Comment Feed for Channel 9 - DirectCompute Lecture Series 210: GPU Optimizations and Performance http://ecn.channel9.msdn.com/o9/ch9/9/2/7/7/5/5/DirectCompute210_512_ch9.png Channel 9 - DirectCompute Lecture Series 210: GPU Optimizations and Performance Join James Fung from Developer Technology at NVIDIA as he covers the following advanced topics for DirectCompute:    Work distribution best practices   Compute shader code best practices   Algorithm selection best practices   Multi-GPU best practices He also gives an example problem, scan/reduction, and then goes through various optimizations for that problem. For more information on DirectCompute, download the PDC 2009 DirectCompute HOL, watch the DirectCompute Roundtable discussion, see the full DirectCompute lecture series, and download the slides for this lecture. en Wed, 19 Jun 2013 11:08:36 GMT Wed, 19 Jun 2013 11:08:36 GMT Rev9 Re: DirectCompute Lecture Series 210: GPU Optimizations and Performance Where we can find the presentations?

The code is not visible in the movies

Wont we get the same problem in the GPU as in the CPU when all applications start using the GPU ? ( contention, GPU gets overloaded, which means delays, etc... )

So in other words we are just moving/postponing the problem.

Do you have any thoughts about this ?

In my opinion, description of algorithm cascading along with Brent’s theorem is pretty important, but unfortunately it is missing in the current talk. Otherwise, great lecture, thank you James!
