Re: [HTCondor-users] Job Transform

[John M Knoeller <johnkn@xxxxxxxxxxx>]

Hmm.  I would expect this to work.

   SET Requirements (OpSysAndVer == "$(OpSysAndVer)") && $(tmp.require)

The Schedd should have OpSysAndVer defined automatically so the $() expansion should work there

try running this command,  what is the output?

    condor_config_val -v -schedd -dump OPSYS

The output should have OPSYS and OPSYSANDVER and some other matches as well.

This bit 

    EVALMACRO tmp.require = unparse(Requirements)

isn't necessary though.  You can just do this 

JOB_TRANSFORM_MatchOS @=end
   SET Requirements (OpSysAndVer == "$(OPSYSANDVER)") && $(My.Requirements)
@end

$(My.Requirements)  in a job transform should expand to the current value of the job's unparsed Requirements expression.

Subject: [HTCondor-users] Job Transform

After a bit of debugging, I came up with a job transform that would add 
a requirement that the OS name and version on the schedd and startd match:



JOB_TRANSFORM_NAMES = $(JOB_TRANSFORM_NAMES),MatchOS

JOB_TRANSFORM_MatchOS @=end
EVALMACRO tmp.require = unparse(Requirements)
SET Requirements (OpSysAndVer == "Rocky8") && $(tmp.require)
@end



My question is How can I dynamically populate the OS/Ver field instead 
of hardcoding 'Rocky8'?  I tried a couple of permutations, both of which 
evaluated to an empty string when I submitted a test job:


JOB_TRANSFORM_MatchOS @=end
EVALMACRO tmp.require = unparse(Requirements)
SET Requirements (OpSysAndVer == "$(OpSysAndVer)") && $(tmp.require)
@end


JOB_TRANSFORM_MatchOS @=end
EVALMACRO tmp.require = unparse(Requirements)
EVALMACRO tmp.myos = unparse(OpSysAndVer)
SET Requirements (OpSysAndVer == "$(tmp.myos)") && $(tmp.require)
@end


Is there another way to accomplish this?
