Psana

  • New analysis package xtcav with code written by Alvaro Sanchez-Gonzalez with some help from Christopher O'Grady
  • PSShmemInput V00-01-01: Reduce queue depth in DgramSourceShmem from 32 to 3.  This is because shmem applications want minimal latency, which requires minimal buffering (at the expense of potentially more dropped events).
  • Add support for Epix100a
    • psana_examples V00-04-22: DumpEpix.cpp - add support for new types Psana::Epix::Config100aV1 and Psana::Epix::ElementV2 (see PSAS-7)
    • ImgAlgos V00-03-66: EpixNDArrProducer - add support for Epix::ElementV2 and Epix::Config100aV1 (see PSAS-7)
    • CalibManager V00-00-67: ConfigParametersForApp, ConfigFileGenerator add support for Epix100a (see PSAS-6, PSAS-7)

Bugs fixed

  • pypsalg V00-00-07: Throttle warning messages in find_blobs.py. Fix missing imports and add 2D histogram in Histogram.py.
  • psmon V00-01-04: Fix from Dan that prevents psplot from "falling behind" when ZMQ buffers on the client (display side) fill up.
  • PSXtcInput V00-15-06: Fix a bug in the indexing access to calibcycle times: multiple streams' calibcycles were being included in the list. To avoid duplicates, reduced it to just one stream's calibcycles (since they are all identical).

Known Issues

  • Python applications using h5py with parallel HDF5 would hang when exiting. Apparently, there is a deadlock caused by either mpi4py or h5py implementations. We're looking at this problem.
