Arrhenius clears acceptance test, benchmarked at 66.8 PFLOPS

Another Arrhenius milestone was reached last week. After a successful acceptance test, the system has now been formally transferred from HPE to NAISS.

“On the whole, I would say that the test went very well. Now we can finally put Arrhenius into operation,” says Gert Svensson, NAISS Deputy Technical Director and Arrhenius Project Manager.

The acceptance test has several parts. Everything is being scrutinised to ensure that it is delivered and installed according to specifications. Various benchmarks are run using large scientific applications and synthetic tests to measure power consumption, network speeds, and other properties.

The benchmark also includes so-called HPL (High-Performance Linpack) tests to measure the system’s floating point computing power for the TOP500 list of the world’s most powerful supercomputers. Arrhenius reached a score of 66.8 PFLOPS. The formal ranking will not be settled until June when the next top list is compiled.

“That is a very good score,” Gert Svensson concludes.

The next step is to install dedicated software, set up the system for production, and open it to users. In May, a few selected experienced test users will be the first to try out the system with real jobs.

“We are preparing to start allocating resources on Arrhenius from June. Our aim is to open the system for general use by then.”

NAISS users on the old Tetralith and Alvis systems will be the first to migrate. In the second phase, during the autumn, Dardel users will also be transferred, and the Sensitive data partition will come online, welcoming both new and Bianca users.
