Recently DCU have purchased a share in facilities operated by ICHEC, the National High End Computing Centre. This share is available to all researchers in DCU and is separate from allocations granted through the standard ICHEC application process.

The way that this works is that each university who 'buys in' has priority rights to a part of the total computing power, (or partition of the available nodes), which are assigned preferentially by ICHEC to jobs from that institution. In effect, medium large jobs can now access the DCU condominium 'share' without researchers having to apply to ICHEC directly - e.g. by formal proposal for Class B say.

Requesting an ICHEC account

In order to request a new account the process is to mail https://iss.servicedesk.dcu.ie with the following details:

• Title:
• Full Name:
• Work email:
• Work Tel.:
• Preferred account username:

Please include confirmation that you have read and accept the ICHEC AUP http://www.ichec.ie/about_us/aup

Connecting to ICHEC

See details available on ICHEC website.
Note: You may need to use a proxy in order to SSH from DCU.

Submitting a job to the DCU 'condominium share'

Job submission to the DCU share is very straightforward - you just use the account string 'dcu01' as part of your submission script, so taking the sample from: http://www.ichec.ie/support/documentation/
