 10 Oct 2005, Stefan Ritt, Info, Bus drivers moved in repository

The previous midas/drivers/bus dirctory contains both midas slow control bus drivers plus vme & fastbus & camac drivers. I separated them now in different
directories:

I manage to access some vme modules with the older vmicvme interface and seemed
confused with the
new interface as the sample code provided does not have a specific test sample.

02 Dec 2005, Greg Hackman, Info, MIDAS on Cygwin
|
If you want to run MIDAS on Cygwin, make sure you have cygserver running. First set a Windows system environment variable CYGWIN=server. This is best
done through the Control Panel -> System -> Advanced -> Environment Variables. Then run /usr/bin/cygserver-config in a Cygwin console window. Then reboot.
After that your MIDAS executables should run properly.

22 Dec 2005, Konstantin Olchanski, Info, midas max event size?

My TPC events are fairly large: 18 FEC cards * 128 channels per card * 2 Kbytes
per channel = about 4 Mbytes. In my
frontend, when I request this event size, MIDAS complaints (in mfe.c) that it is

It turns out the the standard event builder fragment matching algorithm cannot
be used in my TPC application. I have two TPC-USB interfaces, which lack any
"busy" or synchronization logic. I send the hardware trigger into both

At DANCE we have a similar issue. We are still doing "software
handshaking" between multiple frontends (15 which read data, and 16th
with direct accessto the trigger logic), and we apply a time stamp

13 Jun 2006, Stefan Ritt, Info, ZLIB dependency modified
|
Due to recent problems with the ROME analyzer having zlib.h both in the
system and in the midas tree it has been decided to change the zlib policy in midas. By default, zlib support is not included in the midas analyzer. If
one want it (but I guess only very few experiments need that), one can do a

13 Jun 2006, Stefan Ritt, Info, Scheduler changed for slow control equipment
|
The schedule in mfe.c is used both for "normal" front-ends and for "slow-control" front-ends. Unfortunately it was only optimized for the first class. This
lead to the fact that the slow control equipment was read out at different speed depending if the run is started or not. Furthermore, the maximum readout
speed was somehow limited. This has been changed in the current version of mfe.c (SVN revision 3146). There are now two ways to control the readout speed |

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.

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.
