There will be a 4 hour long service break on Mahti from Monday September 5 at 9:00 to September 5 at 13:00. During the service break there will be no access to the system, including login nodes and storage system.

During this service break the interconnect firmwares will be updated. These updates should make the network more stable also for large and MPI intensive simulations.

Jobs that can finish before the break will execute normally, and any jobs that are queuing when the service break starts will be able to run after it has finished.
