SciNet’s publication about Niagara deployment

Have you ever wondered how a supercomputer is designed and brought to life?
Read SciNet’s latest paper on the deployment of Canada’s fastest supercomputer: Niagara.

Niagara is currently the fastest supercomputer accessible to academics in Canada.
In this paper we describe the transition process from our previous systems, the TCS and GPC, the procurement and deployment processes, as well as the unique features that make Niagara a one-of-a-kind machine in Canada.

Please cite this paper when using Niagara to run your computations, simulations or analysis:

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.

HPCwire: SciNet Launches Niagara, Canada’s Fastest Supercomputer

Launch of the Niagara Supercomputer at SciNet

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 3: Hardware setup

March 5, 2018 in blog-technical, for_press, for_researchers, for_users, news, Road_to_Niagara, Uncategorized

This is the fourth of a series of posts on the transition to SciNet’s new supercomputer called “Niagara”, which will replace the 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.

The University of Toronto has awarded the contract for Niagara to Lenovo, and some of the details of the hardware specifications of the Niagara system have been released:

The system will have the following hardware components:

  • 1,500 nodes.
  • Each node will have 40 Intel Skylake cores (making a total of 60,000 cores) at 2.4 GHz.
  • Each node will have 200 GB (188 GiB)of DDR4 memory.
  • The interconnect between the nodes will be Mellanox EDR Infiniband in a Dragonfly+ topology.
  • A ~9PB usable shared parallel filesystem (GPFS) will be mounted on all nodes.
  • A 256TB Excelero burst buffer (NVMe fabric, up to 160 GB/s) will be available for fast I/O.
  • Peak theoretical speed: 4.61 PetaFLOPS

Niagara is estimated to be installed and operational towards in March 2018, and ready for users not too long after.

Even before official ready-date, there will a period in which select users can try out and port their codes to Niagara.

After the friendly-user period, all current users of the GPC (and former users of the TCS) will get access to Niagara.

The large core count, ample memory per core, and fast interconnect support Niagara’s intended purpose to enable large parallel compute jobs of 512 cores or more.

The software setup will also be tailored to large parallel computations. Nonetheless, there will still be a fair amount of backfill opportunity for smaller jobs.

The setup of Niagara is intended to be similar in spirit to the GPC, but different in form: scheduling per node, a home, scratch and possibly project directory defined in environment variables, a module system, and access to our team of analyst to help you get your codes running, and running well.
