 16 Jun 2021, Marco Francesconi, Info, 1000 Mbytes/sec through midas achieved!
|
As reported by Stefan, in MEG II we have very similar ethernet throughputs.
In total, we have 34 crates each with 32 DRS4 digitiser chips and a single 1 Gbps readout link through a Xilinx Zynq SoC.
The data arrives in push mode without any external intervention, the only throttling being an optional prescaling on the trigger rate.

I adapted our analyzer to compile against the manalyzer included in the midas repo.
All our data files are .mid.gz, which now fail to process :(

I had to add a 'umask' opiton to the loggers (lazy and mlogger) for the new
PSI archive. One can now put a filename into the settings like:

While executing "make install" under MacOS 10.4.7, you may encounter errors about "dio". It is the
problem of "Makefile". I did some change to it and attach the diff file here. |
