1) Although the tests are passed a list of nodes, not all tests limit themselves by it. This is a problem that needs to be fixed.
2) In the future, the proc count should be reported by NEST to ODA instead of pulled from the node anyway.
3) NEST should also write state to ODA on shutdown and startup. This also eliminates the need for any slow, global poll.

Hello,
In the "Complete cluster installation", the number of processors for each node is collected. However, this is a very slow process, especially on large cluster (128 nodes+).
I wonder why c3 is not used at this point. A command like cexec "cat /proc/cpuinfo | grep -E "^processor"|wc -l"
would produce the same result but it is much more faster than the one used because it uses c3 (then the result has to be parsed!).
Why are we doing a node to node ssh instead of using c3 directly ?
Another interesting thing to do would be to mark the non responding nodes as "dead" and remove them from the config files while keeping their configuration in the database ?
At least, we can use this list as the node list for the tests ?
