D-tAcq Solutions using MDSplus segments for high speed long pulse data acquisition
Long pulse data capture with live update
- Continuous streaming data from digitizer to MDSplus
- 96ch x 500kHz = 96MB/s
- Streams to Linux host computer with MDSplus trees on SSD, 1000s.
- Live data plots with MDSplus and EPICS
- Continuous archive to MDSplus using long pulse extensions
The key tech behind this is:
- PCI-Express streaming interface
- SSD - fast disk drive
- MDSOBJECTS segmented put (C++ lib used)
- Use BIG segments (last year they were big, but not big enough)
- Partition the problem over multiple cores and subtrees.
