 The task of parallelization of imaging basically involves running multiple instances of nodeHandler which would launch different images on different nodes. The basic sequence of imaging of nodes as of now is as follows:

 The pxe service also provides a mean to set boot image for all the nodes at once with allSetBootImage? which is not working right now. Possibly its just a dummy query.

 In order to evaluate any performance issues, if occuring, while the nodes are being imaged in parallel a basic ping experiment was performed to calculate the RTT from the console to the individual nodes while the nodes were being imaged in parallel. Following are the results:
