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).

SciNet in partnership with STEM Fellowship (http://stemfellowship.org/), SAS and Open Data Toronto, organized the second edition of the “Big Data Challenge for High School Students”.

On Feb. 4th, the 2015/2016 Big Data Challenge for high school students took place. 8 teams from several schools across the GTA presented their research on data analytic in front of peers and judges.

Inspired by “Big Data in the City” theme, students gathered data from Open Data Toronto, analysed and investigated topics such as: immigration relocation strategies, emergency response for first responders services, identification of clusters in Toronto, environmental analysis of Toronto neighbourhoods, debt risk analysis of the city, collision patterns and prevention, data mining from social media related to energy efficient companies, among many others.

SciNet members, in addition to organize this event participated evaluating the initial proposals and judging the final 8 qualified for the final presentation.

Participants of the Big Data Challenge will be participating in tours to SciNet’s datacenter, as an unique opportunity to experience and visit the home of the largest super-computers in Canada!

 

Congratulations to all the participants!!!

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

toronto

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 https://ihpcss2015.computecanada.ca). 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.

Science Rendezvous 2015

20150509booth

We had a great time at Science Rendezvous on May 9th, 2015!

Science Rendezvous is an annual festival in Canada that takes science out of the lab and onto the street. The University of Toronto is one of the event sites, and SciNet has been part of this event for many years.

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

The most popular demonstration seemed to be slingshot, a game where the aim is to fire a laser beam towards a target (spaceship) through a set of black holes that change the beam’s trajectory. Other interactive simulations were a bouncing ball on a vibrating plate, a forest fire web application, and an ecological simulation of rabbits and wolves (the latter two are available at shodor.org).

Many thanks to the organizers who made this possible, and to everyone who turned out on a Saturday to discover science!

2015 Call for Compute Canada Resource Allocation Proposals

September 17, 2014 in blog, blog-general, for_educators, for_researchers, for_users, news

Compute Canada is announcing the launch of the 2015 Resource Competitions.  In addition to the familiar Resource Allocation Competition (RAC), there are two other opportunities to access Compute Canada resources including the Fast Track and the NEW Research Platforms and Portals (RPP) Competition.

I invite you to consult the Compute Canada website for additional details on these three opportunities and to be mindful of the deadlines below.  If you have any questions please contact rac@computecanada.com.

Resource Allocation Application Deadlines

Resource Opportunity Deadline
Fast Track October 2nd, 2014
Resource Allocation Competition October 20th, 2014
Research Platform and Portal Competition (Letter of Intent) September 25th, 2014

Background:  Compute Canada is leading the creation of a powerful national Advanced Research Computing (ARC) platform for research. This national platform integrates ARC resources at six partner consortia across the country to create a dynamic computational resource. Compute Canada integrates high-performance computers, data resources and tools, and academic research facilities around the country. These integrated resources represent a substantial computing capability and online and long term storage with rapid access and retrieval over Canada’s national, provincial and territorial high-performance networks.
