SUMMARY:Ptychography with Extreme Data
DESCRIPTION:Maik Kahnt (MAX IV Laboratory, Lund University)\n\nX-ray micro
 scopy via ptychographic imaging has been growing rapidly in the last decad
 e. Where early experiments could only be performed by a few experts groups
  with their own specialized software implementations. Nowadays ptychograph
 ic experiments can be performed at plenty of beamlines and various open so
 urce software packages are being used and refined by collaborations across
  singular groups. With the increased availability and wide spread applicat
 ion of X-ray ptychography the initial challenge of "making it work robustl
 y" has been overcome. New challenges are all connected to every users wish
  to image more, meaning faster as well as larger samples. \nOn the experim
 ental level these wishes are being address by pushing towards beamlines wi
 th more photons that utilize bigger and faster detectors. On the data reco
 nstruction end this push towards more and more extreme data pushes the imp
 lementation of the reconstruction algorithms to their limits. Hardware arc
 hitecture, suitable algorithm design an implementation start to dictate wh
 at datasets can and can not be reconstructed. In this talk the problem of 
 "extreme data" in ptychography is dissected, current computation limits ar
 e explore and various ideas from the community on tackling these issues ar
 e presented and discussed.\n\nDomain: Chemistry and Materials, Engineering
 , Life Sciences, Physics, Computational Methods and Applied Mathematics\n\
