[Condor-users] question about job requirement

["Hao Liu" <guzi5618@xxxxxxxxx>]

Dear All,

A simple question just popped up in my head:
when a user submit a job, how does he specify/know the requirements
(such as Requirements   = Memory >= 32 && OpSys == "SOLARIS28" && Arch
=="SUN4u"  )?  How does user know OpSys == "LINUX" is not eligible for
this job?
Does the user have to some tests for running the job before submitting
to condor?

And how is the resource requirments related to a job?  Do you guys
have a specific example to explain why sometime a job can only run on
a particular type of computers ? Many thanks

Regards,


Hao
