National e-Science Centre SRIF-3 Resources for Edinburgh University; An HPC Technical Briefing Seminar. e-Science Institute 09th May 2006 Martyn Guest and Christine Kitchen from the Daresbury Lab distributed computing (DISCO) group presented a day long seminar covering many aspects of the performance of large computing clusters which need to be taken into account during procurement. The event was attended by about 20 people from various schools in CSE and CMVM. The event was very informal with many questions. The goal was for Edinburgh staff to benefit from the experience of the DISCO group in order to help us in future procurements. Peter Clarke
