which you have in them.
Before applying for a SAFE account, you should have an SSH key-pair ready, so you are ready to provide your public key as part of the SAFE registration process. Information on generating and using SSH keys is available here. Contact your local University RSE Support for any help.
Once you have your public SSH key ready, apply for your SAFE account here and providing all of the required information.
Once your account is approved, you receive an email giving your initial password. When you login for the first time you will be asked to change it to a new one.
Further details on the registration process are available here.
Use your SAFE account to apply for an account on JADE. Select the appropriate project from the drop-down list, enter the JADE project access which you have from the project PI or manager, and then click “Request”.
The approval process goes through several steps:
Once the account setup is complete, your SAFE account has full details on your new project account and you get a confirmation email. This process should not take more than 2 working days. If it takes more than that, check if the PI or project manager is aware that you have applied, and therefore your application needs their approval through the SAFE system.
Assuming your SAFE userid is xyz, and your project suffix is abc, then your project account username will be xyz-abc and you will login to JADE using the command
ssh -l xyz-abc jade.hartree.stfc.ac.uk
Note that some users may belong to more than one project, in which case they will have different account usernames for each project, and all of them will be listed on their SAFE web account.
Each project account will have a separate file structure, and separate quotas for GPU time, filestore and other system resources.
Note also that JADE has multiple front-end systems, and because of this some SSH software operating under stringent security settings might give warnings about possible man-in-the-middle attacks because of apparent changes in machine settings. This is a known issue and is being addressed, but in the meantime these warnings can be safely ignored.
Additionally, an optional step is applying for a Hartree ServiceNow account, which is a web account used for reporting any operational issues with JADE. An account can be obtained following here.
Note the guidance which explains that on first login, you will not have a password so you need to click on the link which says “reset your password here”.
Due to a problem with synchronising userids between ServiceNow and JADE, it is possible that ServiceNow may say that your email address is not recognised. If this happens, please send an email to firstname.lastname@example.org and ask them to add you to the ServiceNow database.
