Hi all. I have looked at some of the stats other (extreme) users have listed and I have a question. I keep seeing things like this...
[64] NVIDIA GeForce RTX 2070 (4095MB) driver: 410.78 OpenCL: 1.2

Tell me there is no way this user has 64 video cards installed!!
Thanks

No they do not, however there is a way to recompile the Boinc software (it is open source) that allows a user to "spoof" the number of GPU's.

You will see it mostly used on Linux machines running the "special app" where a top range GPU, think RTX2080 can do a task in 60-90 seconds.

These users run out of work during the outage, due to the 100 work unit limit per GPU, and use this method to keep crunching 24/7

There is a thread on the Number Crunching forums where it is sort of explained.

It is not generally available, you need to download the Boinc software and make the alterations yourself.

Copy that. Makes sense. It was just throwing me for a loop.
Thanks
