New functionality delivered with SGE 6.1 Beta:

• 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 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).
• 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 Apple Mac OS X on the x86 platform
• support for Linux on Itanium (IA64)
• delivers native 64-bit binaries for HP-UX 11
  
• a Solaris 10 DTrace script supports monitoring and helps to do a bottleneck analysis
• with the help of our community members job online usage is now supported for Apple Mac OS X, IBM AIX and HP HP-UX
• various qmon usability improvements
  
• support for FreeBSD at source code level
• for developers an early access to a Java API (JGDI) is part of the courtesy binary distribution
