[gin-jobs] Worker Node Environment

[Aleksandr Konstantinov]

  Dear Laurence,


 Many statements in a draft are clearly non-applicable to some execution
environements - some of them are not even grid-related. Hence it would be 
nice to have some tags like MUST, SHALL, etc. assigned to every item and 
action to be taken in case of absence of those items.
 Purpose/usage of defined items would be also nice to have. That would help
to understand what is expected that item to represent.

 Here are some items with meaning not clear to me:

 GRID_SITE_ID - what is "site"?
 GRID_GLOBAL_JOB_ID - at Grid level job may have multiple IDs. Should it 
be one known to initial client or last one known during job's submission 
to batch system? Or list of them?
 GRID_VO_ID - there may be job's (and users) unrelated to any VO. Should 
there be some generic VO name? Or some ad-hoc name? Or VO per user?
 GRID_APPLICATION_ROOT - what is "application software"?
 HOME - what if jobs are not assigned any home-like environement?
 GRID_CLUSTER_HOME - what if there is no "home" shared among cluster's nodes?
Same goes for GRID_GLOBAL_HOME, GRID_CLUSTER_SCRATCH and GRID_GLOBAL_SCRATCH.
Since those locations are shared, their access protocol is most probably 
nor POSIX. What is format of associated value, URL?
 GRID_HOME_TYPE - why enumerated? What about exotic file systems?

 Why bootstraping scripts location includes VO name at all? How about software
shared among VOs? Used by non-VO users? Is there any namespace planned to 
distinguish between different softwares with same name?


A.K.
