CUDA-based event processing

Description

Explore the possibility of using CUDA-enabled hardware to do parallel processing on event lists, pixel-by-pixel. I am envisaging one algorithm that would handle several features at once (thereby minimizing back-and-forth memory transfer):

  • Histogram events pixel-by-pixel
  • Filter events (by wall-clock time, pulseID, others?)
  • Perform time-focussing

The algorithm could obviously do only part of this, i.e. histogram without filtering.

  • Priority changed from major to trivial

Interesting, but priority lower than scientific functionality requests

  • Milestone changed from Iteration 30 to Iteration 31

Bulk move of tickets to iteration 31 at the iteration 30 code freeze

  • Status changed from new to verify
  • Resolution set to duplicate

See Ticket #3635. OpenCL is more attractive than CUDA since it is not vendor-specific.
