Software iPlatform ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],p.

Software iPlatform : General setup p. Partition 1  SANET jobs Partition 2  iNode jobs /tmp/log on iNode automaticly saved to log/job_run/nodeId on NFS share

Software iPlatform : Intended usage ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],p.

Software iPlatform: Files needed for experiment p. Program files start_mount_code: This script is automatically started after booting. You can start your own software by calling it in this script vmlinuz: Custom linux kernel initrd.img: Custom drivers log directory: Automatically created, contains content of /tmp/log directory of iNodes

Software iPlatform : concept p. Inode 1 Inode 2 Inode 3 Inode 4 Master Slaves 1.2.3.4:/master_code/ 1.2.3.4:/slave_code/ An iPlatform defines for all iNodes in w-iLab.t which user code will run on which iNode Inode 5 Inode 6 Inode 7 Not used

Software iPlatform : Policy ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],p.
