Statement about the Petya ransomware attacks


📥  Security

It’s been widely reported that a new ransomware worm has been affecting a large number of companies around which has the appearance of the Petya ransomware, though it comes with new abilities to spread within networks.

The bad news is that the severity of damage caused is very high and by  the time you see a warning message it is likely to be too late:

  •  In addition to using the vulnerability used by the recent WannaCry, it can also spread using hijacked account credentials using legitimate windows processes which has allowed it to spread very quickly within confined networks
  • The encryption mechanisms are very good so unencrypting data is likely to be impossible.  The communication mechanism has been disabled so even if payment was made, the key to decrypt the files would never be released

The good news is that worldwide spread will hopefully be contained:

  • It is likely that the main initial infection came through a compromised update to a piece of Ukrainian tax software
  • The malware only spreads to local computers or ones it is already connected to, it does not reach out across the internet looking for more victims

Whilst we have already patched the vulnerability used in WannaCry and have other protections in place, we will be looking to increase the measures in place to increase security.   Even with these protections in place there are no guarantees that a widespread ransomware infection would not strike us and everyone should take their own responsibilities seriously:

  • Do not open unexpected documents from unknown sources or if they seem suspicious
  • Avoid clicking embedded links found in unexpected emails
  • Apply patches to home computers and reboot work computers frequently to allow them to install

More information can be found from a number of trusted sites such as the BBC.



Ansys license change


📥  Software Licensing

In an effort to enhance the end user experience of using Ansys software on campus, Computing Services are implementing a solution that will dedicate Ansys research licenses to staff members and postgraduate students.

After the new license settings are applied, undergraduate students will be assigned Ansys teaching licenses only.

Many thanks

HPC Symposium 2017 - Delegation

We would like to thank everyone who joined us at the 6th Annual HPC Symposium on Monday!

"We have seen the symposium go from strength to strength and become established as a key event for bringing together the University's community of HPC developers and users. This year's symposium was excellent, with talks and posters that highlighted the variety and breadth of HPC usage across the campus, and outstanding keynote talks from two of the UK's leading HPC researchers. My thanks to the organisers who, once again, did a great job."
 - Prof David Bird, Chair of the HPC Management Group

This year, over 60 participants attended from within the University along with guests from the University of Bristol, University of Glasgow and from ClusterVision. There was a vibrant array of multi-disciplined contributions from our two keynote speakers, short talks and quick-fire flash presentations (Symposium Programme). The Symposium provided a great opportunity for networking and for learning about new developments in hardware, software and numerical techniques.

Our first keynote speaker, Prof Simon McIntosh-Smith (University of Bristol), Head of the HPC Research Group, discussed how to deal with the increasingly diverse range of competing architectures that software developers are faced with, many of which are available on Bath's own Balena HPC facility. Prof David Britton (University of Glasgow), who is a member of the ALTAS project at the Large Hadron Collider at CERN and leads the GridPP project, gave our second keynote and talked about the evolution of the Worldwide LHC computing grid and how this specialised research infrastructure is helping our understanding of the Universe.

HPC research at the University is innovative and various

The contributions from our community showcased the sheer variety of innovative HPC work being done across the University, covering:

  • modelling of rare events and aerospace composites;
  • designing buildings for thermal comfort;
  • molecular dynamics;
  • using GPUs to model the sea floor and the low frequency radio sky;
  • simulating quantum lattice states;
  • analysing global air quality; and
  • optimising partial differential equation solvers.

Thank you and congratulations

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

Lastly, we would like to congratulate our two prize winners, Jack Betteridge (SAMBa CDT, Mathematical Sciences) and Will Saunders (Mathematical Sciences), once again for their outstanding contributed talk and flash/poster presentation.

We look forward to seeing you again next year!

Best wishes,
Dr Steven Chapman (Computing Services)
Dr David Miranda (ACE)
Dr Jonathan Skelton (Chemistry)

Keynotes speakers:

We are pleased to announce two Keynote speakers for the 6th Annual Symposium on HPC.

The first Keynote will be from Simon McIntosh-Smith, from the University of Bristol, who will give a talk entitled: "Xeon and Pascal and POWER, oh Phi!”: how to cope in a world of increasingly diverse architectures".

Simon is a Professor of High Performance Computing and the Head of the Microelectronics Research Group. Just to mention some of his roles, he is a contributor to both the OpenCL and OpenMP parallel programming standards, regular member of the programme committee for IEEE/ACM SuperComputing and ISC and member of the EPSRC Archer national supercomputer design team.

Simon's research interests include: Performance portability, Application-based fault tolerance (ABFT), New algorithms for novel architectures, Heterogeneous, many-core processor architectures, including GPUs, Xeon Phi, FPGAs, DSPs etc., Scaling applications to run on millions of cores (Exascale computing).
The second Keynote will be from David Britton who is a member of the ATLAS collaboration, one of the experiments at the Large Hadron Collider at CERN ( He will give a talk entitled: "Evolution of the Worldwide LHC Computing Grid".

David is a professor of physics at the University of Glasgow and Project Leader of the GridPP project that provides Grid computing for particle physics throughout the UK. He is a member of the ATLAS collaboration, one of the experiments at the Large Hadron Collider at CERN with an interest in Higgs decaying to a pair of tau-leptons. Previously he worked on CMS, another of the LHC experiments, qualifying the crystals that make up the end-caps of the electromagnetic calorimeter. He has also worked at the Stanford Linear Accelerator (the BaBar experiment); Cornell (the CLEO experiment); and at DESY in Hamburg (the ARGUS experiment) with an emphasis on tracking detectors. Earlier work at TRIUMF in Vancouver established the most stringent limits on lepton universality through rare pion decays.

He has been involved with the GridPP project since conception in 2000 and was one of the lead authors of the proposals for all three phases. Initially appointed as Project Manager, he took over as the GridPP Project leader in 2008. GridPP is a collaboration of Particle Physicists and Computing Scientists from 19 UK Universities together with the Rutherford-Appleton Laboratory and CERN, who have built a Grid for Particle Physics.
