Data Challenge Status
Curtis has started writing a report on the recently completed data challenge. There are still a lot of sections to be filled in.
Dmitry gave a report:
- The DANA library of sim-recon now requires CCDB to build. CCDB is still optional however.
- David has updated HDGeant and mcsmear use the new DANA (the DApplication class in particular).
- The code has been tested on MacOs
- It has also been tested with the clang compiler.
- The next release, ccdb-0.07, is in preparation.
- It will include the use of Resources to handle large files like the magnetic field.
- There is still a problem on CentOS 5 that Mark and Dmitry are chasing down.
New CPU architecture from Intel
David gave us an introduction to a new technology from Intel, the Xeon Phi MIC. This is Intel's answer to the recent popularity of GPU's for large-scale computations. See his talk for details. The outline:
- Some System Details
- Performance using JANA TestSpeed Plugin
Study of the board is just starting.
JANA Resources update
David gave us and update on the work he presented last November. See his slides for details. He has incorporated features that we discussed at the initial presentation.
