Agenda
Status and Tasks
Julien
- Status
- Defined role of experiments and batches
- Working Batchmake Dashboards and graphs
- To-dos
- Implement BMDashboards
- Sun is reporting the wrong physical memory
- Appropriate summary statistics
- Per machine: batch -vs- speed/error
- Per test: mflops -vs- speed/error
- All, batch -vs- % change in performance
Brad
- Status
- Commit into CVS
- Implement as ctests
- Continuing to develop registration pipelines
- Optimize the meansquareddifferenceimagetoimagemetric
- To-dos
- Send email/data to Kilian and determine his runtime on the data
- Time function?
- Get parameters from Kilian
- Define deformable registration test that matches Kilian's
- Get binaries of the program that Kilian is using
- Run our tests on Kilian's machine
- Send email/data to Kilian and determine his runtime on the data
Seb
- Status
- Setup BatchMake Dashboard
- Setup NAC/BWHItkOptimized Dashboard
- Work with Julien on Batchboard designs
- To-Dos
- Work with Julien on Batchboard designs
- Investigate other opportunities for optimization
- Improve/de-chicken Stephen's macro
Stephen
- Status
- Continue to optimize MattesMIMetric
- Determine BMDashboard table structure
- Generate cmake macro for defining metric tests
- MattesMI_GetValue, MattesMI_GetDerivative, MattesMI_GetValueAndDerivative
- MI_GetValue, ... (no optimized version yet)
- Command line arguments
- -u : perform unoptimized tests only
- -o : perform optimized tests only
- -v : compute value tests only (for metrics only)
- -d : compute derivative tests only (for metrics only)
- -c : compute combined (value and derivative) tests only (for metrics only)
- Submit grant proposal
- To-Dos
- Continue to optimize MattesMIMetric
- Generate cmake macro for defining transform and interpolator tests
- Move multi-threading to itkOptMultiThreadedImageToImageMetric.h/txx
- Subsampling, masks, and multi-threaded
