Account

To help attributing the usage of computing resources to the groups and projects of AWI, which is needed for reporting, on Albedo it is necessary to specify an account.
This is done by setting

-A, --account=<account>


Possible slurm accounts are listed after login. To enforce setting an account, no (valid) default account is set.
Users are, however, able to change this setting on their own:

sacctmgr modify user <user> set DefaultAccount=<account>


The account specified is only used for reporting issues. No account gets privileged access to compute resources compared to others!

Partitions

Albedo’s compute nodes are divided into the following partitions, which are shown in the table below.

The smp partiton is the default and is for jobs with cores.

Nodes in the mpp partition are exclusively reserved. This partition is used when one ore more nodes are needed.

The fat nodes can be selected via the fat partition. This partition resembles the smp partition but each node has much more memory.

Similarly, the GPU nodes can be accessed via the gpu partition. Note, that the type and number of GPUs need to be specified. More infos about the hardware specification of each node can be found in the System Overview.

Description

smp

prod-[001-240]

  • default partition,

  • MaxNodes=1 → MaxCores=128,

  • Jobs can share a node

mpp

  • MaxNodes=240

fat

fat-00[1-4]

  • MaxNodes=1

  • Jobs can share a Node

gpu

gpu-00[1-2]

  • MaxNodes=1,

  • Jobs can share a node,

  • Note: You have to specify the type and number of GPUs --gpus=<GpuType>:<GpuNumber>

    • gpu-001: 2x a40
