Whole nodes are allocated. Use `--nodes` option to specify number of requested nodes.
There is no need to specify the number of cores and memory size.
```console
#!/usr/bin/bash
#SBATCH --job-name MyJobName
#SBATCH --account PROJECT-ID
#SBATCH --partition qcpu
#SBATCH --time 2:00:00
#SBATCH --time 12:00:00
#SBATCH --nodes 8

## Using GPU Queues
Access [GPU accelerated nodes][5].
Every GPU accelerated node is divided into 8 fractions, one fraction per GPU.
By default only one fraction i.e. 1/8 of the node - one GPU and corresponding CPU cores and memory is allocated.
There is no need to specify the number of cores and memory size, on the contrary, it is undesirable.
```console
#!/usr/bin/bash
#SBATCH --job-name MyJobName
#SBATCH --account PROJECT-ID
#SBATCH --partition qgpu
#SBATCH --time 12:00:00
...
```
## Using Fat Queue
Access [data analytics node aka fat][6].
Fat node is divided into 32 fractions, one fraction per CPU. By default only one fraction i.e. 1/32 of the node - one CPU and corresponding memory is allocated.
