Re: [ptp-dev] PTP RM commands and proxy events

I have a question and a couple suggestions 
When the resource manager sends commands to the proxy, it expects 
asynchronous responses. Does this allow for multiple commands to be in 
progress with responses pending? Does the design allow for commands where 
you must get a reponse before proceding because you need some information 
from the proxy, such as a list of available nodes, or is it up to the 
implementor to deal with that?

For resource manager commands, additional commands that might be useful 
include commands to query node availability, query resource pools, query 
job classes, query job queues, query what's running on the machine, what's 
running on nodes, change job priority, cancel pending jobs (vs killing a 
running job), disconnect from and reconnect to proxy. If the proxy is 
expected to inform the resource manager of the complete state of the 
machine, queues, etc, at startup, some of these queries might not be 
required.

There's probably some additional commands required to initiate an 
application under debugger control since the proxy may need to do extra 
work in that case.

For events the proxy sends to the resource manager, again, I don't see 
anything missing, but additions would be needed as responses to the 
additional resource manager commands I suggested.

[ptp-dev] PTP RM commands and proxy events






I've completed a rough draft of the notes I took yesterday regarding 
commands initiated by the resource manager (RM) and events sent back 
by the proxy agents.  It is on our wiki at:

http://wiki.eclipse.org/index.php/PTP/designs/rm_proxy#Proxy_Events

Comments/changes welcome.  It will probably change as we begin to 
implement and test the protocol.

Happy Holidays,
Craig
