Ryan sent an email to digital asking about possible workarounds that would allow current guppi_daq to be used with LBW pulsar modes. Still waiting on response
Ryan will send a reminder email and meet face-to-face if necessary after the Thanksgiving holiday.
VE-336: Troubleshoot high time resolution modes
Natalia is doing a comparison of S/N in each bank with some old data.
Natalia analyzed some old data and was able to partially recover the noise diode signal. The levels were low in some banks and Ryan wants to get more data with better vegas.scale values.
Ryan is working on getting some more data in RAW mode for Natalia to analyze. He has been trying to get data in the 32 channel modes if possible. This has been slowed by other testing.
VE-341: Test Matrix Classic for release
Biggest issue is that managers do not conform new parameters when switching between modes if those managers were not already in use.
Switcover works when configuring manually
Joe and Ray are adding a conform in the config tool for VEGAS manager to emulate manual behavior
Ray is working on functions to program the 10-gig core directly instead of going through the borph server. This should prevent ARP storms from banks that are not in use and fix issues with MAC addresses
Hoping to have some of these in place for testing over Thanksgiving
VE-339: Identify directory to install user tools
Joe and Ray will create a repo for Ryan to use
VE-348: Work on VEGAS Matrix documentation
Joe did some work on this. Has a developers document started. Set aside to work on more pressing issues.
VE-350: Test 32-channel modes
Incoherent modes seem to be working
Coherent modes have a different packet size than higher channel modes
Joe sent Luke binary and decryped packet data
Joe verified that the counter field is present and incrementing properly
Luke sent a follow-up email identifiying which fields are missing
These fields could be filled with dummy values so that packets are the correct size
VE-349: Support testing
Joe and Ray have been supporting testing
VE-351: Support Yunan testing
Visit is over. Seems to have gone well.
VE-345: Focus on deploying classic HBW pulsar and spectral line Matrix
Testing is ongoing.
VE-346: Bundle software for Yunan
VE-347: Change latency list
Luke sent Ryan a preliminary summary. Ryan waiting on more information.
VE-331: Continue troubleshooting packet loss issue in c1500 modes
Joe thinks some of this will go away by deactivating ROACH's and getting ARP tables set properly.
VE-322: Cannot validate scripts offline
No update yet.
VEGAS Pulsar Project Meeting - Sprint Planning: 2017 October 23rd 2:00 - 3:00pm ET
Note: The team's "velocity" has been consistent at 11--13 points per sprint. We should aim for 12 points per sprint for planning purposes.
Ryan will test over Thanksgiving shutdown. Goal is to do a test of all spectral line modes with both total power and frequency switching, and all pulsar modes with various scalings. If Joe and Ray's upcoming work is ready, Ryan will also test handoff between different modes.
Operator will leave L-Band in focus and Ryan in the gateway. Ryan will be online at shutdown to verify that he has proper permissions.
Ray and/or Joe will switch software versions before 9:00 PM on Wednesday.
Ryan will do overnight testing on Wednesay and Thursday morning. Will be done before noon Thursday.
Ryan will send Ray and Joe and email to tell them when they are done, and they will switch back to release by 6:00 AM Friday morning.
Ryan will be on Talk and Draw for the end of shutdown to make sure there are no lingering issues.
High time resolution modes
Investigate packet loss in c1500 modes
Continue work on Matrix LBW pulsar modes
Offline script validation
MAC addresses for 10-gig ethernet ports are wrong for Banks C and D in VPM coherent modes
Identify a source tree for VPM utilities
Install VPM utilities in new source tree
Add a Task Master task for vpm_auto_plot, automatic VPM bandpass monitor, and a DAQ server used to monitor processes on the VPM HPCs in coherent dedispersion modes.
