Aleph Software

Aleph software under Linux

• The lists of programs/libraries that works under Linux:
  Alephlib, Alpha (with/without PVM), Bos77, Dali, Galeph, Julia, Look, Mini, Scanbook, TPCsim, dbase tools (sbank, hacpar, etc ...). (Updated April 1999).
• On AFS under the standard Aleph directories there is directory called i386_redhat42. Under this directory you will find most Aleph software compiled for the i386 architechture under RedHat 4.2. These directories contains a copy of the architechture dependent directories from lscf. For RedHat 5.x one should use the directory i386_redhat51. These names follows the CERN system naming convention for AFS. Note: At this time the i386_redhat51 directories contains mainly links to i386_redhat42. That should not be a problem for normal use though.
• For all of the above programs and libraries there exists RPM's build under RedHat 4.2. Contact me for information on how to access them via ftp.
• What is not tested/does not work?
  • alwho is not included since it uses Fortran 90 and not Fortran 77.
  • Kingal is untested and therefore not currently available. I have no time to personally test all the generators on Linux. However I do have RPM's for all of them. If you would like and RPM of your favourite generator mady publically available, I can give you a copy and you can test it against versions on other platforms. The basic Kingal routines works. Currently Jetset and Excalibur has been succesfully tested.
• The ALEPH libraries were compiled using these optimizations:

             -O2 -ffloat-store -fomit-frame-pointer -fno-strength-reduce
             -m486 -malign-loops=2 -malign-jumps=2 -malign-functions=2
        

• At login the startup scripts should have these declarations (for tcsh):

        setenv VENDOR Linux
        setenv CPPOPT "-DUNIX -DALEPH_LINUX -I${ALINC}"
        setenv FCOPT  "-c -O -fno-automatic -fdollar-ok -fno-backslash $CPPOPT"
        setenv FC    g77
        setenv CCOPT " -c -O -DALEPH_C -I${ALINC}"
        

  You might want to add -ffloat-store to FCOPT as well. This helps programs that relies on IEEE conformance by lowering the precision at some cost in speed. The option is effective when the FPU is set to extended precision (default). It also ensures that the output is the same whith and without optimization.

Color Reconnection

• dumpcrc.F
  Routine to save the LUND common in a bank. The routine will also make rearrangement to the common to prepare it for the Color Reconnection program crckin.F.
• crckin.F
  The program that does the actual Color Reconnection. This assumes that Kingal events were created with dumpcrc.F included.
• crckin.cards
  Sample cards file for crckin.cards
• crckin.mk
  Makefile for crckin.mk
• bcs.h inout.h ludat1.h ludat2.h ludat3.h ludatr.h lujets.h sjkhcr.h
  Special include files for crckin and dumpcrc
• crckin.tar.gz
  Complete package with all of the files mentioned above. The files is compressed using tar and gzip.
