 ## Using CPU Queues
 
+Access [standard compute nodes][4].
+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.

+#!/usr/bin/bash

-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.
