New functionality delivered with this SGE 6.1preview2 release:

• the complex string attributes (CSTRING, STRING, RESTRING, HOST) has been enhanced to allow regular boolean expressions for wildcards or patterns. The new syntax is defined in the sge_types(1) man page and examples can be found in complex(5).
• enhanced Resource Quota dynamic limit syntax to allow constant summands. The new syntax for a dynamic limit is
  

  {w1|$complex1[*w1]}[{+|-}{w2|$complex2[*w2]}[{+|-}...]]
  

• changed Resource Quota expanded list format from backquotes '`expanded_list`' to the more "shell-like" use of '{expanded_list}'
• the environment variable LD_LIBRARY_PATH is no longer set for Solaris and Linux by the Grid Engine settings.[c]sh file. Instead the dynamic library path is determined at runtime.
• new switch "-wd" for qsub, qalter, qsh, qrsh and qmon to specify the job working directory.
• MySQL support for the Grid Engine Accounting and Reporting Console (ARCo)
• support for FreeBSD at source code level
• various qmon usability improvements provided by Hin-Tak Leung

New functionality delivered with the SGE 6.1preview1 release:

• Resource Quotas allow to limit the maximum number of running jobs per user, user group, projects on arbitrary resources like queues, hosts, memory, software licenses. A firewall-like rule syntax allows an unprecedented flexibility in defining Grid Engine Resource Quotas (RQ). The man pages qquota(1), sge_resource_quota(5) and qconf(1) describe the new functionality. The design of the Resource Quotas can be found here
