[ptp-dev] About PTP's support for resource manager

["jiangyangtz" <yangtzj@xxxxxxxxxxx>]

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
