Re: [HTCondor-users] passing parametric values to transfer_input_files

[John M Knoeller <johnkn@xxxxxxxxxxx>]

That depends on what $(args) expands to.  You can use any classad _expression_ with $STRING () in a submit file. so something like this...

MY_SCRIPT = <_expression_>("$(args)")

transfer_input_files = this,that,$STRING(MY_SCRIPT)

Where <_expression_> can use classad functions, replace, split & join.  join turns a list into a string, while split turns a string into a list.  so, for instance

MY_SCRIPT = join(",", split("$(args)"))

will change spaces between items to commas, so if 

   args = a b c

$STRING will evaluate to a,b,c and thus transfer_input_files will be

   transfer_input_files = this,that,a,b,c

Conversely.  you can formulate the items as bare list that you transform both into args and into a file transfer sublist

# submit statements

args = -file $STRING(args_from_items)

transfer_input_files = this,that,$STRING(files_from_Items)

# turn "a b c" into   "a -file b -file c"

args_from_items = join(" -file ", split("$(items)"))
# turn "a b c" into "a,b,c"

files_from_items = join(",", split("$(items)"))

queue items from {

  a b c

  d e f

}

Subject: [HTCondor-users] passing parametric values to transfer_input_files

 

Hi all,

I'm using as last line of condor submit file:

queue args from somefile.txt

and I would like to specify something like:

transfer_input_files = this,that,MY_SCRIPT($(args))

where MY_SCRIPT($(args)) evaluates to: surl_1,surl_2,...,surl_x

Note that <x> is not necessarily the same number for every line in
somefile.txt
Is something like that doable?

Thanks
Stefano
