Hello!
I am creating this thread to comment on an issue raised today during the MIDAS
workshop.

The ROOT I/O workshop was held on June 20th at CERN. A few things of interest in MIDAS land:
- LZ4 is now used as default compression (replacing gzip-1)

15 Dec 2003, Pierre-André Amaudruz, , ROOT GUI at Triumf
|
The current Triumf DAQ standard (Midas) since the second quarter of this
year (2003) has the capability to deal with ROOT histograms. The internal
midas logger can save data files in ROOT format and the analyzer can book

The ROODY online histogram viewer and the ROOTANA midas analyzer toolkit have been updated to work
with ROOT version 5.16 and tested on Linux (SL4.4) and MacOS (10.4.10/PPC).

FWIW, I am running latest 32-bit MIDAS on an AM2 dual core AMD machine under 64-bit SL5. Everything
seems to work correctly. K.O.

23 Feb 2007, Konstantin Olchanski, Info, RFC- support for writing to removable hard disk storage
|
At triumf, we are developing a system to use removable hard drives to store data collected by midas
daq stations. The basic idea is to replace storage on 300 GB DLT tapes with storage on removable
esata, usb2 or firewire 750 GB hard drives.

We stopped using tapes at Los Alamos a while ago. The model we use is:
write data with mlogger to a local RAID system. This is NFS mounted read only on teh analysis machines, and

In the MEG experiment, we simply installed 100TB of RAID disks and don't need to change anything ;)
But seriously, you are right that such a system might be beneficial. I propose to extend the current logger code to switch disks. In the current tr_start() |

23 Feb 2007, Konstantin Olchanski, Info, RFC- history system improvements
|
While running the ALPHA experiment at CERN, we stressed and broke the MIDAS history system. We
generated about 0.5 GB of history data per day, and this killed the performance of the history plot
system in mhttpd - we had to wait for *minutes* to look at any plots of any variables.

26 Feb 2007, Stefan Ritt, Info, RFC- history system improvements
|
I agree to what you propose. I'm pretty sure you are right in getting a significant improvement in readout speed
of the history system. So far there was no big request for improving the history system, since the performance in
the experiments I was involved in was good. In MEG for example, we have ~20MB of history data per day, and all

After implementing 2 prototypes, one aspect of the new design is starting to firm up enough to write it down (I do so in a mock FAQ format).
