44 +==== BrainScaleS-2: "Job error" in the Collaboratory, though it worked until 21 June 2021 ====
45 +
46 +On 21 June 2021 we changed the platform selection in the nmpi command client.submit_job(...,platform=nmpi.BRAINSCALES,...). From then on, please specify nmpi.BRAINSCALES**2** as the platform to run networks on the BrainScaleS-2 architecture (i.e. on "wafer">60).

48 +In the JobManager, a job with the now wrong platform=nmpi.BRAINSCALES shown in the "log" part of the detailed job information:

50 +{{{72 is not a valid wafer module for BrainScaleS-1. Since 21 June 2021, please use "nmpi.BRAINSCALES2" as platform specification ...}}}

52 +Also since 21 June 2021 a separate quota setting is used for BrainScaleS-2 (visible on the Quota tab in the JobManager)

55 +
56 +Currently (2 July 2021) the default-system ("wafer 33") is under maintenance. Please see the [[BrainScaleS-1 chat>>https://chat.bioai.eu/external-users/channels/brainscales]] for updates.
