Error gensym run not successful

Dear Ren-Jie,
Can you please try doing the following:

cd to the directory you exported

./bin/cleanall
./bin/generate_events

If this works, it may be that some of the .o files have not been updated it you have run first with internal pdfs and then with LHAPDF ones

If this does not work, can you please cd to any of the P0_xxxx directories inside SubProcesses and execute gensym by hand

./gensym < input_app.txt

and send me what you get?

Thanks a lot,

Marco

Hi Marco,

Thanks for your help.

I tried the following tests, it is still not working, get the same error message.

./bin/cleanall
./bin/generate_events

While, when I try to do your second suggestion, I cannot find any input_app.txt in SubProcesses/P0_xxxx directories.

Do you have more suggestions I can try?

p.s. It seems the latest MG5_aMC_v2_1_2_beta version has the same problem.

Thanks a lot;
Ren-Jie

Hi Renje,
i see.
can you please do the following:

open bin/intermal/madevent_interface.py
 and insert after line 2519 ( (stdout, stderr) = p.communicate(sym_input)
)
 these two lines

print ‘OUTPUT’, output
print ‘ERROR’, error

with the same indentation as the line above.

then send me what you get printed on the screen.

Thanks a lot,

Marco

Hi Macro,

I assume you let me print out stdout and stderr instead of output and error,
because in function do_survey(self, line): there is no output and errors defined.

stdout:
OUTPUT: Full compression. Using symmetry and assuming B.W.
 Warning: parameter nhel_survey not found
          setting it to default value 0

Thanks;
Ren-Jie

Hi Renje,
yes, indeed, i meant that…
Thanks for sending the output, we’ll try to investigate what is going on

Olivier, do you have any clue?

Cheers,

Marco

Hi Marco,

Do you have any ideas about this problem, I found something as follows:
1.
in SubProcesses/P0_qq_zxxx_z_ll/
symfact.dat is missing

2. it looks like gensym is not complied correctly, after I add symfact.dat manually, it just print out
------------------------------------------------------------
 Full compression. Using symmetry and assuming B.W.
 Warning: parameter nhel_survey not found
          setting it to default value 0
Segmentation fault
------------------------------------------------------------
it cannot read all parameters.

Let me know if you have something to suggest, I wish to debug this soon.

Thanks;
Ren-Jie

Hi,

I tried MG5_aMC_v2_1_2, the issue still there.
Also, I want to mention, the issue appears in SLC5, I tried Mac OS X, it works fine.

Cheers;
Ren-Jie

Hi Ren-Jie,
can you please check this page
http://amcatnlo.web.cern.ch/amcatnlo/list_detailed2.htm#dependencies
in particular what concerns the configuration/dependencies on SL5?
Cheers,

Marco

Hi Marco,

I did some changes with the gcc/gfortran4.7 on SLC5, it looks getting started to work, at least it takes LHAPDF to download the correct PDFSets, while a new error message appears:

Program received signal SIGSEGV: Segmentation fault - invalid memory reference.

Backtrace for this error:
#0 0x2B0B98DE3F47
#1 0x2B0B98DE4514
#2 0x2B0B998052CF
#3 0x463F50 in setpara_
#4 0x4060C6 in MAIN__ at symmetry.f:0

Any more suggestions?

Thanks;
Ren-Jie
