 You can change your allocation from the default using the **-c** = **--cpus-per-task**, **--exclusive**, **--mem**, and **--mem-per-cpu** options.
-If you use the "--exclusive" flag, slurm will allocate all cores on one node to your job, but unless otherwise specified it will still allocate the default of 8GB per core. This may not be all the memory available on the node that slurm allocates to you (e.g. on a node with 32 cores and 384GB of RAM, slurm would allocate 256GB of that RAM to you job). So, if you want a whole node you should probably use both "--exclusive" and "--mem=0" (which slurm treats as a request for all memory on a node).

 In the man pages, generally, **CPU==core** because of this configuration choice. For example, the **-c** option mentioned above has full name **--cpus-per-task** but really means cores per task in our configuration.
