There are currently two problems from Grid Engine: - There seems no way for getting the desired NOW behavior (at least in this section the *optional* NOW keyword is not defined) for an GE specific enhancement, without breaking compatibility - In GE there is no currently no sliding windows support for the SET/SET/SET in case of duration is shorter than endTime-startTime (GE DRMAA implementation have then a similar problem then the other DRM which do not support NOW as startTime) Following suggestions for this section (5.6.2): - Add the *optional* "NOW" constant -> if an implementation does not support it, it is treated like UNSET (InvalidAttributeException) - If startTime, endTime and duration is set and duration is shorter than endTime-startTime, the sliding windows approach (take "the earliest point in time") could made optional. That means: take startTime and duration or *optionally* search the earliest point in time. I know we discussed it more than once, but having these options would make it much easier to get a compatible implementation. Cheers, Daniel Am 27.04.2011 um 23:46 schrieb Peter Tröger:
Line 751 - Reservation without time frame - Makes no sense, since it might be way too short for the user -> raise invalid argument exception on UNSET/UNSET/UNSET - add rationale why startTime=UNSET is not equal to startTime=NOW - handy concept supported by some, but not all DRM systems - Emulation in the DRMAA library is not a valid option, since this would lead to situations were the reservation already arrives 'too late' in the DRM system
