 So far we understood that slurm chooses '_on which nodes our programs should run on_' based on it's scheduling decisions, however it also provides more control like specifying explicitly on which `partition` we can run our programs on.
 
 Here partitions are similar nodes grouped together as a list. For example H100 nodes are grouped together as a partition named `H100_Partition`. Whenever we submit a job request for H100s then nodes sequentially along this partition are reserved and our job is scheduled on them.
