Interview: Mark Potter, CTO, HPE

The Machine is the most important analysis and improvement 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 continuously used knowledge and retailer older knowledge on disk – however with reminiscence being a lot cheaper immediately, maybe all knowledge may very well be saved in-memory reasonably 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 scale 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 Laptop Weekly, Mark Potter, chief expertise officer (CTO) at HPE and director of Hewlett Packard Labs, describes The Machine as an entirely new computing paradigm.

“Over the previous three months we’ve 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, corresponding 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 style, with huge arrays of CPU cores. However, whereas we’ve 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 consider memory-driven computing is the answer to maneuver the expertise business ahead in a means that may allow developments throughout all elements of society,” says Potter. “The structure we’ve unveiled will be utilized to each computing class – from clever edge units 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), corresponding to an exaflop-scale supercomputer.

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

“An exaflop system would obtain the equal compute energy of all the highest 500 supercomputers immediately, which eat 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 immediately, however utilizing a fraction of energy of a contemporary supercomputer, that Potter believes can be wanted to assist the subsequent wave of internet of things (IoT) purposes.

“We’re digitising our analogue world. The quantity of knowledge 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 selections 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 developments in computing is that high-end expertise ultimately leads to commodity merchandise. A smartphone in all probability 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 regionally.

Contemplate machine studying and real-time processing in safety-critical purposes. “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 will be harmful and unacceptable to expertise any sort of delay when computing safety-critical selections in actual time, corresponding to for processing sensor knowledge from an autonomous automobile. “As we speak’s supercomputer-level techniques will run autonomous automobiles,” says Potter. 

Close to-term deliverables

Know-how 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 chatting with monetary institutes about how the expertise may very well be utilized in monetary simulations, corresponding to Monte Carlo simulations, for understanding the impression of danger.

Based on Potter, these can run 1,000 occasions quicker than immediately’s simulations. In healthcare, for instance, he says it’s degenerative ailments, the place 1TB of knowledge must be processed each three minutes. HPE is how one can transition entire 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.

A few of the expertise from The Machine can be discovering its means into HPE’s high-end server vary. “We now have constructed optical expertise into our Synergy servers, and can evolve it over time,” he provides.

As we speak, organisations construct large scale-out techniques that go knowledge out and in of reminiscence, which isn’t environment friendly. “The Machine will exchange many of those techniques and ship higher scalability in a extra energy-efficient means,” concludes Potter.
