sioan:

• has fpga hardware
• starting to use Herbst makefile
• sxrk4816 is on back burner (using absolute sz errors)
• continue to identify experiments where we can reduce

...

• working on DRP event distribution

sioan:

• vivado hls:  C-style programming done
• matlab is next

...

clemens:

• data in and out of pgp

Mar 28, 2017

sioan:

• still working on compiling hello-world
• still working on sxrk4816 with clemens

...

• explore the idea of keeping the data for a day

cpo:

• zhenglin results
• upcoming meetings with users

...

• beam centering: hough, ransac, scipy optimize 1-ring fitting
• canny uses soble filter
• looked at skbeam.  canny works better.
• hough transform took optimizing

chuck:

• playing around with SZ.  difficult because doesn't integrate into python.
• simulated SZ by adding 1% error
• sees common mode shift.  surprising, not understood
• indexing rate is 98% similar.  looks promising

...

• integrating silke's pyfai numbers from gpu onto his plots
• will work on legion
• next project:  work on the infrastructure for handing out events to different cores

mikhail:

• looked at skbeam centering algorithm
• sz compression

...

• working with legion people on gpu-based two-threshold lag

Feb 21, 2017

sioan:

• working on spatial.  good progress

...

• away at LBL xtallography workshop:  pessimistic about drp
  • unit-cell not known
  • bad pixels, which change over time (good enough, but room for improvement in our dark runs)
    • compare bad-pixel maps from super-users to dark-run results
  • geometry
• python scaling problem work
• students look at pywavelets:  zero-pads for performance reasons

Feb 14, 2017

Chuck:

• Tried SPI wavelet compression: 4x (on top of a 4x binned image)
• quantifying the error at goal: 3Angstrom resolution (currently 9nm)

...

sioan:

• running spatial builds

sioan:
possible users to contact:

...

• comparing python/C++: still working on it
• zmq/mpi/gasnet
• gasnet: 3 year old python bindings
• setup mtg with elliott/wonchan?
• talk with DAQ about DRP re-configuration

mikhail:

• henrik algorithm
• filipe maia algorithm
• running on gpus/knl
• evaluate compression package from argonne that amedeo will send out
