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). 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, I've downloaded the following one: PC Linux Cern x86_64-slc5-gcc43-opt(Cernlib 2006) 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
