Available batch job partitions
The following partitions (aka queues) are currently available in Puhti for normal (CPU) nodes:
|test||15 minutes||80||2||M||382 GiB|
|interactive||7 days||4||1||IO||64 GiB||640 GiB|
|small||3 days||40||1||M, L, IO||382 GiB||3600 GiB|
|large||3 days||1040||26||M, L, IO||382 Gib||3600 GiB|
|longrun||14 days||40||1||M, L, IO||382 GiB||3600 GiB|
|hugemem||3 days||160||4||XL, BM||1534 GiB|
|hugemem_longrun||7 days||40||1||XL, BM||1534 GiB|
The following partitions are available on GPU nodes. Note that for each GPU, you should reserve at most 10 cores/task.
local storage (nvme)
|gputest||15 minutes||8||2||GPU||382 GiB||3600 GiB|
|gpu||3 days||80||20||GPU||382 GiB||3600 GiB|

Notes on partitions
- Only request the memory you need
- The jobs will run sooner, since in each partition, most of the nodes have less memory than the maximum amount
- Billing is based on memory requested, not on memory used
- Only use longrun partitions if necessary
- These partitions have stricter limits and a lower priority
- Only one job per user is allowed in interactive partition
- Use this partition with the command sinteractive.
The following partitions (aka queues) are currently available in Mahti:
|large||20-200||36 hours||scalability test|
|gc||200-700||36 hours||Grand Challenge|
Interactive partition, is intended for pre- and post processing tasks. It can be used both for interactive working and in batch jobs, where reserving a full node is not reasonable.
The actual HPC computing should be done in medium, large or gc partitions. Only full nodes are allocated from these partitions and the jobs will have access to all cores and memory in the nodes. You may choose to run with fewer cores if that gives better performance. In these partitions billing is based on the allocated nodes.
The large partition on Mahti is only accessible to projects that have done a scalability test and shown good utilisation of the resources. The partition gc is only accessible to Grand Challenge projects and allows users to run extremely large simulations.
