next week's meeting.

Notes:

- Coordinate Transformations -- =
Maurik -- PDF =
FILE** Notes from =
meeting:
- It seems it would be =
nice to use the LAB frame for everything. This would avoid confusion =
about the coordinate system we are in. It would make things easier when =
dealing with survey data etc.
- The =
rotations involved seem relatively simple, but we have no clear idea of =
how much work would be really involved in the lcsim framework to get =
this done. *** Tracking =
currently has the magnetic field "hard wired" in the z =
direction.
- The hits would need to =
be rotated from LAB frame to SLIC frame.
- Not clear how much the multiple scattering and such =
would complicate this.
- Decision on this item will be postponed until we get =
some input from Norman, Jeremy and Rich.
- The alternative is to do all the geometry and tracking =
on the SLIC frame, and then rotate the resulting physics vectors to the =
LAB frame before writing out a DST.
- CED -- All
We should discuss and then vote on whether we want to =
encourage Dave Heddle to invest some time into creating an HPS version =
of his Event Display system. If we decide we want this, someone needs to =
sit down and hammer out what/how we want things =
displayed.** Notes from =
meeting:- Everyone agreed that =
CED12 seems a very useful program. All are in favor of encouraging Dave =
Heddle to create a version of this code for HPS.
- Matt will present some ideas on how we would like the =
tracker hits to be displayed for this program.
- Clara -- All
We=
never decided one way or another on the Clara system. This is probably =
not for the test run, but if it is something we want for the full HPS =
run, we need to decide on this soon.** Notes from meeting:- It =
appears that the CLARA framework may help in the problem of distributing =
the data over a large number of nodes, something we need for the Level 3 =
trigger.
- It is not clear how exactly =
the CLARA framework would be implemented for =
HPS. *** Some thoughts: Vardan =
would be providing some wrappers for the existing lcsim code. Specific =
blocks of lcsim would be implemented as a CLARA service.
- Key to successful implementation is identifying the =
code blocks to turn into a service and the communication required =
between these services.
- This =
is again something were we would need Norman, Jeremy and Rich to =
comment.
- Omar will look into =
CLARA to see if it can be useful for the Level 3 =
trigger.
- Merging Events -- =
Matt** Matt showed us some code =
that will merge many 2ns simulated events into longer events, allowing =
for a negative offset. This looks promising for us to get long pulse =
trains.
- Maurik remarked that =
he tried something like this, using a rolling buffer where for each next =
event to be analyzed, one new event is popped onto the buffer, one is =
dropped and all the other events are rolled by one slot. This is =
efficient in that you do not "waste" MC events. In the case of a trigger =
the buffer is flusher. However, it turned out that it becomes rather =
difficult to get the statistics correct.
- A similar problem would be if you randomly mixed the =
events. You would need to be very careful not to use the same event =
(which may cause a trigger) in the trigger window =
twice.
