Re: [Condor-users] Help with ClassAd syntax: offset $(process) [SEC=UNCLASSIFIED]

["Lenou, Peter (Contractor)" <Peter.Lenou@xxxxxxxxxxxxxxxxxxx>]

UNCLASSIFIED

Thanks Kevin.

I have tried $$([Process + 1]) and it doesn't replace anything. I even
tried $$([TARGET.Memory * 0.9]) as in the example and it doesn't replace
anything. Maybe it only works with Arguments and not TransferInputFiles.

Peter

Are you sure the syntax is

  $$([$(process)+1])

The example in the manual says

  The syntax appears as:

  $$([ClassAd expression])

and the example given is:

  In the submit description file will be

  arguments=--memory $$([TARGET.Memory * 0.9])

suggesting that, if it can be done, you should be using:

  $$([Process + 1])

without the extra $() around Process.

My other suggestion would be to create a parallel directory of links to
the input files where the link names match what you appear to need and
the link target matches what a program that could handle "start from 0"
would just use without issue.


I should say that I have not tried either of the above.
