qinzeng peng | Forum | rpc timeout, related to event_size and watch dog? need help | Dear all,
I'm trying to write a simulation code on midas. What I did is just modify the
frontend.c(pp) from experiment samples and made some parameters change on midas.h .
Because my simulation ask for about 4.5MB for each event, so I increase the
MAX_EVENT_SIZE and max_event_size accordingly.
in midas.h :
#define MAX_EVENT_SIZE 0xa00000 //0x400000 /**< maximum event size 4MB*/
#define BANKLIST_MAX 640 //64 /**< max # of banks in event */
#define DEFAULT_RPC_TIMEOUT 60000 //10000
#define WATCHDOG_INTERVAL 5000 //1000
#define DEFAULT_WATCHDOG_TIMEOUT 60000 /**< Watchdog */
in frontend.cpp :
BOOL frontend_call_loop = TRUE;
INT max_event_size = 5 * 1024 * 1024;
INT max_event_size_frag = 2* max_event_size;
INT event_buffer_size = 2 * max_event_size;
EQUIPMENT equipment[] = {
{"WFD_SIMU", /* equipment name */
{1, 0, /* event ID, trigger mask */
"SYSTEM", /* event buffer */
#ifdef USE_INT
EQ_INTERRUPT, /* equipment type */
#else
EQ_POLLED, /* equipment type */
#endif
LAM_SOURCE(0, 0xFFFFFF), /* event source crate 0, all stations */
"MIDAS", /* format */
TRUE, /* enabled */
RO_RUNNING, // | /* read only when running */
// RO_ODB, /* and update ODB */
5000, /* poll for 500ms */
0, /* stop run after this event limit */
0, /* number of sub events */
0, /* don't log history */
"", "", "",},
read_simu_event, /* readout routine */
},
......
}
INT frontend_loop()
{
/* if frontend_call_loop is true, this routine gets called when
the frontend is idle or once between every event */
ss_sleep(100);
return SUCCESS;
}
Compilation OK and running mlogger, odbedit, frontend is OK.
start the run -> no problem ( but there is a long waiting time in frontend if
starting the run. Before the run begins, frontend terminal popping up messages
frequently, say, every 10 seconds. When run starts, frontend terminal hang on
for a couple of minutes before popping up next bunch of messages.)
stop the run -> Problem -> rpc timeout
message from odbedit:

Stefan Ritt | Forum | rpc timeout, related to event_size and watch dog? need help | Most likely you changed the maximal event size in midas.h, but you did not re-compile all programs. The maximal event size goes into the size of the shared memory buffer, so all participating programs have to have the same setting, especially the mserver program. So do the following:
- update to the latest midas version, which is revision 4116
- modify in your midas.h only MAX_EVENT_SIZE. The other settings you modified might have bad side effects. If you increase the RPC timeout, the error will still happen, just later. It comes from the fact that you sent too big events the the server (or the logger), which refuses to take the big events or simply crashes, so the RPC call never returns and after the timeout you get the error.
- recompile all midas programs, don't forget the mserver program
- run the standard demo frontend from the distribution
I tried the above and it just worked fine for me. |

Every time I changed midas.h or system header files, I did the re-compile with following procedure:
ipcrm
rm .*.SHM
mcleanup
make clean
make
su
make install

Question here:
How to compile mserver seperately? I think make and make install under midas directory already did the job.
| Stefan Ritt wrote: | | update to the latest midas version, which is revision 4116 |
I used latest svn version, so I believe I'm using the latest version 4116.
svn co svn+ssh://svn@savannah.psi.ch/afs/psi.ch/project/meg/svn/midas/trunk midas
svn co svn+ssh://svn@savannah.psi.ch/afs/psi.ch/project/meg/svn/mxml/trunk mxml
I followed your instructions and did the following:
1)
svn co svn+ssh://svn@savannah.psi.ch/afs/psi.ch/project/meg/svn/midas/trunk midas
svn co svn+ssh://svn@savannah.psi.ch/afs/psi.ch/project/meg/svn/mxml/trunk mxml
2)
changed two parameters in midas.h
#define MAX_EVENT_SIZE 0xa00000 //0x400000 /**< maximum event size 4MB->10MB*/
#define BANKLIST_MAX 640 //64 /**< max # of banks in event, I need 356 */
3) make
su
make install
I don't know if I need compile mserver seperately.
4) running only two programs:
odbedit -s 10000000
./frontend
And I still got the same problem as before.
[qzpeng@phy2-dhcp140 simu]$ odbedit -s 10000000
[local:simu:S]/>ls

And I know that the run stopped after a while on frontend, but after the eroor message showed above. If I tried to stop again in odb after a while, it did stopped.
[local:simu:R]/>stop
Run #1 stopped
By the way, thanks for the quick response. I've been working on this for a couple of weeks and I am a newbie.
I also attached my frontend.cpp code and output of make with warning message but comilation completed. Thanks in advance.
In frontend.cpp I only use simulation and don't need any hardware realted issue or function calls but I jsut leave some of them there. |

