The primary exascale supercomputer has a {hardware} failure each day


Briefly: Frontier, the arena’s maximum robust supercomputer, is on-line however nonetheless a long way from operational. Its director has showed studies that it’s experiencing a machine failure each and every few hours, however insists that is par for the route.

Frontier is in a category of its personal. It has 9,408 HPE Cray EX235a nodes, every powered by means of an AMD Trento 7A53 Epyc 64-core CPU supplied with 512 GB of DDR4, and 4 AMD Intuition MI250X GPUs / accelerators every supplied with 128 GB of HBM2e. Summed, the machine has 602,112 CPU cores and eight,138,240 GPU cores in overall, and four.6 PB of each DDR4 and HBM2e.

In Might, Frontier joined the TOP500 as the primary supercomputer to wreck the exascale barrier after it finished the HPL benchmark with a rating of one.102 ExaFlops/s. Since then, the Oak Ridge Nationwide Laboratory in Tennessee, which manages the supercomputer, has been readying it for clinical analysis scheduled to start out in January.

Alternatively, there were studies that the release of Frontier may well be waylaid by means of over the top {hardware} screw ups. In search of solutions, Inside of HPC arranged an interview with the Program Director at Oak Ridge, Justin Whitt. Within the interview, he showed Frontier was once experiencing day-to-day machine screw ups however asserted that was once inevitable in this sort of huge machine.

“Imply time between failure on a machine this dimension is hours, it is not days,” he stated. “So you want to be sure you perceive what the ones screw ups are and that there is no patterns to these screw ups that you want to be inquisitive about.” Whitt added that going an afternoon and not using a failure “could be remarkable.”

“Our objective remains to be hours.”

There have been rumors that the {hardware} issues had been being led to by means of the brand new AMD Intuition MI250X, however Whitt refuted them. The MI250X is AMD’s maximum robust GPU/accelerator, and it most effective sells it to make a choice companions. It has 220 CUs containing 14,080 cores clocked at 1700 MHz in a 500 W package deal.

“The problems span numerous other classes, the GPUs are only one,” Whitt remarked. “It is been a beautiful excellent unfold amongst commonplace culprits of portions screw ups which were a large a part of it. I don’t believe that at this level that we’ve got numerous worry over the AMD merchandise,” he added.

“We are coping with numerous the early-life roughly issues we have now noticed with different machines that we have now deployed, so it is not anything too out of the bizarre.”

Whitt conceded that the exceptional scale of Frontier had made effective tuning it “somewhat bit tougher” however stated they had been nonetheless following the time table set again in 2018-19 regardless of delays led to by means of the pandemic.
