Chuck:

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

Mikhail:

• looking at igor/matt compression
• much faster than gzip, but limit is 2x compression
• igor used multi-threading, matt did not
• to do: enter igor stuff in spreadsheet, work on argonne package

silke:

• work on pyfai
• ran on  gpu102
• compared with henrik bincount method
• csr ocl is 4x as fast 1x henrik code, their numpy version is very slow (30x slower than henrik's)
• turn it into a metric

clemens:

• benchmarking phi
• python is 8x worse than C
• to do: test at SLAC and test with matrix multiply
• to do: run all corrections and see if we can get 10GB/s

sioan:

• running spatial builds
