Hi,

Thanks Maarten for replying. I've included all the output files and directories in the "working directory" : flukawork when I run over the
example.inp by doing :
$FLUPRO/flutil/rfluka -N0 -M5 example &

in the tar-gzipped file "example.tar.gz". You can find output files up to cycle 3 and since it's stuck (at event ~56000 at cycle 4) the output file for
cycle 4 are in the directory "fluka_29895".

I also show you the "output screen" if this is of any use :

It'll be stuck there forever (well, I've tried to wait overnight).

Dear Kin, dear Nacira,

Could you send some more information? The way to troubleshoot Fluka is through the files it gives you back. For every run it has done, there should be a .log, .err, .out and a random seed. If you could attach these to an email (together with your input file) then people can help troubleshoot. If there are no files generated at all, then it is very likely your fluka installation procedure went wrong somewhere.

For Nacira, I think that Fluka is not compiled correctly - the output files mentioned above will give more information. For Kin, I do not know why your file is stopping at a random point, but hopefully the files can give some more information!

Regards,

Maarten

Subject: Re: [fluka-discuss]:

Hi Nacira,

Are you using 32-bit executable of Fluka ?

I'm a new Fluka user. I can only build/compile the 32-bit Fluka as I don't have gfortran7.4 nor 8.3.

I have built 32-bit Fluka executables (flukahp) in two machines of 64-bit, one is running Scientific Linux (=Red-Hat) 6 and the other one is Scientific Linux 7.

But in both machines (which are built a bit differently), when I ran on "example.inp", it would stop or get stuck somewhere at cycle 4, after (eg. in one machine)
56000 events. I wonder why this happened ?! It'd finish 3 cycles nicely.

I've tried to put in TIME-CUT what(4) and what(5) (in case there is an infinite loop) but it doesn't help. Setting What(6) doesn't help either.

If I change the RANDOMIZ in example.inp, it'd change where it'd stop (eg. it may stop earlier !) but it can never get past cycle 4.

I've also tried to change -O3 to -O0 or get rid of "-mcpu=... -fexpensive-optimizations" in the compilation. But all these don't help either (it'd still get stuck at
cycle 4 when I run the original example.inp).

I hope the experts can tell us what's wrong :-(

Dear Fluka Experts,

I tried the same thing with simple examples I worked on before but the results were the same.
