The dawn of interactive supercomputing
Imagine you can see the results of you calculations on a supercomputer in real-time. At SC14 we showed, in the world's largest live in-situ visualisation running on 1024 GPUs, that it is possible (1,2,3,4).
SC14 Gordon Bell Prize finalists
Last year we tried, but did not succeed. This year is different, and our
submission was selected as a finalist for the Gordon Bell Prize at
the Supercomputing 2014 conference.
It was an amazing project with an ambitious goal to model the Milky Way Galaxy on a star-by-star basis using the Titan supercomputer. While we weren't able to simulate the whole Galaxy one a star-by-star basis, we did simulated a slight smaller model with a total of 50 billion particles using Swiss Piz Daint supercomputer. This is the biggest Milky Way simulation by far (1000x more particles), and it provides wealth of data to compare with observations. Our application also achieved a sustained performance of 24.8 Petaflops on 18600 GPUs on Titan supercomputer. Once the team will be able to secure more compute time, we have all the tools at our disposal to simulate the Milky Way with about 50 billion stars (or about 300 billion particles in total, most of the particle will comprise Dark Matter).
Intel Composer XE 2013 SP1 & VTune
After long delay, I am finally able to write something here.. Last few days I spent figuring out why VTune 2013 U12 & 13 freezes after profiling an app..
SC13 - Gordon Bell Prize submission
Today we received an email with sad news that our SC13 submission to Gordon
Bell Prize category was rejected :(
Has gold finally bottomed?
Gold appears to be the most hated asset these days, no-one wants it or its
derivatives, e.g. miners, at any prices no matter how low they are. This will
stop, however, because the best cure for low prices is low prices.
