Feedback needed: Obsolete options and parameters considered for removal

Posted by chris Tue, 24 Jun 2008 12:22:41 GMT

Grid Engine developers posted a list today of SGE configuration parameters and client arguments that are being considered for removal from the product because they are either obsolete or they duplicate settings found elsewhere.

The developers are seeking feedback and comments on their plans - if you have any please drop a line to the users@gridengine.sunsource.net mailing list. The current roadmap calls for these methods to be marked as 'deprecated' in the SGE 6.2 release with total removal planned for a future post-6.2 release.

The message can be found here:

The full list of items being considered for removal can also be found after the jump ... 

The parameters planned to obsolete are:

host_conf(5)
- processors
   obsolete, same as num_proc from the complex list

sched_conf(5)
- algorithm
   just default is allowed, no additional algorithms are planed
- params JC_FILTER
   huge performance impact plus may lead to wrong scheduling decisions

sge_conf(5)
- reprioritize
   redundant because hard bound to reprioritize_interval in sched_conf(5)
- shell_start_mode
   obsolete, value from queue_conf(5) is used
- set_token_cmd
   no known AFS support
- pag_cmd
   no known AFS support
- token_extend_time
   no known AFS support
- qmaster_params DISABLE_AUTO_RESCHEDULING
   equivalent to default reschedule_unknown=0:0:0
- qmaster_params merge ACCT_RESERVED_USAGE and SHARETREE_RESERVED_USAGE
   We can't imaging a use case to have these values separated
- finished_jobs
   qstat -j does not work with successful finished jobs. Code seems
   to work only with jobs going into error state.

user(5)
- delete_time
   change to internal, not changeable/visible field
   Implicit set by auto_user_delete_time

qconf(1)
- sep option
   obsolete, same as num_proc
- ks option
   obsolete, same as -kt scheduler

qmod(1)
- c option
   depreciated, use -cj or -cq
- r option
   depreciated, use -rj or -rq
- s option
   depreciated, use -sj or -sq
- us option
   depreciated, use -usj or -usq
