[Moabusers] error: unknown attribute

[Josh Butikofer]

Sandeep,

The '$PBS-W x=' line is being inserted by Moab before the job is submitted to PBSPro. This attribute 
is called an RM extension string and it is used by Moab to keep track of information pertinent to 
grid jobs. This type of RM extension string is supported by TORQUE, but is not supported by
PBSPro. Older versions of PBSPro (5.x, 6.x, etc.) would silently ignore this line, but the new 
PBSPro 7.x seems to complain and reject the job.

Instead of using extension strings, Moab is supposed to use "custom resources" to attach the 
necessary information to grid jobs. The syntax is almost identical. If you are running PBSPro, Moab 
should detect this and insert:

#PBS -l x=SID:santosh;SJID:santosh.134;SRMJID:Moab.50

Notice the "-l" replaces the "-W" in the previous example.

A custom resource named "x" would also need to be defined in the "server_priv/resourcedef" file. 
(Just add a line with only "x" on it at the bottom of the file and then restart pbs_server.)

It appears, however, that your version of Moab is not using the PBSPro compliant syntax when 
submitting jobs and is therefore causing problems. If you switch the "-W" to a "-l" and add the "x" 
to the "server_priv/resourcedef" file will the job submit successfully?

If this works we still need to determine why Moab is not doing this change automatically. We can 
diagnose this with you and get you a fix if there is something awry in Moab.

Regards,
