How can I dowload the video? I have trouble watching it because it keeps stopping every 5 seconds. I have a 3 mbs connection.

Hi Art-

Glad you enjoyed the video!

1) For the initial release, the Concurrency Runtime is targeting CPUs.

2) We internally have a suite of performance tests, though I don't know at this time whether such a suite would be released publicly. There are of course industry standard suites, many of which have emerged from the HPC space, and I imagine at some point some subset of those will be publicly ported to run on the runtime once it's released.

3) To your last question, we have team members that focus on hardware, on software, and the interplay between the two.

Thanks,
Stephen

Thanks, Great stuff can't get enough, looking forward to PDC presentations, etc.

Is TCR: FGP "equal" on all many-core CPUs, GPUs, CPU-GPUs?

Is there a suite of performance tests? Same app/code on different chips? (Or must we wait for marketing pr wars?)

Do you have any hardware guys on your team or do you depend on industry contacts for down to the metal knowledge to inform your architecture, TCR: FGP?

Very enjoyable vid, most surprised that for the first time I see managed code affecting unmanaged, and not the other way around which it always is. Lambdas in C++? WOW!

I also see almost no difference in the objective between managed and unmanaged worlds, notwithstanding the fact that native code is "closer to the metal" than managed code. I'm pretty sure that an algorithm that works well concurrently in C++, will also work well in C# and vica-versa (most of the time).
