I am sure everybody else has 10gige and 40gige networks and are sending terabytes of data before breakfast.
Myself, I only have one computer with a 10gige network link and sufficient number of daq boards to fill

In MEG II we also kind of achieved this rate. Marco F. will post an entry soon to describe the details. There is only one thing
I want to mention, which is our network switch. Instead of an expensive high-grade switch, we chose a cheap "Chinese" high-grade
switch. We have "rack switches", which are collector switch for each rack receiving up to 10 x 1GBit inputs, and outputting 1 x

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've seen that a similar question has been asked in 2011 but I'll ask again in
case there are any updates. Is there any way to write 64-bit data words to MIDAS
banks (other than breaking them up in to two 32-bit words, such as 2 DWORDs)

Hi,
I've been doing some preliminary work to use at least the MIDAS

I recently needed to watch the Midas messages for a particular error - and
thus needed a command to "get all the messages since a time t".

Dear MIDAS people,
I need to borrow your wisdom for a bit.
I am developing a piece of software that should read the history data stored in a

I guess all three options would work. I just tried mhist and it still works with the "FILE" history
mhist -e <equipment name> -v <variable name> -h 10
