**The access priorities for two availability slots are suggested as:**
** “****Special” user access, ****priority order**** - limited number of projects**
** ****Pu-aging continuing scope out - projects designated by Nielsen, Chadwick**
** ****SSP science scope out - access managed by Steve Louis (LLNL)**
** ****LLNL meeting in spring or early summer to kick off tri-lab planning**
** ****Pit aging, turbulence, HE, etc.**
**3. “Short” Gordon-Bell runs - access managed by Steve Louis (LLNL)**
**  ****Early user access, ****priority order**** ****- ******** 6 months**
** ****Pu-aging unclassified program work (as defined in Pu-aging plan)**
** ****SSP science unclassified program work (as defined in SSP science plan) **
** “****Q-like” science competition**
** ****Maybe 3 or 4 projects, including at least one Alliance, maybe other external**
** ****32,000 to 64,000 node calculations for perhaps up to 1 week for each project**

**“****Special” user access**

**“****Early” user access”**

**Notes:**
- I added the word "order" to each access period to emphasize that the lists are very much a priority ordering.- I changed the word "special" to "restricted" as Steve suggests, to lower general expectations.- I added Gordon Bell as the the third item in the restricted user access period because for SC2005, the runs have to happen here.I think that work at all three priority levels needs to also be prioritized within a category because unexpected difficulties will arise that can reduce the available time.   Jean should just say this during her presentation, because the slide is already pretty full.If I understand correctly, the "marquee apps" are part of the acceptance test, and should be run as part of the yellow times that are off limits to all other users.  After all, we now have better codes to feature.
