john i thank you for the encouragement. its better then what i get form certain people i deal with in ubuntu channels. you mention diskless booting using tftp and pxe. the problem though arises when u have a certain number of nodes accessing the same disk simultaneously where disk I/O shoots through the roof.<br>
<br>only reason i know this i was helping a professor the 2 yrs that i was in college in the usa before transferring we were creating a small cluster 1 head node and 4 slaves. all diskless. its nice thing to have but one thing that puts me off it is the idea of bogging down the drive. in the case of diskless would it be better then to go to a SSD on the head node?<br>
