Information for new users to HPC resources




HECToR

To gain access to our resources on HECToR (project code e05) you will need to do the following:

1. Group leader should submit a proposal (two sides A4 max), which should state clearly: 1) To which theme it belongs, 2) The title of the sub-project, 3) Names of all investigators, 4) Name of the principle user i.e. one who needs an account and will submit the calcs on HECToR (note that this person can only be a principle user on one project), 5) The required AUs! NOT hours!, 6) The required disk space, 7) The code to be used (info on the scalibilty would also be useful), 8) The type of jobs (e.g. percentage of calculations using 512, 1024 CPUs etc)
2. If your sub-project proposal is successful, the group leader must email me (Scott.Woodley at ucl.ac.uk) confirming your Nationality (you should already be named as the principle user for a sub-project)
3. You must obtain our project password (e.g. Telephone me on 020 7679 0315 as this information should not be passed electronically)
4. Self register on the HECToR website at https://www.hector.ac.uk/safe, and click on 'here' near the bottom of the page.
5. As a new user, you may also find this document useful

I will then be able to approve your account and attach you to the corrrect budget within our consortium. Then you will be able to log onto your website account, from where you can check what resources you have access to and request a password for your unix account (from where you can run your jobs).






HPCx

To gain access to our resources on HPCx (project code e05) you will need to do the following:

1. The group leader must email me (Scott.Woodley at ucl.ac.uk) with such a request and must confirm your Nationality
2. You must obtain our project password (e.g. Telephone me on 020 7679 0315 as this information should not be passed electronically)
3. Self register on the HPCx website at http://www.hpcx.ac.uk/projects/new_users/. As a new user, you will also find it useful to read information on that page.

I will then be able to approve your account and attach you to the corrrect group within our consortium. Then you will be able to log onto your website account, from where you can request a password for your unix account (from where you can run your jobs) and check what resources you have access to.

Because we are a large consortium, we allocate both CPU time and Hard Disk space to each group. Thus, when you log onto your unix account, you will need to change from /hpcx/home/e05/e05/{your user name} (disk space here is allocated to e05 and is constrained to a minimum) to either /hpcx/home/e05/e05-***/{your user name} for homespace or /hpcx/work/e05/e05-***/{your user name} for workspace, where *** is either the first three or four letters of your group leaders surname. For more information please read this or my original communication on this matter.





CSAR

To gain access to our resources on CSAR (project code cse133) you will need to do the following:

1. The group leader must email me (Scott.Woodley at ucl.ac.uk) with such a request
2. You must obtain the access username and access password for your site (e.g. Telephone me on 020 7679 0315 as this information should not be passed electronically). Note that each institution has a different username and password, so if you are the first from your group I will need time to request new username and password to be created.
3. Self register on the CSAR website at http://www.csar.cfs.ac.uk/project_management/register.shtml for an account on Wren (front end and where you will be allocated disk space) and Newton (crunching machine and where you will be allocated CPU time). As a new user, you will also find it useful to read information on that page.

I will then be able to approve your accounts. Note that resources here are associated with individuals so I will need to know know to split up your groups allocated resources if you are not the only user from your group. PLEASE NOTE that our Hard disk space is more limited on CSAR (compared to HPCx) and is also charged as a function of time. However, there is scratch space on Newton but be careful as files that have not been recently touched will be deleted.