Stefan Ritt | Forum | rpc timeout, related to event_size and watch dog? need help | First of all, I would appreciate if you do not post your entry ten times. Each time you edit it, you produce an email notification going to everybody, so people might get annoyed to receive too many emails from you. Think what you want to write and then post once.
Second, I told you to use the frontend from the distribution, but you used your own code. Since I successfully ran the demo frontend with the large event size, the origin of your problem must be "in between". So start with the demo frontend, try it, then modify its buffer size in frontend.c, then try again. When I told to to recompile midas, I meant you should also recompile your front-end each time you change midas.h. The mserver is automatically recompiled when you recompile and install midas (just check the /usr/local/bin/mserver date and time to confirm that it got updated during your last "make install"). Then add things from your specific front-end program step by step to see at which step the problem occurs the first time. This gives you some hint where the real cause lies. |

Jimmy Ngai | Forum | CAEN VME-USE Bridge with MIDAS | Hi All,
I am testing the libraries provided by CAEN with the sample softwares in the
bundle CD. The Windows sample program works fine, but I cannot get started with
the Linux sample program. When I run CAENVMEDemo in Scientific Linux 5.1, it
gives me a message "Error opening the device". I have followed the instructions
in CAENVMElibReadme.txt:
- compile and load the device driver v1718.ko
- install the library libCAENVME.so
Does anyone have any experience of using V1718 in Scientific Linux? Thanks.
Regards,
Jimmy

Jimmy Ngai | Forum | CAEN V792N QDC with MIDAS | Dear All,
I have a problem when testing the V792N 16 CH QDC with the V1718 VME-USB
Bridge on Scientific Linux 5.1 i386 (kernel 2.6.18-53.1.21.e15).
The problem is that the V792N does not response normally after a few minutes
of continuous polling and readout of data. It seems like the V792N is hanged
and a hardware reset of the VME system is required to bring it working again.
If I do not poll for DREADY first and directly read the Output Buffer
continuously, the system can work properly.
I have worked on this problem many days but I cannot find any clues to solve
it. I have tried to use the CAENVMEDemo program (with some modifications) to
do the same thing (polling and readout) and it works fine. CAEN technical
support also doesn't know why the VME system is hanged. I think it might be a
problem of MIDAS itself. I have tried with MIDAS revision 4132 and the trunk
version, but the problem is still there. Is there any parameter in MIDAS
(buffer size etc?) which may cause this problem? I have attached my frontend
code and drivers for your reference.
Thank you for your kind attention.
Best Regards,
Jimmy |

Randolf Pohl | Forum | Mixed CAMAC/VME frontend, SIS3100 | Dear MIDAS-addicts,
I would like to hear your opinion on this:
We've until now used CAMAC with Hytec 1331 controllers. We're using Yale FADCs
whose readout takes ages in CAMAC (2048 samples take 2 milliseconds to be
read). We've got 20+ FADC channels (we usually read only 2-3)
Now we've had the brilliant idea to replace the Yale FADCs with some VME
digitizer and we now plan to buy a Struck SIS 1100/3100 PCI-VME controller,
plus 4 pc. CAEN 1720 8ch 12bit, 250MHz WFD.
(1) Can anybody comment on this choice? Good experiences/problems?
We are still using the CAMAC stuff for all other modules (TDCs, ADCs,
scalers). So my plan is to have ONE frontend who reads both the CAMAC modules
and the VME modules.
(2) Is it possible to build and run a dual-controller frontend for both CAMAC
and VME? Does anybody have experience with that? Or is it a stupid idea?
I'd appreciate any hints.
[Edit: We're using Linux]
Thanks a lot,
Randolf |

Dear Randolf,
I used some time ago several HYTEC 1331 controllers together with the Struck
SIS3100. Since the HYTEC is IO-mapped and the SIS3100 is memory mapped, there was
no problem in running them in parallel. Note however that there will soon be an
improved version of the SIS3100 with improved speed, and also CAEN plans a WFD
with 32 channels, 6 GSPS, 12 bit, using the DRS chip for the next year. I don't
know if you need that, but just that you know.
Best regards,
Stefan |

Not much. Try to clean up the ODB (delete the .ODB.SHM file, remove all shared
memory via ipcrm) and run again. I run under kernel 2.6.18 and glibc 2.5 and this
problem does not occur. If you cannot fix it, try to run mlogger inside gdb and
make a stack trace to see who called the free(). |

Sorry for being vague. I cleaned up the ODB, but it doesn't seem to be the
problem. Here is a sample run of mlogger and gdb:

Thanks for the info, that explained the problem. It is related to the lines
rargv[rargc] = (char *)malloc(3);
rargv[rargc++] = "-b";
where one first allocates some memory (3 bytes), but then overwrites the pointer with
another pointer to some static memory ("-b"). The following
free(rargv[1]);
then tries to free the static memory which fails.
The problem was already fixed some time ago, so please update your version from the SVN
revision (see https://midas.psi.ch/download.html for details). |

