Existing processor architectures were designed in a time where the amount of energy to move data was roughly equal to the amount of energy required to do useful computation with that data.
Moving 64 bits from memory takes over 40x more energy than the actual double precision floating point operation being performed with that data.
REX Computing is rethinking the traditional hardware managed cache hierarchy, and in removing unnecessary complexity, is able to significantly reduce power consumption and total area.
REX Computing is developing a new, hyper-efficient processor architecture targeting the requirements for the supercomputers of today, and all the computers of tomorrow.
To do this, we are throwing out the feature creep and bloat of processors of the past 30 years, and using improvements in the world of software to greatly simplify the processor itself to only what is necessary.
In doing so, we are able to deliver a 10 to 25x increase in energy efficiency for the same performance level compared to existing GPU and CPU systems
256 GFLOPs (Double Precision) or 512 GFLOPs (Single Precision)
at 64 to 128 GFLOPs/watt
Software development is an important part of the Neo architecture roadmap. The REX software team is working hard to build an easy-to-use modern toolchain to simplify writing new Neo applications and porting existing software to our platform.
A fundamentally new hardware environment brings about several exciting
Thomas worked at the MIT Institute for Soldier Nanotechnologies for 3 years as both an end user of HPC systems, and later transitioned into designing and building them at the lab. This experience led to starting REX Computing in 2013 as a recipient of Peter Thiel’s “20 Under 20” Fellowship, where he leads architectural design and operations. Thomas has been featured on Forbes’ 30 under 30 list and is a project lead for the Open Compute Project HPC Group.
Paul started programming as a child, and studied CS at Georgia Tech. He has worked in fields including structural biology, theoretical ecology, and nanofabrication. Paul was part of the 2012 class of Thiel Fellows, where he founded a synthetic biology startup and worked at Lawrence Berkeley National lab for 18 months. He later joined Thomas in starting REX, where he contributes an extensive knowledge of low level software and tool development

Moving data on a chip can take 40 times more energy than to compute that same amount of data. It also slows things down. So by tweaking the memory to make it less locked down in the hardware, REX is saving energy and boosting speed.
