Crypto-currency miners have known this for years CPUs are effectively useless

GPU's way out perform CPU's from RAM to the speed of the CPU on the GPU. "Computex 2016 verdict: Behold the new brains of the computer"
I wonder why I can forgo the CPU for an all GPU setup in a gaming rig!

GPUs are still not efficient or often even capable of general purpose computing.
-
If you use the GPU for the CPU, the GPU becomes a CPU.

@DustinB3403 I don't think you've quite grasped the difference. CPUs are designed to do many different things quickly, while GPUs are designed to do a single thing very quickly. So it all depends on the workload. Got a bunch of weather information that needs the same calculations processed for a gigantic set of data points? GPU Got Fluid Elemental Analysis that uses a bunch of different calculations on a large number of data points? CPU.

Ya we def couldn't do CFD Solves with GPUs. Our new cluster has 20 nodes with 20 cores each.

Clustered?

They use a job scheduler to read and spread the load over free nodes. So they can be used together or separately.
They all have an infiniband backplane too.

MMmmm, good stuff. Any sort of job scheduler means they are being used as a cluster. Really all a cluster needs is something to tell everything where to run what. At least as I've always understood them.
Infiniband is just good stuff.

Right. I didn't want people thinking it was like a RHCS or something like that. It's a separate scheduler.
Ya we have a couple guys that will generate around 450-500GB per day of solves. We need the speed lol.
