mikhail:

• looked at skbeam centering algorithm
• sz compression

silke:

• try SZ compression on some XPP/XCS datasets

sioan:

• try SZ compression on some SXR/AMO dataset (works trivially with georgi's dataset)
• spatial FPGA code working

clemens:

• angular integrations: background is not symmetric (scattering from masks etc).  take difference of t0 (no signal) and later data (with signal) and that is symmetric and allows determination of beam center.  beam centers changes every half-hour so calibrations would have to be quick.
• have results for CPU/KNL
• found benchmark of EPICS common-mode correction, found performance problem in ndarray.
• looked at intel vtune

chuck:

• wavelet stuff takes 3ms on 250x250 image with pywt
• visually physics results look OK

chris:

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

sioan:

• working on spatial.  good progress
