The code currently runs on AIX unix and Windows NT/95. The unix environment is set up to handle multiple architectures, and has been run on AIX, DEC unix and Solaris. 'The code' means the nld executable and default initialization files, plus a root installation.
The LCD code is available here, while the underlying GISMO code is available from the GLAST experiment.
The SLAC central fileserver's group disk (V:\) contains an LCD\ folder holding all the LCD code. The latest version is in the lcd-working\ folder, while older archives are in named folders, like nld-june98. There is also an installation of root here. Visual C++ 5.0 is used and the workspace file will be found in the nld (sub)folder. The nld project defines the GUI version; conld the batch. Note that one must apply a service patch of level 3 or higher to Visual C++. See the instructions for setting up from scratch (ie arve and nld zip files).
You will need a couple of environment variables to run the code:
> set LCD_DIR=<directory containing executables nld_win and nld_bat>
> set PEGS4PATH=%LCD_DIR%/PEGS4
The code is kept in nld group space: /afs/slac.stanford.edu/g/nld (hereafter referred to as $NLDROOT)).The latest version of the code is called lcd-working; archives are named, usually by date. From time to time when production releases happen, it may be that the current lcd-working has been moved to a new directory pending installation of the new version.
The nld code is arranged to allow binaries for multiple architectures. A common source area is shared; the Gnu Makefile lives here. Batch (nld_bat) and X-windows (nld_win) versions of the exe are available in the bin/ directory. Post July '98, we have migrated to the egcs g++ compiler. GLAST has standardized on g++ 2.81 and is moving to the new egcs version. We have installed our own version of egcs (1.03) at SLAC in nld space.
You will need a couple of environment variables to run the code:
> setenv LCD_DIR <directory containing executables nld_win and nld_bat>
> setenv PEGS4PATH $LCD_DIR/PEGS4See the readme file that comes with the code distribution for any further requirements.
There are default initialization files for detector geometry and generator setup. Currently on NT, they live in the nld subfolder; on unix they live in the bin/ directory. We have two generators: NBeam - multi-particle; HepEvt - reads stdHEP files.
Interactively, one can manipulate choices by menu selections. In batch, the syntax is (eg SLAC unix):
> $LCD_DIR/nld_bat Detector.ini 'generator-name' Gen.ini 100 mydir/output.dat runNumber rndmSeed
where the first two ini files specify the geometry and generator properties; '100' is an example of 100 events; and the .dat file is the filespec of the output file. (Note for SLAC unix: farm output files go to /nfs/surrey02/nld. This is mounted only from batch farm machines - morgans, percheron, pintos, etc. /nfs/surrey01/work/ is available for general users as scratch space.
