{Disarmed} Re: FLUKA crash

Hi Chris,
I have solved the problem of the crash (or ... I wish so) running the
batch job on a machine with Linux - Scientific Linux 3.0.5 (32 bit) and
2 Intel(R) Xeon(TM) CPU - 2.40GHz! I point out that the executable was
compiled on a machine with Linux - Scientific Linux 3.0.5 (32 bit) and 2
AMD Opteron(tm) Processor 244 - 1.8GHz. It seams that the problem is
exclusively due to the machine employed for running the batch job: on
the machine with Linux - Scientific Linux 3.0.5 (32 bit) and 2 Intel(R)
Xeon(TM) CPU - 2.40GHz the run ended with success (I hope it was not a
... random event!).
Cheers,
noemi

Hi Chris,<br>
I have solved the problem of the crash (or ... I wish so) running the
batch job on a machine with Linux - Scientific Linux 3.0.5 (32 bit) and
2 Intel(R) Xeon(TM) CPU - 2.40GHz! I point out that the executable was
compiled on a machine with Linux - Scientific Linux 3.0.5 (32 bit) and
2 AMD Opteron(tm) Processor 244 - 1.8GHz. It seams that the problem is
exclusively due to the machine employed for running the batch job: on
the machine with Linux - Scientific Linux 3.0.5 (32 bit) and 2 Intel(R)
Xeon(TM) CPU - 2.40GHz the run&nbsp; ended with success (I hope it was not a
... random event!).<br>
Cheers,<br>
noemi<br>

  <pre wrap="">Hi Noemi,
the symptoms you describe are identical to a case I was dealing with
just a couple of weeks ago. It seems that these mysterious FLUKA crashes
occur on AMD chips with K8/K10 core architectures running under a 32 bit
linux. This is independent of the distribution as I tried several
different ones, with different math libs etc. Currently, the reason is
not yet fully clear so I would suggest to follow the steps that Paola
described in her mail from yesterday as it would be helpful to pinpoint
the problem to a specific scenario.
In the meantime I can only offer a remedy which solved this problem in
our case. If you have the possibility you should try to switch to a 64
bit version of linux. I ran your input on such a machine we previously
had problems with and which is now running the 64 bit version of linux.
Your input finished gracefully following exactly the same random number
sequence like on your machine, just as expected.
All 32 bit programs will be running under the 64 bit OS as well but you
might need to install a couple of additional libraries for FLUKA to
work. Some hints can be found in the following presentation of a
colleague which could be helpful:
<a class="moz-txt-link-freetext" href="http://info-fluka-discussion.web.cern.ch/info-fluka-discussion/talks/Ludovic_From32To64_190407.ppt">http://info-fluka-discussion.web.cern.ch/info-fluka-discussion/talks/Ludovic_From32To64_190407.ppt</a>
I saw that you're sending your jobs to a LSF batch system and probably
cannot change the OS there. In that case you might try to investigate
the possibilities to exclude certain architectures (I'd suggest AMD
Opteron and Phenom CPUs) from the scheduling process.
Cheers
Chris

Hi Christian,
1) I am using a 32 bit version of SLC3;
2) when I run my FLUKA job the crash on the batch machines occurs at
differnt points  (sometimes it occurs earlier and sometimes later).

Hi Noemi,

I'm currently looking into your problem and I would need some more
information. Could you please answer the following questions which would
help me to check whether this problem is similar to one that I have seen
just recently:
=20
- Are you using the 32 bit or the 64 bit version of SLC3?
=20
- When you run your FLUKA job does the crash on the batch machines
always occur at the same
  point or does it sometimes occur earlier and sometimes later?
=20
- Could you please run the following command on the execution PC and
send me the output
  "cat /proc/cpuinfo"

Ciao

color:#1F497D'&gt;the symptoms you describe are identical to a case I was =
dealing
with just a couple of weeks ago. It seems that these mysterious FLUKA =
crashes
occur on AMD chips with K8/K10 core architectures running under a 32 bit =
linux.
This is independent of the distribution as I tried several different =
ones, with
different math libs etc. Currently, the reason is not yet fully clear so =
I
would suggest to follow the steps that Paola described in her mail from
yesterday as it would be helpful to pinpoint the problem to a specific
scenario.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class=3DMsoNormal&gt;&lt;span =
style=3D'font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'&gt;&lt;o:p&gt;&amp;nbsp;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class=3DMsoNormal&gt;&lt;span =
style=3D'font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'&gt;In the meantime I can only offer a remedy which solved =
this
problem in our case. If you have the possibility you should try to =
switch to a
64 bit version of linux. I ran your input on such a machine we =
previously had
problems with and which is now running the 64 bit version of linux. Your =
input finished
gracefully following exactly the same random number sequence like on =
your
machine, just as expected.&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class=3DMsoNormal&gt;&lt;span =
style=3D'font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'&gt;&lt;o:p&gt;&amp;nbsp;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
&lt;p class=3DMsoNormal&gt;&lt;span =
style=3D'font-size:11.0pt;font-family:"Calibri","sans-serif";
color:#1F497D'&gt;All 32 bit programs will be running under the 64 bit OS =
as well
but you might need to install a couple of additional libraries for FLUKA =
to
work. Some hints can be found in the following presentation of a =
colleague which
could be helpful:&lt;o:p&gt;&lt;/o:p&gt;&lt;/span&gt;&lt;/p&gt;
