Minutes

Present: Elliott W, Simon T, David L, Carl T, Beni Z, Hovanes E.


ROC Purchase

Dave Abbott and Glenn Young are preparing a lab-wide purchase of single board computers, most likely a mix of dual-core and quad-core processors. Dave says boards from any of the three vendors who responded to the RFI should work fine, and that cost can be the deciding factor. Hovanes and Elliott will work out how many of each we need. Note that we currently have 11 dual-core processors of a previous generation, but they should be adequate for crates that don't have high-speed requirements. We are leaning towards quad-core for all the high-speed DAQ crates and duals for most of the remainder.


JInventory and Barcode Readers

Hovanes and Elliott met with a salesman. He recommended readers that act exactly as keyboard inputs, i.e. scanning a label does the same thing as typing the code on the keyboard. This simplifies web programming. We can get wireless (~$2k) and USB (~$200) scanners. The 1-D code readers have better resolution than 2-D readers, and the latter cannot read some standard labels, so we plan to go with 1-D readers (same cost, different sensor). Pre-printed labels are not expensive, small ones are about $175 for 10,000 labels, a lifetime supply for us. The salesman will lend us (and CLAS) a wireless reader to play with in the next week or two.


EVIO

Carl described recent improvements to the EVIO package, mainly driven by CLAS12 needs. In Java and C he implemented random-access I/O and append mode, Elliott has to implement these in C++.


Counting House

Hovanes described recent work in the counting house, including plans to install the UPS RDC cabinet and progress on the Rack Room wiring plan. Our techs will install the wiring and Paul Powers will perform inspections. One question is what to do about UPS power for the L3 farm if it indeed requires 2000 cores...the current UPS probably cannot handle it.


12GEV Project

With the reviews over Elliott and Dave are finally getting back to the planning documents.


Elog

Rumor has it that Accelerator has a prototype that the halls can look at. The new version was developed with hall requirements in mind.


cMsg GUI

Graham has a prototype XML-driven GUI that connects items in the GUI to cMsg subjects and handles all the I/O. With it you can write a program that talks to hardware, then connect it to a GUI without doing any GUI programming. Demo soon...


Solenoid

Elliott has been tasked with developing a FastTrack schedule for the solenoid test. He needs to upgrade FastTrack on voldemort. He will incorporate everything Tim, Josh and he already has.
