Could you please clarify on item 2, namely, the 4-hour-minimum rule?
If a write needs less than 4 hours, what is the procedure to initiate
a "share ride"?
As I understand it, the purpose of policy #2 is to ensure that one can
make reservation without being cutting off by other users. In the case
that we need less than 4 hours, can we simply reserve what we need
and let others know? It may be easier this way.
Thanks for your attention.

> Current RAITH 150 Reservations Policy:
> 1. Reservation limit of 8 hours per rolling 10 day reservation window on
> the Coral Reservation System.
> The reservation horizon was increased from 7 days to 10 days on Coral to
> allow you a longer window to make reservations.
> 2. Minimum of a four hour reservation slot, or you should 'Share the Ride'
> with other users within your CORAL reservation. i.e., No half hour
> reservation games allowed or tolerated! Not necessary to petition the
> Raith list for each of your sessions!
> 3. Longer reservation needed than the normal 8 hour session:
> You may have one reservation only of up to 10 hours maximum if you have no
> other reservations on the RAITH Coral system in a rolling two week period.
> You must have approval from James Conway if you desire a session longer
> than 10 hours, and you will then not be able to make an additional
> reservation for a two week period after that reserved session is
> completed. This is meant to meet the needs of users with special writing
> needs or circumstances only.
> 4. Reservations start (rather than end) within the reservation horizon.
> This change in particular, is designed to avoid the "30 minute roulette"
> that labmembers wishing to reserve the raith and the stsetch have been
> forced to play.
> <!--[endif]-->5. We have abandoned the concept of 'prime time' and
> 'non-prime time' hours. The Lab operates 24/7.
> 6. First Come First Serve -- You must use your reservation before making a
> new reservation on the Coral system.
> Raith System Usage Policy:
> 1. No System Usage Limit:
> While we have specific limits to RAITH Coral reservations, we do not have
> a limit on the system utilization if there are no other users working on
> or reserved for the system. I expect the system to be utilized 100% of
> the time. Users are asked to make the hand off between users as smooth as
> possible. It is suggested you check in with the previous user a short time
> before your session to aid in communications and the system hand off to
> reduce the unload / load exchange interval time.
> 2. Grace Period: Users are expected to start and end your writing sessions
> within 15 minutes of the scheduled time slot.
> If you are having problems, or encountered difficulties during your write,
> which may require for you to extend into the next user's session you are
> expected to make an attempt to inform the next user within a hour of the
> hand off time. You must gain their permission to extend into their
> session. If you don't get permission or cannot complete the EBL task --
> you are expected to cancel the exposure and immediately yield the system
> to the next user on their request. If you did not start your session on
> time as scheduled you will not be allowed a grace period to continue into
> the next person's session.
> Remember you must gain the next users permission to extend beyond 15
> minutes into the next reservation slot.
> 3. Beginning your writing session -- the '16 minute Rule' applies:
> If at 'minute 16' of your reservation slot, if you have neither shown up
> to start your session, nor marked the system with a note saying you are
> coming, nor communicated with the last user on the system and posted to
> the raith mailing list; you lose your entire reservation. It is only upon
> the courtesy of the user available to come onto the system, once he has
> enabled on CORAL for the session, as to either to return the system to you
> within your lost reservation time or not.
> 4. Cancellations:
> Cancellations and trade off in RAITH sessions should be posted to the
> Raith mailing list for all to view as soon as possible once you realize
> that you will not be able to make use of your reservation. It is expected
> of Users that cancellations be done at least 24 hours before your reserved
> session to allow other lab members to make use of the opening. <!--[if
> !supportLineBreakNewLine]-->You must post a reason for your cancellation,
> particularly if it was due to a system or machine dependence from within
> the lab not allowing you to get your work finished.
> 5. If there is no one on the system and no reservation on CORAL, the
> system is available to you for your use.
> This does not affect your reservation limits on the Coral schedule and
> there is no need to make a reservation on Coral for this session.
> 6. ALL USERS must enable CORAL in their own account for their writing
> sessions. At the time of enable Users are to start an entry in the RAITH
> Operations Logbook and all pertinent information should be recorded.
> Problems during a run should be reported to CORAL and noted in the Logbook

> Thank you for your inputs and support of these policies. This should go a
