Dissecting the NVIDIA Volta GPU Architecture via Microbenchmarking
- senatorobama 9y agoMost interesting is who published this (Citadel, LLC)
- SSLy 9y agoAnd who are they?
- dogma1138 9y agoOne of the largest US hedge funds.
- arbie 9y agoGPGPUs and CUDA have been used for predictive financial analysis for some time now, haven't they?
- WhitneyLand 9y agoA hedge fund backs research into GPUs because they may deal in finance and GPUs can be used for financial analysis? Not a chance. This has nothing to do with their IT department or back office requirements.
- dogma1138 9y agoIt is 100% from their "IT", Citadel is essentially a "Quant" firm. https://www.citadel.com/careers/ultimate-guides/quantitative-researcher/ https://www.citadel.com/careers/ultimate-guides/quantitative... https://wei-tan.github.io/ https://wei-tan.github.io/ https://www.citadel.com/careers/the-data-open/ https://www.citadel.com/careers/the-data-open/
- WhitneyLand 9y agoOk, my mistake. Not a chance was the wrong way to put it. The point is hedge funds have no fundamental link to algorithmic trading or requiring low level GPU optimization as a core competency. Some of them do, and maybe the number is growing, but it’s a subset, not something that defines what a hedge fund has to be.
- nylonstrung 9y agoCitadel is not a pure play quant fund, they have a ton of PMs doing conventional fundamental equities
- dbuder 9y agoYes, but imo this was funded as research into semiconductor companies and possibly part of a short on nvidia. The recent AMD vulnerabilities were part of a short strategy.
- DoritoChef 9y agoI wonder how long it took to compile all of this. Great work!
- shaklee3 9y agoI believe the results were presented at GTC this year, and they said the paper (this) was to follow. edit: Here is the talk: http://on-demand.gputechconf.com/gtc/2018/video/S8122/ http://on-demand.gputechconf.com/gtc/2018/video/S8122/ and slides: http://on-demand.gputechconf.com/gtc/2018/presentation/s8122-dissecting-the-volta-gpu-architecture-through-microbenchmarking.pdf http://on-demand.gputechconf.com/gtc/2018/presentation/s8122...
- wmf 9y agoInstead of NVidia just documenting their uarch, third parties reverse engineer it and present it at... NVidia's conference.
- gmueckl 9y agoPapers like this have been written for older GPU architectures and it is disappointing to even have the need for them. That such a paper was presented at a manufacturer's conference is icing on the irony cake. My underdeveloped tinfoil hat speaks that they want to acknowledge the reverse engineering methods involved and are secretly hoping that they get applied to the competition, too, so they can extract the competitor's secrets from a public source instead of ending up in a reverse engineering grey area.
- DoritoChef 9y agoI'm kinda surprised the Nvidia was totally cool with this presentation. Maybe the engineers think this info should be commonplace but are trapped in NDA hell?