I wanted to check out the latest websvn midas repository viewer installed at PSI, so I used the web "annotate/blame" tools
to trace the fix to this bug down to revision 3660 committed in April 2007. (It turns out that "svn blame" is not very useful
for tracing *removed* lines, so I ended up doing a manual binary search across different revisions of mlogger.c)

Derek Escontrias | Forum | Question - ODB access from a custom page | Hi, I am looking for a way to mutate ODB values from a custom page. I have been
using the edit attribute for the 'odb' tag, but for some things it would be nice
if a form can handle the change. I have seen references to ODBSet on the forums,
but I haven't been able to find documentation on it. Is there an available
Javascript library for Midas and/or are there more tags than I am aware of (I am
only aware of the 'odb' tag)? |

Suzannah Daviel | Forum | Question - ODB access from a custom page | At present the only documentation on the Javascript library is in this elog
e.g. Message 496 31 Jul 08
The Javascript library which you can view
http://<your mhttpd host>/mhttpd.js
now supports ODBEdit as well as ODBGet and ODBSet
I advise you get the latest version of mhttpd.c so you can use ODBEdit which changes
the ODB value directly via ODBSet.
You use it like this:
document.write('<a href="#" onclick="ODBEdit(/Equipment/test/Variables/Demand[0])">');
document.write('<odb src="/Equipment/test/Variables/Demand[0]">');
document.write('</a>');
You can also use HTML to edit the variables, but the advantage of Javascript is that
you can use variable ODB paths, so it is more powerful.
Here is an example of using a form on a custom page to edit a variable (in the
example, the run number) using Javascript (ODBEdit) and HTML.
To try this example, in ODB, create key (STRING)
/custom/try&
and set it to "/home/user/try.html"
where the path of the example code on the disk is /home/user/try.html
This will put an alias link on the Main Status page called "try" which you click on
to see the custom page.
Code of try.html:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 TRANSITIONAL//EN">
<html><head>
<title> ODBEdit test</title>
<script src="/js/mhttpd.js" type="text/javascript"></script>
<script type="text/javascript">
var my_action = '"/CS/try&"'
var rn
var path
document.write('</head><body>')
document.write('<form method="get" name="form2" action='+my_action+'> ')
document.write('<input name="exp" value="'+my_expt+'" type="hidden">');
document.write('Using Javascript and ODBEdit:
')
path='/runinfo/run number'
rn = ODBGet(path)
document.write('Run Number: '+rn+'
')
document.write('Edit Run Number:')
document.write('<a href="#" onclick="ODBEdit(path)" >')
document.write(rn)
document.write('</a>');
document.write('
') ;
</script>
Using HTML :
Using edit=2 ... Run Number:
<odb src="/runinfo/run number" edit=2>
Using edit=1 ... Run Number:
<odb src="/runinfo/run number" edit=1>
</form>
</html>
Note the "edit=2" feature is handy so that you can use Javascript or HTML on your
page and the user sees no difference.

Dawei Liu | Forum | Analyzer gets killed cm_watchdog |
Hello Midas experts:
We have setup a DAQ using MIDAS to readout two ADCs in the crate.
We are running into problem of analyzer getting killed between
runs. Sometimes it would crash after a few runs and sometimes it
would go on for many many runs before analyzer gets killed. It always
occurred between runs not when we are taking data. Any suggestions
on what we could try? The error message from the midas.log file is
appended below.
Thanks,
Dawei

Stefan Ritt | Forum | Analyzer gets killed cm_watchdog | Hi,
your log script sound to me like the analyzer either got into an infinite loop or
did a segment violation and just died. I would recommend to run the analyzer from
inside the debugger. When you then get the segment violation, you can inspect the
stack trace and see where the bad things happen. Since the analyzer works nicely in
other experiment, I expect that your problem is related to the user code. Maybe it
happens at the end of the run, but there is a timeout before the crashed process
gets cleaned from the ODB, that's why you might think that it happens "between"
runs.
Best regards,
Stefan

Jimmy Ngai | Forum | MIDAS mhttpd custom page questions | Dear All,
I have created a custom page (please see the attachment) and imported into
MIDAS with key name "Control panel&" (without the ""). I have the following
two questions:
1) I display the status of the run with <odb src="/Runinfo/State">, but it
returns numbers which is not user friendly. How can I make something
like "Running" with green background and "Stopped" with red background in the
default status page?
2) When I click either Start/Stop/Pause/Resume, it can performs the right
things, but afterward it jumps to the page "http://domain.name:8081/CS/" which
shows "Invalid custom page: NULL path". How can I make it returns to the
correct page "http://domain.name:8081/CS/Control%20panel"?
Thank you for your attention.
Best Regards,
Jimmy |
