We are hosting our next LLVM / Clang Social Meetup in Toronto on Thursday, 
February 27, 2020. So if you are around the Toronto-area on February 27th, 
come out for a chance to meet your fellow community members and listen to 
the talk.
If you would be interested in attending this event or other events in 
future, please join the LLVM-Clang-Toronto-socials group on meetup: 

The following is the schedule for the meetup:
Date: Thursday February 27th, 2020
Time: 6:00 pm (presentations start at 6:30 pm).
The front building door has restricted after hours access so please arrive 
before 7pm.   


6:00 – 6:30 pm Social Interaction
6:30 – 7:30 pm Presentation ("Khronos SYCL and oneAPI: Heterogeneous 
Programming with Modern C++ and Machine Learning" - Presented by Michael 
7:30 – 8:00 pm Q &A / Discussions.

Mozilla Toronto 
366 Adelaide St W‎. Suite 500 
Toronto, ON M5V 1R9, Canada   

The event will be in the Union Commons which is through the doors on the 
right if you are facing the reception desk. 

Public Transport:
We are a 5-10 minute walk from Toronto's subway system (St. Andrews 
Station), but the 501 Queen streetcar (2 minutes North of the office), 510 
Spadina streetcar (just West of the office) and 504 King street (1 minute 
South of the office) are also easy to use and provide frequent service. 
Talk Abstract:

"Khronos SYCL and oneAPI: Heterogeneous Programming with Modern C++ and 
Machine Learning"
Presented by Michael Wong (http://wongmichael.com/about)

SC19 was my twelfth trip to the International Conference for High 
Performance Computing, Networking, Storage and Analysis, I recall my first 
event was SC08. In a way we have come full circle, first making C 
available to the heterogeneous world in 2008 through OpenCL, and now 
making modern C++ available in 2019. During that time, we had already 
gained a great deal of experience with making Modern C++ heterogeneous, 
with examples from OpenMP, Kokkos, Raja, C++ AMP, HPX, and SYCL. We are 
now in the process of bringing that experience to ISO C++.

For me personally, I have been dreaming of something like SYCL and oneAPI 
since I was involved with OpenMP. Even back then, I had always wished 
there was one programming model that could be used to serve both the HPC 
and the embedded space—instead of multiple models. SYCL helps to satisfy 
that goal.

The C++ Direction Group has set a future direction for C++ and includes 
recommendation for C++ in the short and medium term. The first half of 
this talk will devote to the issue of 3Ps: Performance, Portability and 
Productivity. The other parts will consider the C++ Directions Group’s 
description of where future C++ is heading. It also includes a guidance 
towards Heterogeneous C++.

The rest of this talk presents some of the challenges and solutions to 
implement a Heterogeneous C++ standard in Clang based on our 
implementation of Khronos's SYCL language with Codeplay's ComputeCpp 
compiler and my previous experience with OpenMP/OpenACC, with the fast 
growth of C++ and clang being a platform of choice to prototype many of 
the new C++ features. We also demonstrate the ecosystem that Codeplay has 
built to support Machine Learning using SYCL.
