TGBT15A_915_141 - Test Packet Loss in Long Coherent Search-Mode Scans Again
Goals
* On two occasions observers have reported excessive packet loss during coherent search mode observations with VEGAS and GUPPI in dual backend mode (800 MHz bandwidth, 512 channels). This does not seem to occur when using only one or the other. One past attempt to recreate this was unsuccessful but we will try again.Details
- Session begins at ????
- Submitting CoherentModeTestsSearch _LongScan SB. Will end at 15:15
- KEEP RECORD OF SCANS HERE
Conclusions
- WHAT HAPPENED
- NOTE: DATA CAN BE DELETED FROM /lustre/gbtdata/TGBT15A_915_141/VEGAS_CODD/[A-H] AND THE GUPPI GPU NODES FROM /data/gpu/partial/gpu[{1..9} (MUST LOG INTO THE INDIVIDUAL NODES). DON'T DELETE THE WRONG STUFF!!!!
