Hello everyone,
sorry to bother you but I've got some issues when I try to produce NTUPLES
with MCFM, a Monte Carlo generation software.
Whenever I try to produce an NTUPLE as output, either a segmentation error
occurs or the following message pops up:
RZOPEN. record length: 8192 > maximum safe value (8191 words).
Oh, ZEBRA. Not used very often nowadays.
RZOPEN. You may have problems transferring your file to other systems
or writing it to tape.
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
locf_() Warning: changing base from 0 to 7fff00000000!!!
This may result in program crash or incorrect results
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
and the produced NTUPLES are either corrupted or empty (every entry is set
to 0).
This is how I setup the software:
I untar the last version of LHAPDF 6, then I configure the installation:
./configure --prefix=[INSTALLATION PATH] --with-boost=[BOOST PATH]
--disable-python
then I execute make && make install
Since I need CERNLIB to produce the NTUPLES and I was not able to find a
specific version for SLC6,
There is one in the SLC6 repository, should not be that difficult to find:
pc.cern.ch[103] rpm -q CERNLIB
CERNLIB-2006a-5.slc6.i686
pc.cern.ch[104]
This is i686 "only", but that might even be safer than the x86_64, not
sure how well zebra can digest 64 bitness.
I've downloaded the following one:
PC Linux Cern x86_64-slc5-gcc43-opt(Cernlib 2006)
Not far from that one there should also be a slc6 version, if you insist
on x86_64.
Best regards,
Matthias
Finally, I've untared MCFM-7.0 source code, put the path to CERNLIB and
LHAPDF libraries in the Install file, setting USE_OMP to NO, NTUPLES to YES
and PDFSET to LHAPDF in the makefile and executed:
./Install
make
I've created a symbolic link in Bin directory to LHAPDF's PDFsets and
executed the program selecting process 146 in the Input.DAT file and
setting .creatent. to true (in order to produce NTUPLES with:
./mcfm [relative path to the folder containing the input file] input.DAT
Sorry again for bothering you with this.
Cheers,
Matteo
