Interview: Mark Potter, CTO, HPE

The Machine is the most important analysis and growth programme in HPE’s historical past. Its purpose is to ship memory-driven computing.

Reminiscence-driven computing places reminiscence, not the processor, on the centre of the computing structure. The Machine represents HPE’s analysis programme for memory-driven computing. Applied sciences popping out of the analysis are anticipated to be deployed in future HPE servers.

The elevator pitch is that as a result of reminiscence was once costly, IT techniques had been engineered to cache incessantly used knowledge and retailer older knowledge on disk – however with reminiscence being a lot cheaper in the present day, maybe all knowledge may very well be saved in-memory relatively than on disk.

By eliminating the inefficiencies of how reminiscence, storage and processors at present work together in conventional techniques, HPE believes memory-driven computing can cut back the time wanted to course of complicated issues from days to hours, hours to minutes, minutes to seconds, to ship real-time intelligence.

In an interview with Pc Weekly, Mark Potter, chief expertise officer (CTO) at HPE and director of Hewlett Packard Labs, describes The Machine as a completely new computing paradigm.

“Over the previous three months now we have scaled the system 20 occasions,” he says. The Machine is now operating with 160TB of reminiscence put in in a single system.

Superfast knowledge processing

Quick communication between the reminiscence array and the processor cores is vital to The Machine’s efficiency. “We will optically join 40 nodes over 400 cores, all speaking knowledge at over 1Tbps,” says Potter.

He claims the present system can scale to petabytes of reminiscence utilizing the identical structure. Optical networking expertise, comparable to splitting gentle into a number of wavelengths, may very well be used sooner or later to additional improve the pace of communications between reminiscence and processor.

Trendy pc techniques are engineered in a extremely distributed vogue, with huge arrays of CPU cores. However, whereas now we have taken benefit of elevated processing energy, Potter says knowledge bandwidth has not grown as rapidly.

As such, the bottleneck in computational energy is now restricted by how briskly knowledge will be learn into the pc’s reminiscence and fed to the CPU cores.

“We imagine memory-driven computing is the answer to maneuver the expertise business ahead in a method that may allow developments throughout all facets of society,” says Potter. “The structure now we have unveiled will be utilized to each computing class – from clever edge gadgets to supercomputers.”

Compute energy past examine

One space of curiosity for this expertise is the way it may very well be utilized to construct a high-performance computer (HPC), comparable to an exaflop-scale supercomputer.

The Machine may very well be many occasions sooner than all of the Top 500 computers mixed, he says, and it will use far much less electrical energy.

“An exaflop system would obtain the equal compute energy of all the highest 500 supercomputers in the present day, which devour 650MW of energy,” says Potter. “Our purpose is an exaflop system that may obtain the identical compute energy as the highest 500 supercomputers whereas consuming 30 occasions much less energy.”

It’s this concept of a pc able to delivering extremely excessive ranges of efficiency in contrast with techniques in the present day, however utilizing a fraction of energy of a contemporary supercomputer, that Potter believes will probably be wanted to assist the subsequent wave of internet of things (IoT) functions.

“We’re digitising our analogue world. The quantity of information continues to double yearly. We will be unable to course of all of the IoT knowledge being generated in a datacentre, as a result of choices and processing should occur in actual time,” he says.

For Potter, this implies placing high-performance computing out on the so-called “edge” – past the confines of any bodily datacentre. As a substitute, he says, a lot of the processing required for IoT knowledge will should be achieved remotely, on the level the place knowledge is collected.

“The Machine’s structure lends itself to the clever edge,” he says.

One of many tendencies in computing is that high-end expertise finally leads to commodity merchandise. A smartphone most likely has extra computational energy than a classic supercomputer. So Potter believes it’s completely possible for HPC-level computing, as is the case in a contemporary supercomputer, for use in IoT to course of knowledge generated by sensors domestically.

Contemplate machine studying and real-time processing in safety-critical functions. “As we get into machine studying, we might want to construct core datacentre techniques that may be pushed out to the sting [of the IoT network].”

It might be harmful and unacceptable to expertise any sort of delay when computing safety-critical choices in actual time, comparable to for processing sensor knowledge from an autonomous car. “Right now’s supercomputer-level techniques will run autonomous autos,” says Potter. 

Close to-term deliverables

Expertise from The Machine is being fed into HPE’s vary of servers. Potter says HPE has run large-scale graph analytics on the structure and is talking to monetary institutes about how the expertise may very well be utilized in monetary simulations, comparable to Monte Carlo simulations, for understanding the affect of danger.

Based on Potter, these can run 1,000 occasions sooner than in the present day’s simulations. In healthcare, for instance, he says it’s degenerative ailments, the place 1TB of information must be processed each three minutes. HPE is how one can transition complete chunks of the medical utility’s structure to The Machine to speed up knowledge processing.

From a product perspective, Potter says it’s accelerating its roadmap and plans to roll out extra emulation techniques over the subsequent yr. He says HPE has additionally labored with Microsoft to optimise SQL server for in-memory computing, in a bid to scale back latency.

Among the expertise from The Machine can also be discovering its method into HPE’s high-end server vary. “We’ve constructed optical expertise into our Synergy servers, and can evolve it over time,” he provides.

Right now, organisations construct huge scale-out techniques that cross knowledge out and in of reminiscence, which isn’t environment friendly. “The Machine will change many of those techniques and ship better scalability in a extra energy-efficient method,” concludes Potter.
