To-Do and Wish List
High Priority
- Cluster configuration file standard definition
- Adapting various clients (genmachines / threads) to make use of cluster definition file
- Add large (~1 TB) dataset with variety of modes on Data Fabric (CR)
- Synchronize data fabric test datasets at several sites. (Bonn, Curtin, NRAO)
- Regression testing scripts (AD)
Make general version of NRAO Monitoring GUI, with generic database backend (USNO)az/el in the calc file, + parallactic angle?- Amplitude correction for primary beam effects for multifield projects
- IPP alternatives
Medium Priority
- Choose framework for unit testing. Implement test cases (JM)
Certifying that non-power-of-2 FFTs worksvex2difx (or other) support for creating .machines and .threads (from the eVLBI perspective)- Add DiFX diagnostics
- Storing the original pointing source somewhere in the FITS file (plus the attendant AIPS changes)
DiFX with ASKAP data (CP)Add an option in startdifx to loop/wait for a module insertion if it is missing- Add per-IF phase polynomial in the calc file (and delay polynomial, too?)
- Documentation
- Doxygen of mpifxcorr source -
automatically installed locally, also someone mirror to a webserver Documentation of mpifxcorr internals (buffers etc.)
- Documentation Algorithms
parameter optimisation (AD)- monitoring, etc - (list of error codes) (AD) ⇒ LOW
setting up native Mark5 access (WB+)
- evlbi
- reconnection/long term drop-outs (CP)
- real-time delay/rate adjustment (CP)
- Maintain database of benchmarking results (JM)
- Phased array (RS, CR).
- visplot (CP, JS)
- Investigate sampler stats monitoring (AD/WB/CP)
- subband distribution/parallelisation (with VDIF) (AD/CP)
- replumbing/refactoring vex2difx setup
- Transition to using band centres instead of band edges (WB)
- Baseband data generator for producting test datasets. (WB)
- Parallelised calc server / Efficiency gains in CALC (same time, different sources etc)
- Store polynomial tau(l, m) generalized delay model in FITS (WB,JM)
Standard way of setting up environment (JM)Have different environments for building and operation (GC)- Chase up and eliminate the cause of occasional “Somehow Visibility X ended up with Y+1 subintegrations - was expecting only Y” errors
- Mixed module and file list on one station
Investigate whether changing maxReadSize to 8MB (or going to 8 MB subreads) fixes the Bonn problem
Low Priority
- Play back from both Mk5 banks in parallel (WB)
- vex2difx to create an input file setup to be used with vlbi_fake
- Complete Support for VDIF on module directories
- Refactoring the mpifxcorr/mk5daemon libraries and merging functionality
- Move to a binary format for pcal files and name by datastream not by antenna name
- vex2 support (relies on vex2 finalization and some support from field systems)
- On-the-fly application of calibration (bandpasses etc) with appropriate accountability
- Modernize sniffer
- cleanup of DiFX error messages
Single process multi-threaded non-mpi program for DiFX-specific CPU benchmarking.Future proofing via non-prescriptive format (AD)- K5 format support (CP)
- Space VLBI
Orbit model- Baseline dependent averaging
- eVLBI gui
- Generic startup scripts (CR)
- Documentation of startup philosophy
- Shifted FT (moving channel boundary to edge of band) (AD)
- DiFX2fits uv shifting in trunk (JM/AD)
Migrating to python3.0 (ensure current compatibility with python2.6) (everyone)Add support for crosscorrelation of non matching sample ratesSVN cleanup- Auditing / refactoring the amplitude scaling
- Pulsar predictor support in “polyco”
- Get rid of printing to screen in mark5access (change to be called and printed from elsewhere)
- Get Eric to improve AIPS PCAL (multi tone)
- Improve the runtime predictor (make better use of the new cluster configuration file, better estimate true load)
Review DiFX installation (SCONS, autotools etc.) (JM)- Restitching contiguous zoom bands into wider bands (e.g. for ALMA)
