RPC and Daemon

• KestrelHPC uses a rpc server written in python for event handling. Each event is passed to kestrel-daemon through a FIFO.
• KestrelHPC daemon is written in bash script, reads events and their parameters from the FIFO and calls event.d scripts using the function run_register_scripts located in kestrel-lib.
• KestrelHPC's library (kestrel-lib). Most of the functionality is implemented here.

Configuration variables

Variables get their default value form these configuration files located at :

• Default config file : /usr/share/kestrel/default.conf
• Default config file of each module : /usr/share/kestrel/default.d/*

/usr/share/kestrel/* should not be modified by a user because they will be overriden when a package is updated. They should modify /etc/kestrel/kestrel.conf instead.

Event scripts

• Event scripts. There scripts are executed when an event ocurrs (register/unregister/connect/disconnect).

Node scripts

• Node install scripts. These scripts are executed when an image is created or deleted.
• Node packages. Packages to install on the images.
• Node post-install scripts. These scripts are executed when an image is created or deleted, after installing the packages.
• Node configure scripts. These scripts are executed when the user reconfigures the system.

Frontend scripts

• Frontend configure scripts. These scripts are executed when the user reconfigures the system.
