Project Description

(HackWeek 24): Continue further.

(HackWeek 23): Started last hack week with some more work after that in free time. Started as experiment in describing the image and vector operations as C fragments and then using Tcl to generate all the boilerplate around that to link them to a runtime. Plus writing the runtime itself.

Internals inspired by VIPS. Got the planned multi-threaded operation done in the time after the hack week.

Things to do:

• More operations (always)
• Requires some kind of caching (in-memory, disk) for mismatches in native access. Examples
  • column FFT ask for column data from input, and input can provide only rows.
  • whole image operation is queried by a user for rows, tiles, etc.
• Record per-operator information about supported/fast access modes

Goal for this Hackweek

• At least one additional operation (code and tests)
• Progress on specification of a cache system
• Or progress on specification of access modes and how to combine them for a sink driving a pipeline

Resources

• https://core.tcl-lang.org/akupries/aktive/timeline (primary, fossil)
• https://github.com/andreas-kupries/aktive (secondary, git)

Note: Mirroring is unidirectional, from primary to secondary. Work can only happen in the primary.
