sioan:

• working on spatial.  good progress

clemens:

• found slowdown for python bin count:  memory copy due to bad types
• went through nersc presentation slides
• need to use the fast local ram on knl
• to do: how much does it cost to get 10GB/s through a node?
• working with timbvd on beam-position centering
• why is it hard to do in angular integrations in real-time?  detector corrections

mikhail:

• working on sz from argonne
• difficulty running examples, but fixed
• only runs on floats
• timing measurements for sz
• automatic centering algorithm in skbeam/xicam/silke's huff algorithm

chuck:

• 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

Chuck:

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