SciNet Receives HPCwire Award

December 6, 2018 in blog, for_press, for_researchers, for_users, frontpage, in_the_news, news, Road_to_Niagara, success_story

We are very proud that SciNet has received the 2018 HPCwire Editor’s Award for Best Use of HPC in Physical Sciences. The award was announced at the 2018 International Conference for High Performance Computing, Networking, Storage and Analysis (SC18), in Dallas, Texas.

SciNet used Lenovo and Mellanox technologies on the new Niagara cluster to create spatial resolution models of the Pacific Ocean, helping to validate ocean waves movement and to assist in global warming calculations. These calculations were performed by a team of scientists involving University of Toronto’s Prof. W. Richard Peltier, University of Michigan oceanographer Prof. Brian Arbic, and NASA JPL’s Dr. Dimitris Menemenlis. More on this calculation can be found here.

This calculation was part of the “early science” program of the Niagara supercomputer at the SciNet HPC Consortion. In this short period in March of 2018, a number of scientists were given the opportunity to perform “heroic” calculations. These large scale calculation were essential to test, to tune and to get Niagara ready for use as a Canada’s fastest national academic supercomputer.

SciNet concludes its biggest-ever training week in scientific, high performance, and data science computing

June 19, 2018 in blog-general, for_educators, for_press, for_researchers, for_users, frontpage, news, success_story

When summer arrives, it means the return of Ontario’s Summer School on Scientific and High Performance Computing. This annual set of educational events bring together graduate students, undergraduate students, postdocs and researchers and gives them an opportunity to learn and share knowledge and experience in technical computing, data science and biomedical computing on modern high-performance computing platforms.

The summer school has been given at three locations for the last seven years and is a collaborative effort of the three High-Performance Consortia in Ontario: SHARCNET, CAC, and SciNet. This year, the first was from May 28 to June 1 in London, while the second one was hosted by SciNet on the St. George campus of the University of Toronto from June 11 to 15, and the third will take place in Kingston from July 30 to August 3.

HPC Python session at the 2018 summer school

High Performance Computing with Python (“Parallel Python”) Session at the 2018 Ontario HPC Summer School in Toronto

The format of the school is that of a five-day intensive workshop with mixed lectures and hands-on sessions on a number of selected topics. The topics slightly vary by location, but may include shared memory programming, distributed memory programming and general purpose graphics processing unit programming, and Python, R, machine learning, neural networks, visualization, debugging, bioinformatics and bioimaging. To make all these topics fit in one week, the lectures are organized in different streams. In Toronto, there was a high performance computing stream, a data science stream, and a biomedical stream, given by instructors from SciNet, SHARCNET, and CAMH.

This year was SciNet’s biggest summer school yet. For the first time, there were more than two hundred participants, from widely varying academic background like Business Administration, Dentistry, Biology, Medicine, Economics, Health Sciences, Phyics, Chemistry, Engineering, and Astronomy. Those who attended at least three days received a certificate of attendance.

To get a sense of the tremendous growth of this event, consider that in 2012, one of the first years of the summer school, in Toronto, we had 35 participants in the summer school, issued 20 certificates, and a total of 400 contact-hours were delivered by a handful of instructors. In 2018, these numbers are 7 to 10 times larger: there were 211 participants, 135 certificates were issues, and 3800 contact-hours were delivered by 17 instructors. If that is not a clear enough indication of the demand for this kind of training, consider this: within one day of opening the registration, there were over 100 registrations, and just one week later, the 200 registration mark was crossed. There were people on the waiting list, although we made an effort to try and accommodate most people in the end.

The school is offered for free, but without support for travel, lodging or meals. It is therefore not surprising that most participants are from the Toronto area, but there was a sizeable number of attendants from outside Toronto (60), from outside of Ontario (15) and even from outside Canada (5).

The participants seem to really appreciate the event, as borne out by the preliminary results from the post-event survey. From the survey, we got suggestions for improvements for the future, such as (even) more hands-on and better explanation of prerequisites and software for the sessions. Nonetheless, 94% of the respondents was very satisfied with the summer school, and thought the overall value of the summer school was high. 92% would recommend the event to their peers. Interestingly, the answers to the question “What was the most important thing you learned or did during the summer school?” varied a lot, indicating, perhaps, that the broad range of offered topics allowed participants to pick what suits them best.

Organizing the school was a tremendous experience, made possible by 8 instructors and staff members from SciNet, 9 from CAMH, and 2 from SHARCNET. The University of Toronto provided the space for the session, while Compute Ontario sponsored the coffee-and-cookie breaks.

If you missed it this time, look for the announcement next spring of the 2019 Ontario Summer School on High Performance Computing.

March 5, 2018 in for_educators, for_press, for_researchers, for_users, frontpage, in_the_news, news, Road_to_Niagara

The Niagara supercomputer was officially launched on March 5th, 2018. We were honoured by the presence and remarks of Reza Moridi (Ontario Minister of Research, Innovation and Science), Nizar Ladak (Compute Ontario President and CEO), Dr. Roseann O’Reilly Runte (CFI President and CEO), Prof. Vivek Goel (Vice-president of Research and Innovation at the University of Toronto), and Prof. W. Richard Peltier (Scientific Director of SciNet).

SciNet’s CTO Daniel Gruner gave an overview of the new system:

Niagara is located at University of Toronto and operated by the university’s high-performance computing centre SciNet, but the system is open to all Canadian university researchers.

Niagara is the fastest computer system in the country and is able to run a single job across all 60,000 cores thanks to a high-performance network which interconnects all the nodes. For more information on the configuration, see here.

