Interview: Mark Potter, CTO, HPE

The Machine is the biggest analysis and improvement programme in HPE’s historical past. Its objective 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 methods have been engineered to cache often used knowledge and retailer older knowledge on disk – however with reminiscence being a lot cheaper at present, maybe all knowledge could possibly be saved in-memory reasonably than on disk.

By eliminating the inefficiencies of how reminiscence, storage and processors presently work together in conventional methods, 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 Pc 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 got scaled the system 20 instances,” he says. The Machine is now working 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 are able to 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, similar to splitting gentle into a number of wavelengths, could possibly be used sooner or later to additional improve the velocity of communications between reminiscence and processor.

Trendy laptop methods are engineered in a extremely distributed trend, with huge arrays of CPU cores. However, whereas we’ve got taken benefit of elevated processing energy, Potter says knowledge bandwidth has not grown as shortly.

As such, the bottleneck in computational energy is now restricted by how briskly knowledge could 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 got unveiled could 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 could possibly be utilized to construct a high-performance computer (HPC), similar to an exaflop-scale supercomputer.

The Machine could possibly be many instances 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 at present, which devour 650MW of energy,” says Potter. “Our objective is an exaflop system that may obtain the identical compute energy as the highest 500 supercomputers whereas consuming 30 instances much less energy.”

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

“We’re digitising our analogue world. The quantity of information continues to double yearly. We won’t be able 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 have to be accomplished remotely, on the level the place knowledge is collected.

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

One of many traits in computing is that high-end expertise ultimately leads to commodity merchandise. A smartphone most likely has extra computational energy than a classic supercomputer. So Potter believes it’s fully 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.

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

It could be harmful and unacceptable to expertise any form of delay when computing safety-critical choices in actual time, similar to for processing sensor knowledge from an autonomous automobile. “Right now’s supercomputer-level methods will run autonomous autos,” 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 talking to monetary institutes about how the expertise could possibly be utilized in monetary simulations, similar to Monte Carlo simulations, for understanding the affect of threat.

In keeping with Potter, these can run 1,000 instances quicker than at present’s simulations. In healthcare, for instance, he says it’s taking a look at degenerative ailments, the place 1TB of information must be processed each three minutes. HPE is taking a look at find out how to transition entire chunks of the medical software’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 methods over the following 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. “Now we have constructed optical expertise into our Synergy servers, and can evolve it over time,” he provides.

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