Re: [HTCondor-users] time of day policy

Hi,

I think anything request_.* triggers a condition: 

In the examples below, assume Tag is the custom resource name.

so
request_tag = <expression>

causes

RequestTag = <expression>

to be added to the job ClassAd, and the Requirements expression will have

 (TARGET.Tag >= RequestTag)

  or

 regexp(RequestTag, TARGET.TAG)

Anyway - I meant shutdowntime of course or remaining uptime :) 

I am currently experimenting with something like this: 

    /* Job must start outside restricted hours (before 11:00 or after 14:00) */
    ( (CurrentHour < 11) || (CurrentHour >= 14) ) &&
    /* If starting before 11:00, must finish before today's 11:00 */
    ( (CurrentHour < 11) ?
        (CurrentHour + floor(request_runtime / 3600) < 11)
        :
        /* If starting after 14:00, must not wrap into any future 11:00â14:00 window */
        (
            /* Calculate total runtime in full days + remaining hours */
            (floor((request_runtime / 3600) / 24) == 0) ||  /* If runtime < 24h, just check today */
            (
                /* For multi-day jobs, ensure no part of runtime overlaps 11:00â14:00 */
                ((CurrentHour + (request_runtime / 3600)) % 24 < 11) ||
                ((CurrentHour + (request_runtime / 3600)) % 24 >= 14)
            )
        )
    )
)

Will try it line for line and see but would still be interested to know if the clocktime feature includes runtime aspects ... 

best
christoph

 	I don't understand this question.  AFAIK, "request_runtime" isn't 
a thing -- at least, it doesn't appear to be in the manual.  I'm also not 
sure what the "uptime value" of the host is in the context -- the host's 
uptime (time since boot) shouldn't change any as a result of running or 
not-running jobs.
