Hi,
I am writing shell scripts to create some tree structure in an ODB. When
creating an array of strings, the default length of each string element is 32

21 Apr 2005, Konstantin Olchanski, Suggestion, Correct MIDASSYS setting?
|
Current MIDAS versions nag me about setting the env.variable MIDASSYS to the
"midas installation directory", but I do not have one, so what should I set
MIDASSYS to? I checkout MIDAS from cvs into /home/olchansk/daq/midas, build it

Dear all,
I want to control (start / stop / monitor its stdout and stderr) an external process (systemd / EPICS IOC shell script) from within MIDAS.

Thanks a lot,

Hi,
unfortunately I don't have a documentation link to the feature, I just know that it works on my machine ;-) The general idea is that you place a custom |

Dear all,
Stefan wants to run an external EPICS driver process as a detached process and somehow "glue" it to midas to control it. Actually a
similar requirement led to the development of MIDAS in the '90s. We had too many configuration files lying around, to many process to control and interact |

become a midas process.

Dear Midas and Rootana people,
We have tried to update our midas DAQ with the new TID definitions describe in https://midas.triumf.ca/elog/Midas/1871

In the DEAP experiment, the normal MIDAS mlogger gzip compression is not fast enough for some data
taking modes, so I am doing tests of other compression programs. Here is the results.

I redid the tests from Konstantin for our MEG experiment at PSI. The event structure is different, so it
is interesting how the two different experiments compare. We have an event size of 2.4 MB and a trigger
rate of ~10 Hz, so we produce a raw data rate of 24 MB/sec. A typical run contains 2000 events, so has a

I tried to solve the problem by adding a ";". It was wrong. In fact, the macro "_syscall0(..)" doesn't need the ";".
I searched and found that somebody said "the overall _syscall$magicnumber will disappear". I don't mind whether the "_syscall" disappear or not. I just
want to compile the code and do my job. I deleted the additional ";" and recompiled. The error output is as the attachment [elog:335/1]. |