A time-lapse of the building of Niagara is available (part of SciNet’s YouTube channel):

This system is jointly funded by the Canada Foundation for Innovation, the Government of Ontario, and the University of Toronto.

Road to Niagara 1: Tightly Coupled Cluster Decommissioned

October 25, 2017 in frontpage, news, Road_to_Niagara


This is the first of a series of posts on the transition to SciNet’s new supercomputer called “Niagara”, which will replace our aging General Purpose Cluster (GPC) and Tightly Coupled Cluster (TCS). The transition to Niagara will take place in the fall of 2017, and the system is planned to be available to users in early 2018.

To make room for Niagara, old systems will have to go. Because enabling research computing is our priority, throughout the process of installting Niagara, at least 50% of the GPC will be kept running. The GPC will not be completely switched off until Niagara is available.

The first cluster to go was the TCS. This was SciNet’s first supercomputer, a 102-node, 3264-core, IBM Power 6 system installed in January of 2009.

The TCS was shut off on September 29, 2017, and physically removed in October. The end of an era.

As the pictures below show, you don’t just put your old supercomputer to the curb, there is a bit of work involved in removing it. It took about 8 hours, 14 pallets, 10 racks, and 3 truck loads. And a $5 bill was found under one of the TCS racks, so we made some money as well!

Currently we are in mids of finalizing the contract for Niagara, so the next post in this series will provided more details on the new system to come.

Decommissioning the old Power 6 TCS requires a little fork lift; those are heavy nodes.

New Courses and New Initiatives for this Coming Semester

September 2, 2017 in for_educators, for_press, frontpage, news, Uncategorized


Excited about the beginning of a new academic year?

We, at SciNet, certainly are!

SciNet has created several new courses for this coming fall semester and we are really excited about that!
Take a look at our education website to learn about all the courses and workshops that we will be offering.

In addition to the traditional courses on Scientific Computing, we have also added courses on Computational BioStatistics, Machine Learning and Neural Networks, and basic level introductory courses for students without any previous background on computing or programming!

Additionally, several members of our team have obtained Graduate restricted appointed positions at the Institute of Medical Sciences and the Physics Department!

The number of SciNet courses that are listed as U of T graduate courses continues to increase (no small feat for a non-teaching unit like SciNet). Our full-term graduate courses in 2017/2018 are

Finally, starting this September we want to officially launch our “Research Initiative Program”!

This is a collaborative program, aimed to partner with research groups across the University, in order to boost and empower research.

Of course, research support is something that we have been doing since the beginning of SciNet, by providing technical support and the infrastructure to researchers for tackling their computational needs.
This program will go beyond that, by allowing researchers to explicitly partner with SciNet’s scientists, in order to pursue short and long term research projects.

More information about this program, ongoing collaborations and areas of expertise can be found at the
Research @ SciNet page.

Grand Opening of the ArcNet Space at MaRS

May 15, 2017 in blog-general, for_educators, for_press, for_researchers, for_users, frontpage, news, Uncategorized

On May 9, 2017, the Grand Opening of the ArcNet space took place (despite having moved a while ago). What is ArcNet? It is a space where expertise and support of Advanced Research Computing (the “ARC” in ArcNet) from three organizations come together. SciNet is the oldest of the three; It is the supercomputing consortium at the University of Toronto, which has been providing Canadian researchers with computational resources and expertise necessary to perform their research on scales not previously possible in Canada, from the biomedical sciences and aerospace engineering to astrophysics and climate science. SOSCIP is a research and development consortium that pairs academic and industry researchers with advanced computing tools to fuel Canadian innovation. The third organization, Compute Ontario, partners with the four academic computing consortia in Ontario aims to drive advanced computing to accelerate research and enhance competitiveness in the global marketplace resulting in a more prosperous Ontario.

The Grand Opening brought together many of our stakeholders, and was also attended by the Ontario Minister of Research, Innovation and Science, MPP Rezi Moridi, by the President of the University of Toronto Meric Gertler, by the Vice-President of Research at the University of Toronto Prof. Vivek Goel, and by the Scientific Directory of SciNet Prof. W. Richard Peltier. We were honoured that each was willing to say a few words about the opening of this space.

“This facility is a true partnership between the University of Toronto’s SciNet High Performance Computing Consortium, SOSCIP and Compute Ontario. Bringing them together in a state-of-the-art facility will strengthen their partnership and undoubtably create new opportunities to drive innovation through advanced computing in Ontario.” said Prof. Goel, one of the driving forces of the creation of the space.

The President of the University of Toronto reminded us that “With ARCNet, we have created an amazing hub of talent and technology that fosters collaboration between the public and private sector.”

Minister Rezi Moridi remarked that “Today we are here to celebrate the grand opening of the Advanced Research Computing facility. It is great to see that three organizations got together and set up this wonderful facility: SOSCIP,
Compute Ontario, and University of Toronto’s SciNet. I wish you all the best in serving our research community.”


The speeches were given in the new teaching and visualization room. This room holds up to 40 students and is already frequently used for courses and other events. It features a large visualization wall, i.e., a 13 x 7.5 feet ultrahigh resolution screen (8K, to be precise).


Two presentations were given by SciNet analysts to demonstrate the capabilities of this visualization wall; Ramses van Zon showed how to get insight into the complexity of the software installed on SciNet’s main cluster by using graph visualizations, while Marcelo Ponce showed visualizations of several aspects of interacting neutron stars, with data from numerical general relativity simulations.

You can see the capabilities of the visualization wall in the following video:
