Re: [ptp-dev] Re: About PTP's support for resource manager
|
To expand a little more: Randy is still in the process of designing
the API that will be used to communicate between Ecllipse and the RM.
He will be putting an initial design document on the wiki soon. This
is meant to be an evolving process, so we would encourage you to
comment on the design and appreciate any changes or suggestions you
might want to make.

Jie Jiang,
What you described, that job submission and control can be affected
totally through the RM system, is what we are designing. We are
currently not at the stage that we have an API specified for someone
to hook-up their own RM, but we hope to have one soon -- my current
task. In fact SLURM is on our short list for targeting as our first
implementation, with LSF also in consideration.
About ORTE's future, we envision that even ORTE jobs will be handled
through the RM interface, an RM specifically for submitting,
monitoring, and controlling ORTE jobs.
The overall architecture will include the ability to instantiate
several RM's within an Eclipse session, each one could be of a
different type, e.g. SLURM or LSF, and each may be running on
different
remote sites. You would have a "currently selected" RM to designate
with which RM you would submit, monitor and control jobs.
Aside: Are you volunteering to implement the SLURM RM?

Randy

Hi all,
Currently, PTP runtime subsystem ultilizes ORTE to lauch, monitor
and control parallel jobs, processes and also obtain status about
computing nodes.However, there exist some other practical third
party's
resource management systems, such as SLURM, that can also lauch
process,
monitor process/node status. Their functionalities are similar to
ORTE,
but the implementations are different.Further, by now ORTE is not
widely used
and some users ultilize SLURM to manage the available computing
resources.
It's really necessary to make PTPsupport other RM system(like SLURM).
Fortunately, PTP team has realized this problem and Randy has been
working on this issue.
Here I'd like to know how to integrate RM support into PTP. That
is, can the PTP's
RM support subsystem compeltely substitue ORTE for RM users?
Since both can provide same funciotns to the upper UI layer,
does the PTP's RM subsystem has equal role as the current ORTE
subsystem ?
If so, the SLURM user can only rely on the existing RM to run PTP,
not
relying on ORTE anymore.
Best regards,
Jie Jiang
