I started out with a year number, but that was before the was Level A. Too many new CPUs only fall under level A unfortunately because they do not even have AVX.

On a very specific subset of ThinkPad P50 SKUs, particularly ones that come with a Quadro M1000M chip instead of the M2000M variant, the BIOS seems to have a very nasty habit of not always resetting the secondary Nvidia GPU between full reboots if the laptop is configured in Hybrid Graphics mode. The reason for this happening is unknown, but the following steps and possibly a good bit of patience

Hello, Some users have been complaining for years about their GPU sounding like a jet engine at take off. Last year, I finally laid my hand on one of these GPUs and have been trying to fix this issue on and off since then. After failing to find anything in the HW, I figured out that the duty cycle set by nvidia's proprietary driver would be way under the expected value. By randomly changing

For a while now we (Cray) have had some very primitive cache structure information encoded into our version of LLVM. Given the more complex memory structures introduced by Bulldozer and various accelerators, it's time to do this Right (tm). So I'm looking for some feedback on a proposed design. The goal of this work is to provide Passes with useful information such as cache sizes,
