By skimming through the code, this seems to have the same data-flow model as Intel's TBB, but extended to distributed memory configurations using MPI as backend.

I was mainly curious about the performance hit of drawing operations. But your subjective assessment is enough to understand that the penalty is lower than I expected.

While I agree with the article's reasoning, I never seen the argument on performance. Could it be that the overhead of Plan9 "everything is a file" abstraction was too much to handle when compared with the more pragmatic UNIX

Overall I love the Steam Machines idea. I have many games in my library and I can't wait to play them in the living room with my friends. I think that what Valve got wrong was just two topics: - There is no game compatibility informat

The MPI+OpenMP duality has been around the HPC community as a for of heterogenous computing. Recently, with the addition of CUDA to the mix, HPC codes have added yet another code path; I'm skeptical about the maintainability of such sy

Very nice and polished game! Small problem I encountered: whenever I died in the game, the dungeon I respawned at was much easier than the initial one.

I've been reading about Plan9 for a while. While I love the elegance of everything being a file addressable through the 9P protocol, I wonder about the feasibility of piping a "framebuffer" or other heavy process. Does someon

>> In this approach, threads own their data, and communicate with message-passing. This is the same paradigm as MPI, the message parsing interface. Using it, you also get for free the ability to deploy your "threaded" code i

The abstract reads "Nicotine addiction negatively correlates the changes of developing Parkinson's disease". I'm not a fan of the wording of the HW title to make it sound like smoking could be a good habit.

> As described in Section 3, our prototype uses a loadable kernel module to [allow the GPU to monitor the keyboard buffer]. We should note that this choice was made only for convenience, and the same stealthy approaches that are typicall
