Re: [Condor-users] quoting of globusrsl string ?

[Siegfried Goericke <sgoericke@xxxxxxxxxx>]

THX a lot, it works with this quoting and a "big" globusrsl string.


but it is possible to expand a macro or var in the rsl string before the 
rsl string passed to the remote condor?

for instance I have two condor pools and and must pass the names of the 
input files correctly

in condor-G(only one executable ==> only one cluster): 
transfer_input_files = in.$(process) 

the file staged in correctly pool1: in.0, in.1    pool2: in.3, in.4

but in the rsl string I have the problem to pass the correct 
transfer_input_files and argument statement to the remote condor?

THX for any ideas. 



Mit freundlichen Grüßen/kind regards
Siegfried Göricke

Ahhhhhh! Multiple levels of quoting and variable substitution. Getting it
right is a nightmare. Let's see what we can do....

Sad that this can't work. The combination of Condor-G not knowing what the
remote local scheduler is, having to stage the executable before it's
submitted to the remote local scheduler, and Globus renaming staged
executables to "data" make it unworkable.

You've also tripped over our crude hack to discover what version of GRAM
is on the server, because Condor-G is expecting any $$ to be expanded
locally via matchmaking before submitting to Globus.

As you found out, Requirements is only used locally. If you were to set up
matchmaking to find what globus resource to use, you'd use Requirements
and Rank for that.

Here, you need to get your multi-level quoting right. First, you need to
put backslashes in front of each double-quote to make condor_submit happy.
It takes the entire string, slaps double-quotes around it, and shoves it
into the job classad, without trying to escape the double-quotes in the
string first. Then, you need to put single quotes around the entire
requirements expression, since parentheses, ampersands, and quotes have
special meaning in Globus RSL syntax. Condor-G treats GlobusRSL as an
opaque string that it slaps on the end of the RSL it builds to submit to
Globus.
