The NIG Supercomputer
Grid Engine Queue Type
This is an old document
This document is a former NIG supercomputer (2019) document and is kept for reference purposes.
Please note that it does not work in the same way on the current NIG supercomputer (2025).
Compute nodes managed by the Grid Engine are broadly devided into interactive nodes and compute nodes.
- interactive nodes(interactive node) are calculators to develop users' programs or perform small, quick calculations interactively on the spot.
- Compute nodes(compute node) are compute node to perform calculations that take a long time or use a large amount of CPU or memory.
Compute requests called jobs to login and compute nodes are managed in Grid Engine with queues. Jobs wait in queue and are automatically executed by Grid Engine as soon as a computer is available if calculation requirements exceed computer resources.
In the general analysis division of the NIG supercomputer, there is a Grid Engine queue for each type of compute node.
