Maths research computing news

Huxley 616 in September 2020

Current status: July 24th: Maths server room cooling issues mean fewer active services, NextGen cluster upgrade now fully completed with 33 nodes & 832 processors available, all other active systems & services operating normally

Older news: August 18th: August 2023 update

New users please note: much of the documentation here was written at a time when users would mostly be using these research IT facilities whilst on a College campus. However, with the almost wholesale shift to off-campus remote working for most since March 2020 (and more recently, post-pandemic, a mixed hybrid working environment of both on-campus and remote working for many), this assumption is no longer valid and it is important to remember that for security reasons almost all internal systems at Imperial College are not directly accessible from the public Internet. If you have been given an account on a Maths system, please read this note for information on the various ways in which you can access Maths systems from anywhere in the world when you are off-campus.

You may also find these tips on getting the most from your remote broadband connection useful.

For a concise overview of the research computing facilities offered by the Mathematics Department. please visit the Research Computing Support page on the main Maths website. The sysnews website you are now reading is intended for those who already know about these facilities and want to know how to use them.

Continually updated, the pages you'll find here contain useful information about the Linux and UNIX-based IT services and facilities available to the research community in the Department of Mathematics. Admittedly, these pages are heavily biased towards these operating systems since most research is done on Linux, Macs or FreeBSD platforms but we would welcome suggestions on ways in which these pages can be expanded to include more support for Windows.

Getting support

Support is available most of the time including weekends, out of hours and during holidays simply by emailing Andy Thomas or by calling +44 7866 556626. More....
