Another milestone has been reached: Our new supercomputer Arrhenius has undergone the acceptance test and is now formally transferred from HPE to NAISS. In the HPL tests, which measure the system’s floating point computing power, Arrhenius was clocked at 66.8 petaflops.

“We are preparing to start allocating resources on Arrhenius from June,” says NAISS Deputy Technical Director and Arrhenius Project Manager Gert Svensson.
