The organisers would like to thank all the participants very much again for coming to the meeting on 4th June, we really hope you enjoyed the day. It was great to see such a large number of people, hearing about the interesting science that is being done with the Aquila HPC cluster and share ideas during both the formal and informal discussions.

In particular we would like to thank all talk- and poster presenters, the session chairs and the independent judges and everybody who participated in the discussions. We are very grateful to Prof Mike Giles for a very inspiring keynote lecture, James Davenport for the introduction in the morning and David Bird for guiding the discussion in the afternoon, and to everybody else who helped out during the day with catering, staffing the registration desk and making sure that everything went smoothly.

A photograph of all delegates can be found here: delegation photo.

We would like to congratulate once more Dr Eike Mueller, who won the prize for the best talk, and Adam Jackson, who won the prize for the best poster - well done!

Many of the presentations from the HPC Symposium are now available online, see the programme page for links to the presentations.

Also watch out for the news article which is soon to appear on the University webpage.

Given the success of yesterday's meeting and the lively discussion session in the afternoon, it would be great if we can build on the momentum to follow up from this. We would definitely like to hold another meeting next year, but if there is interest in this, we could also organise a shorter, informal discussion session sooner, i.e. within the next few months, with particular focus on the next generation Bath HPC system.

Also don't forget that there is a user mailing list on aquila (hpc-users@lists.bath.ac.uk) which can be used for general discussions. If you have any other ideas on how to follow on from the symposium or how to improve it next year, please email us on hpc-symposium@bath.ac.uk.

See you next year,

HPC Symposium, all day Tuesday, 4th June

  , , , ,

📥  High Performance Computing (HPC), Research

The University of Bath is holding its 2nd Symposium on High Performance Computing (HPC) which will take place on all day on Tuesday, 4th June (lunch included). This symposium is for any staff and students who use or are interested in using the HPC service.

If you would like to attend, please register before Friday 17th May by sending an email to hpc-symposium@bath.ac.uk and let us know of any special dietary requirements. See the Registration section below for more information.

The main aim of the symposium is to provide a forum for users of the University's HPC service, aka Aquila, and it will be an excellent opportunity to network and exchange ideas. Hopefully the experience and the people you meet will help you with your own research in the future.

If you are a researcher engaged in HPC themed scientific research and you wish to give a talk about your research or present a poster please submit an abstract by Friday 10th May 2013. Please see talks and posters section below for more information.

The following activities are planned for the day:

  • A keynote lecture by Prof. Mike Giles (University of Oxford), one of the UK's leading experts on using GPUs for Scientific Computing
  • Talks and posters by users of the HPC facility
  • A prize will be given for the best talk (iPad Mini) and the best poster (iPod Nano) presented
  • A discussion session on the future of HPC in Bath
  • A buffet lunch will be provided along with refreshments and lots of opportunities to network

The symposium will be held in 4 West room 1.2, further details can be found on the webpage:
http://go.bath.ac.uk/hpc-symposium

Feel free to print out and display the poster in your department, a .pdf version of the poster is available at http://go.bath.ac.uk/hpc-symposium-poster.

Registration
There is no registration fee, but we need to collect a list of attendees and know numbers in advance to organise catering. If you are interested in attending, please register before Friday 17th May by sending an email to hpc-symposium@bath.ac.uk and let us know if you have any special dietary requirements.

If you are planning to submit an abstract please could you indicate in your registration email whether your would like to give a talk or present a poster and could you include the title of your contribution.

Talks and posters
Contributions in the form of talks and posters are vital for the success of the symposium and there will be prizes for the best talk and poster. If you are currently using the University's HPC facility for your research, we strongly encourage you to share your experiences with others at the meeting. You can also present your research if you are not currently using the HPC facility, but are working on a computationally intensive problem which might benefit from using HPC.

The following topics will be covered (list not exhaustive)...

- HPC driven research in all disciplines
- Experiences with tools and libraries
- Parallel code development and scalability
- Algorithms
- Novel architectures: GPUs and Xeon Phi

Talk are scheduled to be 15 minutes (including questions).

If you plan to present a talk or poster, please submit your abstract in LaTeX or Microsoft Word format and send your .tex source file or the word template in an email to hpc-symposium@bath.ac.uk by the abstract submission deadline of Friday 10th May. The LaTeX and Word templates can be found on the http://go.bath.ac.uk/hpc-symposium website; please remember to rename the file with your username e.g. abstract_sac44.doc.

The best abstracts will be selected and a list of talks and posters will be announced on May 17th.

We are looking forward to seeing you on the 4th June,

the Scientific Organising Committee,

Dr Davide Tiana (Chemistry)
Dr Steven Chapman (Computing Services)
Dr Eike Mueller (Maths)

 

Scheduler maintenance -- update - 9/10/2012

  , , , , ,

📥  High Performance Computing (HPC)

Adaptive Computing have spent three 11-hour days assisting me with the installation and configuration of the new scheduling system on the Aquila HPC facility. During these days we have made a lot of progress and resolved several unforeseen issues. However there is some additional work remaining which largely involves systematically testing different queuing scenarios to ensure that the configuration is stable and is correctly scheduling the jobs.

Below is a summary of the work which has been accomplished over the last three days.

  • Moab v7.1.1 and Torque v4.1.1 have been installed on a dedicated server
  • the Aquila headnodes have been transformed into login/submit nodes
  • Torque v4.1.1 has been updated on all of the nodes and have been pointed to the new torque server
  • openMPI v1.6.1 has been recompiled to support the new version of torque
  • testing environment has been created to test the moab configuration
  • the workflow of moab configuration is largely completed

The majority of the moab configuration file reflects the outline to the scheduler I sent out in a previous email, we still have some of the more trivial elements to implement. The majority of the remaining works involves rigorously and systematically testing the various elements to the moab config file and some tuning; this will cover:

  • job preemption for development and course users
  • jobs which require license features
  • priority ordering
  • fairshare priority weighting
  • access control hacking
  • correct allocation of resources for types of jobs

This testing will be performed over the new few working days and during this time will have direct access to the support team and senior consultants from Adaptive Computing to assist me with any complications which arise. We anticipate that this work on the queue scheduler will be complete on Wednesday 10th October. Over the next few days I will be updating the HPC wiki pages with notes on how to use the new queuing system.

During this work a couple of the nodes have started to report issues. We currently have four nodes in a non-operational state. I'll be investigating these at a later date.

We thank you for your patience and are sorry for any inconvenience this extended maintenance and upgrade has caused.
