- This is the Condor source distribution version 4.1.3b. This is a beta
- test, but should be fairly stable as it is based largely on the results
- of the 4.1b beta testing.
-
- Highlights of the changes from version 4.1.0b
-
- Suns: Due to the different format used by SunOS for core files, the
- checkpointing code previously used was *very* inefficient. In
- fact it was so inefficient that in some cases condor jobs would
- spend allmost all their time checkpointing, and make very
- little progress. This has been fixed for all programs which
- use the stack pointer in the conventional way. This includes
- most C and Fortran programs. There is still another case where
- the new code will also be very inefficient and that is the case
- where the application program manipulates the stack pointer so
- that it is actually pointing into the "data" area. This will
- generally be true for programs which use threads or coroutines.
- We expect to fix this problem in the next realease.
-
- R6000: Checkpointing is now supported for R6000's running AIX3.1.
- We have not yet tried to build Condor on an AIX3.2 machine,
- but have some experience to indicate that at least binaries
- compiled under 3.1 will work on 3.2 machines. We will be
- building Condor for 3.2 machines in the near future.
-
- NFS: Previously a bug existed in the code which condor uses to
- access remotely mounted file systems. This bug only
- happened when the number of mounted systems was fairly
- large (around 40), and is now fixed.
-
-
- We have tested this code on the following platforms:
-
- Sun 4, (SPARC) machines running SunOS 4.1 and 4.1.1
- DECstation 3100 and 5000 series machines running Ultrix 4.2
- IBM R6000 series machines running AIX3.1.5
-
- We hope to begin supporting the following platforms sometime in the
- not too distant future:
-
- HP9000-700 machines running HPUX 8
- Silicon Graphics 4D workstations running IRIX 4.0
-
- We will no longer be supporting these platforms:
- IBM RT's
- Sun 3's (68000 based)
- HP Bobcats (68000 based)
-
- The following bugs are known and remain in this distribution:
- 1. On R6000s the process which detects keyboard and mouse activity
- may miss some events. This generally happens when the motif
- window manager (mwm) is running. We expect to fix this in the
- next distribution.
-
- Postscript ready documentation is included in the "doc/POSTSCRIPT"
- directory. Line printer ready versions of the "man pages" are included
- in the "doc/CAT" directory. Documents other than the man pages cannot
- be printed on a line printer because they contain postscript figures.
- If you cannot print postscript files, send me your physical mail
- address (via email if you can), and I will send you printed copies.
-
- Hints: If you are upgrading from version 4.1b, please save copies of all
- the files in your "config" directory as well as any changes to
- "condor_config" or "condor_config.local". There are some changes
- to the new config files, so you cannot just copy in your old ones, but
- knowing what customization you did last time should make it very
- easy to customize the new ones.
