 # Slurm Workload Manager
-[Slurm Workload Manager](https://slurm.schedmd.com/overview.html) is an open source [Job scheduler](https://en.wikipedia.org/wiki/Job_scheduler) that is intended to control background executed programs. These background executed programs are called **Jobs**. User defines the Job with various parameters that include run time, number of tasks (CPU cores), amount of required memory (RAM) and specify which program(s) to execute. These jobs are called batch jobs. (Batch) Jobs are submitted to common job queue (partition) that is shared by the other users and SLURM will execute the submitted jobs automatically in turn. After the job is completed (or error occurs) SLURM can optionally notify the user with email notification. Additionally to the batch jobs user can reserve compute node for interactive jobs where you wait for your turn in queue and on your turn you are put on your reserved node where you can execute commands. After the reserved time is over your sessions is terminated.

-### Slurm Partitions on sampo.uef.fi
+{{:guides:slurm:slurm.png}}
-- **serial**. 4 out of 4 nodes. Maximum run time 3 days
+## Slurm Partitions on kudos.uef.fi
-- **longrun**. 2 out of 4 nodes. Maximum run time 14 days
-- **parallel**. 2 of 4 nodes. Maximum run time 3 days.
-### Explanation of the partitions
+- **small**. 8 out of 10 nodes. Maximum run time 3 days
+- **longrun**. 3 out of 10 nodes. Maximum run time 14 days
+- **gpu**. 2 nodes. Maximum run time 3 days.
-Compute nodes are grouped in multiple partitions and each partition can be considered as a job queue. Partitions can have multiple constraints and restrictions. For example access for certain partitions can be limited by the user/group or the maximum running time can restricted.
+## Explanation of the partitions
-**Serial** partition is the default partition for all jobs that user submits. User can reserve maximum of 1 nodes for his/her job. Default run time is 5 minutes and maximum 3 days.
+Compute nodes are grouped into multiple partitions and each partition can be considered as a job queue. Partitions can have multiple constraints and restrictions. For example access to certain partitions can be limited by the user/group or the maximum running time can restricted.
-**Longrun** partition is for long running jobs and only one node is for this usage. Default run time 5 minutes and maximum 14 days.
+**small** partition is the default partition for all jobs that the user submits. The user can reserve maximum of 1 nodes for his/her job. Default run time is 5 minutes and maximum 3 days.
+**longrun** partition is for long running jobs and only one node is for this usage. Default run time 5 minutes and maximum 14 days.
+**gpu** partition is for gpu jobs (CUDA jobs). The user can reserve 2 nodes with 8xNVIDIA A100/40 GB. Default run time is 5 minutes and maximum 3 days.
-**Parallel** partition is for parallel jobs that can span over multiple nodes (MPI jobs for example). User can reserve 2 nodes (minimum and maximum). Default run time is 5 minutes and maximum 2 days.
