PHYSICS-AWARE ARCHITECTURES: The diagram represents traditional computation. We insert energy and inputs into a mathematical operation and "hope" for a result. Needless to say, we create heat as a byproduct, no matter what traditional computation we attempt. The faster we want a result, the more heat is produced. So, what do we do with the excess heat? 

We can consider harvesting (converting heat back into energy) or cooling the hardware to avoid meltdowns/instabilities—neither is attractive.

Today, a staggering 40% of a data center's energy budget is dedicated to cooling. For every ten units of energy, only six units do actual computation—irreversible computing wastes 2/5 of the total energy budget. Looking at recent announcements, we see this quickly approaching 3/5. Sure, we can move the data centers to the Antarctic and hope for Fusion power, but it still doesn't solve the problem of today's inefficient computation.

Estimates show that Data Centers may consume up to 4.3 Trillion Cubic Meters of water (52% of which is potable) per year for cooling; to put this into perspective, the world's population consumes ~4 Trillion Cubic Meters. 

The good news about modern workloads, such as AI, is that they appear to be "embarrassingly structured" and "embarrassingly parallel"; there is less of the "embarrassingly unhelpful" data that modern CPUs tend to deal with. Unhelpful remains predominantly devices at the edge, i.e., the interactive systems. 

We know a better solution, as we stress the global energy production with inefficient irreversible computation (as in the old Coal Powered Computation of the digital era). The solution is to combine information and energy into a single-density flow equation. Doing nothing is the Ostrich method. We appear unwilling to leap. Each of us, in our capacity, can contribute to this shift by advocating for and adopting Physics-Aware Architectures. I do not see any way around this problem without bringing Physics into the foreground —designs that understand the thermodynamics and the energy+information movement within a circuit.

Vaire Computing is proud to sponsor the 16th Conference on Reversible Computation, July 4-5 in Toruń, Poland https://rc2024.mat.umk.pl/

As part of the sponsorship we are covering the registration, travel, and accommodation costs of students who want to attend but need financial support. At this time we cannot help with visas.

Vaire is a cutting-edge technology company with a mission to revolutionize the field of computer processors by surpassing the limitations of traditional transistor logic. The company is focused on pushing beyond the thermal constraints that challenge Moore's law, aiming to enable unprecedented advancements in computing power and information processing. Vaire seeks to attract top-tier talent from around the world to contribute to what could be a pivotal shift in computer science, potentially leading to a Nobel Prize-winning team.
