 On NeSI, GPU's are specialised pieces of hardware that you request in addition to your CPUs and memory.
 
 You can find an up-to-date(ish) list of GPUs available on NeSI in our [Support Documentation](https://docs.nesi.org.nz/Scientific_Computing/The_NeSI_High_Performance_Computers/Available_GPUs_on_NeSI/)

-| Name | Other Names | Slurm Option | Pros/cons |
-| - | - | - | - |
-| Shared Memory Parallelism | Multithreading, Multiproccessing | `--cpus-per-task` | Efficient, Can only be as large as one node |
-| Distrubuted Memory Parallelism | MPI, OpenMPI |  `--ntasks` and add `srun` before command | Can run across multiple nodes,  communication overheads |
-| Hybrid | | `--ntasks` and `--cpus-per-task` and add `srun` before command | Best of both SMP and DMP, More complex |
-| Job Array | | `--array` | Best throughput and efficiency, Requires embarrassingly paralell work  |
-| General Purpose GPU | | `--gpus-per-node`  | Very fast, Requires code written for GPUs |

 Requesting extra resources through Slurm only means that more resources will be available, it does not guarantee your program will be able to make use of them.
