Modern Hardware

Graphical Processing Units (GPUs) have been traditionally used for fast 3D game rendering, However over the past decade they have been harnessed more broadly to accelerate computational workloads in areas of scientific computing including those related to oil and gas exploration and production.

Today’s leading generation GPUs offer roughly 10x more bandwidth and FLOPS than CPUs.  The charts to the right compare the evolution of these metrics on GPU and CPU over the last decade.  GPU technology has dramatically grown and outpaced CPU technology during this time and all signs point to this trend continuing. ECHELON uses that full capability to offer game changing performance which will only improve as GPU technology advances into the future.



Bandwidth is very important in reservoir simulation since most reservoir simulation is bandwidth bound.  Because ECHELON has been written from inception to run on GPUs, it is able to take full advantage of the bandwidth offered by each new generation of GPUs.  The chart to the right shows how ECHELON's performance is almost linear to the amount of bandwidth provided by each GPU.  This demonstrates how ECHELON's performance will continue to increase with each new evolution of GPUs.

P100 Bandwidth


Modern GPUs have up to 32 GB of memory allowing users to simulate up to 12 million active cells on a single GPU.


Compute bound simulation

ECHELON shows near linear compute performance increase with each new generation of GPUs, showing that ECHELON's performance in compute bound simulation will continue to increase.
