In the world of hi-tech hype, it's mind-numbing how often we're told about the ‘next big thing’. Yet every now and then, something comes along that surely deserves our attention. A sprightly young startup, Flow Computing, is claiming to have developed technology that could change how we think about processing power; and its bold claim is a parallel processing unit (PPU) that can multiply the power of a central processing unit (CPU) by as much as 100 times.
Every great invention starts with a dream. Flow Computing’s PPU is a radical new technology that promises to give every computer a massive power BOOST, turning any CPU, from the mid-range to the supercomputer elite, into a speed demon. But how is this PPU supposed to work to enhance the power of our gadgets?
Spearheaded by the brains trust behind the VTT Technical Research Centre of Finland, Flow Computing’s PPU is far more than a question of sheer speed. Instead, it’s a question of more intelligent, more efficient processing. Handing over many workloads to the PPU is what Flow Computing says will be the next step towards SUPER CPUs. Consider the implications. Imagine chips that run not just 100 times faster but which, on top of that, will be fully backward compatible with existing software and applications – those programmed to run on present-day Intel-compatible processors. That means that applications written for silicon processors will run without modification under the PPU. Not exactly a futuristic concept, but developers will have to make changes to their applications if they wish to fully harness the processing power on offer. The game-changer is that developers will be working with hardware that’s able to runs tens of times faster than Intel’s current roadmap without any alterations.
But Flow Computing is a new company that emerged in January with a tiny handful of employees and just $4.3 million in funding – and yet the company has decided to set its sights high. It’s not alone. By courting giants such as Intel and Nvidia, and planning to license its PPU technology ‘worldwide’, Flow Computing is poised to influence the CPU market on a scale not yet seen.
However, Flow Computing is hoping it will not only be used in desktops and data centres. The company wants to bring it to the one form of technology that remains hopelessly underpowered today: standard consumer devices. The company’s PPU could potentially bring huge increases to the performance of your smartphone, your watch, maybe even any device with a CPU. Bringing much more computing power to the mobile field, whether in the form of a phone, a watch, a car or some other mobile device, that’s a user experience that could change everything.
But in reality, what lies between ambiguous promise and physical artifact is a long, unforgiving road. For the time being, Flow’s ‘revolutionary’ chip has yet to be built, making it almost impossible to vindicate its lofty claims. And then there’s the long and winding road that needs to be travelled to pick up steam and scale up to a global BOOST for CPUs: it will depend on the company’s ability to navigate the challenging landscape of tech development and collaboration.
While the future is uncertain, as we stand on the cusp of the possible fulfilment of Flow Computing’s vision, the technology behind the PPU – built as much to aid and enable the CPU as much as to boost the units connecting to it (eg, GPUs) – is a glimmer of optimism amid a growing stagnation in raw CPU speed.
The consequences of a successful PPU process could be far-reaching: imagine anything that depends on number-crunching, from simulations to cutting-edge visual effects – the daily functioning of contemporary computing could be affected, in different ways, to an estimated greater or lesser degree. The crucial question, for now, is to see whether Flow Computing manages to transform speculation into reality – whether the leap from theory to concrete, from projection to something that, before they know it, alters the way their computers work, can actually be made.
At its core, Flow Computing’s idea of boost is more than about speed alone; it enables entirely new futures for computers while unshackling them from the very limitations that have stifled progress for years. If the PPU shows us anything, it’s the potential of human ingenuity in the form of Moore’s law to continue. In the big picture of technological history, such cameras as the PPU serve as a reminder that the potential for pushing the limits is immense. Will Flow Computing come up with a technology that gives us a boost towards ever high levels of computing performance? It’s a question to be answered in the future. But one thing seems clear: in technology, the tale of speed never ends, and the desire to turbo-charge tools to do more, faster, will always be with us.
