Walk-In Workshops

Overview of TCHPC

The Trinity Centre for High Performance Computing (TCHPC) provides Trinity researchers from all disciplines with the following services:

  • advanced computing (Linux and HPC)
  • data management
  • visualisation
  • and software development facilities and expertise

Walk-In Workshops

TCHPC runs monthly Walk-In Workshops, which are open sessions for people to come in and ask questions and get help in an informal setting.

Please note that these are not formal training sessions - you can drop in at any time during the workshop with a question for 5 minutes and then leave (hopefully happy!).

TCHPC staff members will be on hand to discuss any problems with you.

Light refreshments of tea/coffee/biscuits will be provided.

Venue and Date of the Workshops

We generally run the workshops on the first Friday of each month, in our training lab (Room 2.12 in the Lloyd Building).

However, this is subject to change to please check the news section for the current time and venue each month.

Focus of workshops

The workshops will be focused primarily on questions regarding TCHPC systems in particular and Linux in general.

See below for examples of questions people might ask.

Audience

We would welcome people who are users on our systems already with questions about how the clusters work, or people who may have issues in general with Linux.

Please let your colleagues know about the Workshops, as they may have some issue which turns out to be relevant for you.
