The Cluster Management Software (OpenNebula) assumes that a HyperVisor is running on the machines which it is monitoring, it communicates with this HyperVisor to send and receive information about the node. text/html 2021-12-09T16:42:46+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.chpc.ac.za/playground:for_this_project?rev=1639060966&do=diff For this project we attempt a high resolution smoothed hydrodynamical simulation (SPH) and attempt to visualize the simulation. However a simulated particle requires very high resolution usually a single simulated particle would be of orders of tens of Millions Solar masses. For that reason one needs very fast and efficient computing hence the need for CHPC. To perform the simulations we use the freely available code for cosmological N-body/SPH simulations called text/html 2021-12-09T16:42:46+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.chpc.ac.za/playground:gadgetgallery?rev=1639060966&do=diff This page is a gallery of some of the Gadget simulations we ran at the CHPC.

Before doing anything it is recommended that you create an installation directory (e.g installations) on your /export/home/username/ directory. This will help you avoid any super user conflicts. For the rest of this walkthrough I will refer to /export/home/username/installations/ as PATHINSTALL. text/html 2021-12-09T16:42:46+00:00 Anonymous (anonymous@undisclosed.example.com) https://wiki.chpc.ac.za/playground:here?rev=1639060966&do=diff The plan is to use the Carlson and White (2012) approach to remapping a simulated cube to make a“pencil beam” cuboid from which we will cut the vuvuzela volume that will be observed in, for example, the LADUMA survey planned for the MeerKAT.
