Leading computational scientists and HPC technologists from the U.S., Europe, Japan and Canada will offer instructions on a variety of topics and also provide advanced mentoring. Topics include:

  • HPC challenges by discipline
  • HPC programming proficiencies
  • Performance analysis & profiling
  • Algorithmic approaches & numerical libraries
  • Data-intensive computing
  • Scientific visualization
  • Canadian, EU, Japanese and U.S. HPC-infrastructures

The expense-paid program will benefit scholars from Canadian, European, Japanese and U.S. institutions who use advanced computing in their research. The ideal candidate will have many of the following qualities, however this list is not meant to be a “checklist” for applicants to meet all criteria:

  • Familiar with HPC, not necessarily an HPC expert, but rather a scholar who could benefit from including advanced computing tools and methods into their existing computational work
  • A graduate student with a strong research plan or a postdoctoral fellow in the early stages of their research efforts
  • Regular practice with parallel programming (i.e., student utilizes parallel programming generally on a monthly basis or more)
  • May have a science or engineering background, however, applicants from other disciplines are welcome provided their research activities include computational work.

Students from underrepresented groups in computing are highly encouraged to apply (i.e., women, racial/ethnic minorities, persons with disabilities, etc.). If you have any questions regarding your eligibility or how this program may benefit you or your research group, please do not hesitate to contact the individual associated with your region below.

Interested students should apply by February 13, 2018. Participation, meals and housing will be covered for the selected participants, also support for intercontinental travel will be given (contingent to funding).

Gravitation waves detected, again!

June 15, 2016 in blog, blog-general, blog-technical, for_press, for_researchers, for_users, frontpage, in_the_news, news, success_story, Testimonials

We congratulate the LIGO and Virgo collaborations to the second-ever observation of gravitational waves from colliding black holes.

SciNet is proud to have contributed to the computation of the waveform templates that were used in this latest discovery of LIGO. LIGO measured about 55 gravitational wave cycles for this new binary black hole system. This large number of cycles made detailed computations of the expected wave-shapes more important than for the first detected black hole merger that was announced in February.

Canada is a leader of numerical calculations of colliding black holes, research led by Professor Harald Pfeiffer, Canada Research Chair for Numerical Relativity and Gravitational Wave Astrophysics at the University of Toronto. Pfeiffer states: I am very grateful for the sustained support of the SciNet team during the last 7 years; their support and the access to computing time on SciNet’s supercomputers have been crucial for my research program and its profound contributions to the LIGO discovery.

The top portion of the frame shows the horizons of the two holes, in this case, at the moment close to the merger of the black holes. The middle portion of the frame shows the gravitational waveform projected onto the LIGO Livingston detector. The bottom part shows the frequency of the gravitational waves, gradually increasing from about 35Hz to above 700Hz. For this system, LIGO could observe many more gravitational wave cycles than for the first discoved system (named GW150914).

Science Rendezvous 2016

April 28, 2016 in blog, blog-general, for_educators, for_press, for_researchers, for_users, frontpage, in_the_news, news, newsletter, success_story

Join us Saturday, May 7th for Science Rendezvous! It is an annual festival at the University of Toronto that takes science out of the lab and onto the street.

At the SciNet booth, explorers of all ages will find out how researchers use computers for discovery. They will see how simple computer simulations that you can run in your web browser or laptop can reveal important facts about how complex systems behave.

Gravitational Waves detected!!!

February 12, 2016 in blog, for_educators, for_press, for_researchers, for_users, in_the_news, news, success_story, Uncategorized

On February 11th, 2016 (10:30AM EST), scientists from Caltech, MIT and the LIGO Scientific Collaboration together with representatives of the National Science Foundation, announced in a live press conference, the first direct detection of gravitational waves.
The event detected, named GW150914, was produced by two colliding black holes, inspariling and merging together. This signal was detected by LIGO on September 14th, 2015.

Details of this discovery can be found in the following papers:

Many of the researchers running simulations and analysing data in several of our clusters are directly involved in the efforts for accurately modelling, simulating and detecting gravitational wave signals.
As a matter of fact, one of the simulations used for visualizing one of the movies screened during the announcement of the discovery of gravitational waves, was performed on SciNet’s General Purpose Cluster (GPC).

“The first detection of gravitational waves passing through Earth is a tremendous discovery. These waves were generated by never before observed astronomical objects, colliding black holes. I am very grateful for SciNet and Compute Canada to provide the computing resources needed to explore the properties of binary black holes, research that was instrumental in building the waveform-templates that LIGO used in its momentous discovery.”
Prof. Harald Pfeiffer (Canadian Institute for Theoretical Astrophysics, University of Toronto)

International HPC Summer School in Toronto

June 29, 2015 in blog, blog-general, for_educators, for_researchers, for_users, in_the_news, news, success_story


Eighty students from the US, Canada, Europe and Japan, plus about twenty speakers and over thirty mentors gathered at the University of Toronto from June 21 to June 26, 2015, to learn about High Performance Computing, and share experiences in this multi-disciplinary field (see Sponsored by PRACE, XSEDE, Riken, and Compute Canada , this was the sixth such advanced international summer school on High Performance Computing, which targets graduate students and postdocs who already have some experience in HPC parallel programming (for instance, MPI, OpenMP, or CUDA/OpenCL), preferably on software used in successful research projects.

Leading American, Canadian, European and Japanese computational scientists and HPC technologists offered instruction on a variety of topics, including HPC programming proficiencies, performance analysis, and visualization, as well as presentations of how HPC gets applied in fields such as geophysics, climate science, material science, cosmology, plasma phyiscs, and life sciences.

SciNet, a partner in the Compute Canada endeavour, was encited to be the local organization of this large international event.
It was an engaging week of instruction and networking that we hope has given the participants the skills and inspiration to use HPC resources to explore scientific projects at new and unprecedented scales.
