I'm not sure when this stuff popped up. although the MICRO-45 tutorial appeared after I put the first set of students on it. Anyhow, GPGPU-sim is pretty sophisticated now, with native nVidia ISA support, more accurate timing models, and even a power model. If we're going to get funding to adapt MARSS to support GPUs, then we have some serious competition. Not sure yet how to distinguish ourselves. But where we still have the edge is in having our own hardware implementation. Somehow, we need to leverage that, and I'm feeling a sense of urgency -- I don't want some other better-funded group to steal or thunder on this one. Anyhow, so I'm reading through the tutorials and looking for limitations we can overcome. Either we'll make our own, or we'll join them for simulation. But I think it's hardware (as a design at least, in gate-level simulation) where we need to focus, at least for the moment. Having a functionally verified design is excellent motivation to take us seriously. -- Timothy Normand Miller, PhD Assistant Professor of Computer Science, Binghamton University http://www.cs.binghamton.edu/~millerti/ Open Graphics Project
