Balena maintenance - 2nd February 2017

  , , , ,

📥  High Performance Computing (HPC)

During Inter-Semester break, on Thursday 2 February between 09:00 and 13:00, we will be placing the cluster into maintenance mode whilst we perform failover tests between the pair of master nodes and BeeGFS node couplets.

These tests will ensure that pairs of master nodes and BeeGFS node couplets are in good working order should an unexpected system issue occur that triggers a system failover.

While the system failovers are being tested, all users will be able to access data from /home and /beegfs, but you may notice a momentary freeze while the storage areas are transferred between the failover pairs. All compute nodes will be placed into a scheduler reservation to prevent any workloads from running while these tests are carried out.

Sorry for the short notice of this announcement, I hope this will not cause too much disruption for anyone.

Dr Gavin Shaddick, of the University of Bath’s Department of Mathematical Sciences and Deputy Director of the Bath Institute for Mathematical Innovation, has been leading an international research team, which includes the WHO, and have used the University of Bath's High Performance Computing (HPC) system, Balena, to investigate global air pollution.

The results show that nine out of ten people (92 per cent) on Earth live in places where air pollution is higher than acceptable limits – even when they are outside.

Balena Maintenance - 8th to 12th August 2016

  , ,

📥  High Performance Computing (HPC)

The maintenance work will begin on Monday 8th August and is expected to take up to a week to complete. During this maintenance window there will be no access to the Balena system and all queued jobs will need to be cleared from the scheduler.

The majority of this work will be performed by ClusterVision. We are anticipating needing a full week to give ClusterVision and ourselves enough time to complete these maintenance tasks. We shall open up access once all disruptive tasks have been completed.

Below is a list of some of the maintenance work which will be taking place:

  • Upgrading the SLURM scheduler, security patching and enabling new features
  • Testing SLURM's node power management
  • Enabling global file locking on the BeeGFS scratch partition
  • ClusterVision will also be configuring new system monitoring tools

HPC for researchers by Tobias Brewer

📥  High Performance Computing (HPC), Research

The annual symposium at Bath brings together people from across the University to discuss how they use High Performance Computing (HPC) in their research. This year, the event included talks from several departments as well as keynote speakers from Intel and Cardiff University. People with projects from many diverse research areas attended and presented their work on topics such as data sharing in biology, computational screening of inorganic materials and topological optimization. All of these projects benefit hugely from HPC.

My PhD research centres around the efficient simulation of rare events and determining the probability of their occurrence. How likely is it that a tsunami will strike this coastal city? What was the probability of this genetic mutation? Could this village be destroyed by a lava flow? To answer questions like these requires computer codes that concurrently simulate a very large number of sophisticated systems. The C++ program's that perform these simulations take a ludicrously long time to run. The University's HPC computing system, Balena, allows these computations to be sped up dramatically, often by a factor of more than 20. This makes it simpler to consider more sophisticated systems and to perform analysis of much rarer events. A simulation that would have otherwise taken a month to run now takes less than two days.

Furthermore, with Balena facilitating the execution of several codes simultaneously, researchers can obtain results from many different simulations at the same time. Balena has a huge amount of software and hardware available for researchers to employ: various compilers, a SLURM scheduler and MPI libraries for parallelizing code. Of particular use to my research are the Allinea profiling tools which make it easy to identify bottlenecks and bugs and to pinpoint memory leaks. The system also enables the use of accelerator cards, such as the Intel Xeon Phi's, which can reduce computation time even further. I'd encourage any researcher at Bath to utilise Balena for its wide range of computational tools and for the considerable amount of time that it can save you in your research.

Attendees of the 5th HPC Symposium

We would like to thank everyone who joined us at the 5th Annual Bath HPC Symposium yesterday. Following the trend from previous years, the event was a great success for the University.

This year represented the fifth symposium and the event was attended by over 50 participants from within the university, collaborators, as well as external partners including Intel. The schedule for the day included contributions from across the University: physics, maths, chemistry, biology; mech-eng, elec-eng and chem-eng; management and architecture. These contributions showcased the sheer variety of innovative HPC work being done across the University, covering including molecular dynamics and quantum-chemical simulations through to high level finite-element methods to solve engineering problems. The Symposium provided a great opportunity for networking and for learning about new developments in hardware, software and applications.

We would like to say a big thankyou to the contributors, attendees, keynote speakers, session chairs and ground crew, who together made this meeting a day to remember.

Also, we would like to congratulate our two prize winners, Tobias Brewer and Will Saunders, once again for their outstanding poster presentation and contributed talk.

Best wishes,
Steven, Jonathan and Roshan

 

5th Annual HPC Symposium - Keynote Speakers

  , , , , , , , , , , , , , , , ,

We are pleased to announce two keynote talks for the upcoming 5th Annual Bath HPC Symposium on Thursday 9th June.

The first keynote will be given by Dr Tom Connor from Cardiff University, titled "The Cloud Infrastructure for Microbial Bioinformatics (CLIMB); overcoming barriers to software use and data sharing in biology".

Genome sequencing has made it possible to examine fundamental biological questions over vast scales; from bacteria to man. Since the first bacterial genome was published 20 years ago, research focused around bacterial pathogens has been at the very vanguard of the revolution that has transformed biology into a data rich, data intensive field of science. Thomas will discuss how cloud approaches are being used in the MRC’s £8.5m CLIMB project to overcome key challenges that exist for most biologists today.

The second keynote will be delivered by Andy Mallinson from Intel. Andy will give us an overview of the Xeon Phi (MIC) architecture, some tips and tricks for developing, optimising and porting HPC codes to use them, a glimpse of Intel's future roadmap and the benefit these development will have for next-generation HPC systems.

We would like to take this opportunity to remind those who have not yet registered to do so, and to encourage participants to submit an abstract for a contributed talk or poster on their research.

Registration is currently open at https://bathhpc-2016.eventbrite.co.uk (deadline: Friday 27th May), and information about abstract submission can be found on the symposium website at http://go.bath.ac.uk/hpc-symposium (deadline: today, Friday 13th May).

We will be in touch again with further updates soon.

Best wishes,
Jonathan and Steven
