Kargo and VMdeploy
Christine Morin, Christine.Morin@irisa.fr
Version V1.0 (experimental)
Kargois a shell script to deploy Kerrighed on cluster nodes. Based on a diskless approach, the script first deploys the master node that hosts the root image (NFSRoot) of the slaves nodes. After this it boots the slaves nodes in the new environment from the NFS root. VMdeployis a shell script that deploys VMware virtual machines on the Grid'5000 platform, allowing the users to run their scripts into virtual machines. The framework reserves the nodes, deploys a customized environment (with VMware server installed) with the help of Kadeploy, and then instantiates the virtual machines on the reserved nodes. VMdeploy is able to reserve nodes either as soon as possible (interactive) or when resources are idle (best effort). To avoid wasting resources due to the direct killing of best effort jobs by the OAR scheduler, the framework is able to automatically and transparently preempt/restart and migrate best effort jobs  ,  .
