SciNet News April 2015
April 9, 2015 in for_researchers, for_users, newsletter
First of all, we want to take this opportunity to thank all of you who cleaned up their scratch directories last week when /scratch it was 99% full. You saved the file system!
Below you will find the salient points of what else happened or changed recently and what will happen in the near future. Among these is the announcement of the Ontario High Performance Computing Summerschool, which has three installments, one of which is to be held in Toronto in July. As always, details on SciNet events are available on the wiki and the SciNet education website.
UPCOMING EVENTS
Unless stated otherwise, all events take place at the SciNet Conference Room on the second floor of 256 McCaul Street, Toronto. All events at SciNet are free for users but we ask that you enroll on the education website: https://support.scinet.utoronto.ca/education.
- INTRO TO SCINET
Wednesday April 8, 10:30 am – 11:30 amThe “Intro to SciNet” is a class of approximately 90 minutes where you will learn how to use the systems. Experienced users may still pick up some valuable pointers during these sessions.
Participation counts towards the SciNet HPC Certificate.
For more information and enrollment, go to https://support.scinet.utoronto.ca/education/go.php/172/index.php
More intro sessions to be held in the near future: May 13, 10:30 am – 11:30 am: https://support.scinet.utoronto.ca/education/go.php/173/index.php
Jun 10, 10:30 am – 11:30 am: https://support.scinet.utoronto.ca/education/go.php/174/index.php
- SCINET USER GROUP MEETING
Wednesday April 8, 12:00 noon – 1:00 pmThe SciNet Users Group (SNUG) meetings are every month on the second Wednesday, and involve pizza, user discussion, feedback, and a half-hour talk on topics or technologies of interest to the SciNet community.
TechTalk: “Smoothed Particle Hydrodynamics” by Marcelo Ponce (SciNet)
In this talk I’m planning to review the main concepts used in “Smoothed Particle Hydrodynamics”, a technique widely used for simulating fluid dynamics. In particular I will focus in the basic concepts and their applications to astrophysical simulations, such as, the effects on accretion disks surrounding a gravitational recoiled black hole, and “mergerburst” events where the interaction between stars may trigger luminosity outburst (suhc as the outburst of V838 Monocerotis observed some years ago).

Future SNUGs: May 13, 2015, 12:00 noon – 1:00 pm, TechTalk TBD
Jun 10, 2015, 12:00 noon – 1:00 pm, TechTalk TBD - INTRODUCTION TO CUDA
Tuesday April 14, 9:00 am – 5:00 pmThe goal of this course is for incoming students, new to GPGPU but familiar with scientific programming in C or C++, to leave being able to start writing simple kernels for their own problems, and understand the tools, techniques and libraries that will be needed to improve and optimize the results.
Participation counts towards the SciNet HPC Certificate.

- RELATIONAL DATABASE BASICS
Wednesday May 6, 9:30 – 5:00 pmAs a form to manage data, relational databases are widely used in the back-end of many websites as well as for data mining computations. In this course, we will look at the basics of relational databases: What are they, and what are they useful for? We will also consider why they are not all that much used in the context of scientific computing, using SQLite and Python.
Participation counts towards the SciNet Scientific Computing Certificate.

- XEON PHI DEVELOPER TRAINING
Tuesday May 19 and Wednesday May 20, 9:30 am – 4:30 pmOn May 19 and 20, 2015, Intel is giving a two-day workshop in Toronto for software developers on the foundation needed for modernizing their code to take advantage of parallel architectures found in both the Intel Xeon processor and the Intel Xeon Phi co-processor.
Note that a substantial difference with the one-day workshop on the same topic given in Toronto on October 27, 2014, is the second day, which consists of a hands-on lab in which you get to use the material and techniques presented in the first day.
This is an external event organized by Intel. For more information and registration please go to

- COMPUTE ONTARIO RESEARCH DAY
Thursday May 21 Conestoga College Institute of Technology and Advanced Learning Cambridge, OntarioA day filled with high performance computing related research done in Ontario. Have an interesting research story for which you used high performance computing (such as the facilities at SharcNet, SciNet, and HPCVL)? Want to share you experience with other Ontario HPC users? Consider giving a talk at the meeting.
More details and registration at https://www.sharcnet.ca/events/CORD2015
- ONTARIO HPC SUMMER SCHOOL 2015
The Compute Ontario Summer School on High Performance Computing provides attendees with opportunities to learn and share knowledge and experience in high performance and technical computing.
As in previous years, the Summer School on High Performance Computing 2015 will have three installments:
“West” May 25 – 29 Western U. (London) “Central” July 13 – 17 U. Toronto (Toronto) “East” July 27 – 31 Queen’s U. (Kingston)
The format will be a five day workshop with mixed lectures and hands-on sessions on a number of selected subjects such as MPI, CUDA, OpenMP, Python, and Visualization (the subjects will vary slightly depending on the location). These sessions will be organized in two parallel streams.
Parts of this event may count towards the SciNet HPC Certificate.
More details regarding the summer school program, location, and registration (for either of the three installments), will become available at https://www.sharcnet.ca/events/ss2015
