There is an optinal header field in the power budget table we can use to read out the power cap of the GPU. We should have this in the kernel before actually using it to catch errors and see how reliable this is, but as it seems it works on all GPUs as expected on Kepler und Maxwells with the power cap field set in the vbios. This series keeps things really simple for now until we figure out

Hi all, I've ecountered a problem in the last few days with my .Rhistory file not being able to be updated when I quit an R session because its file attributes under Windows have been set as "Hidden".

Hi! I am quite a new user of R. I wanted to ask if there was some package for dynamic panel analysis (with Arneallo-Bond Method) like stata. PLM is for panel analysis but not for dynamic. Best regards, Tanveer

There is an optinal header field in the power budget table we can use to read out the power cap of the GPU. The meaning of this header field was confirmed with nvidia-smi -q: The rows "Min Power Limit", "Power Limit" and "Max Power Limit" are set to the "min", "avg" and "max" values from the referenced power budget entry respectively.

Hello! I am using the TeXmacs interface to R. (Though I encountered a similar problem when using Sweave) In doing calculations I often ecounter this scenario: I'll have some calculations in my file: -- A=read.lots.of.data() B=huge.calculation.on(A) C=another.calculation.on(B) -- Now, if A has already been read, I don't need to re-read it. If B has already been calculated, I don't need to recalculate it. But I would like...

Adds Nouveau controlled thermal throttling for Kepler+ GPUs. With this I feel safe enough to add support for Maxwell2 reclocking later on (still hidden behind a switch, but we can be fairly sure to not overheat hardware if a user isn't carefull enough) Contains all patches from my clk update series, but I thought it makes sense to include those in this series as well for completness. Please

First patch fixes a potential vbios parsing bug on Fermi GPUs, but it may also affect Kepler ones. Second patch wakes the GPU up whenever the user tries to reclock to prevent the write to the pstate file from freezing.
