We are pleased to announce the official release of TORQUE 2.5.0.
Improved job arrays and Cygwin support are the main new features for
_Please be advised that the job arrays in 2.5.0 are not backward
compatible with TORQUE 2.4.x or 2.3.x. Anyone upgrading to 2.5.0 that is
currently using job arrays needs to be sure to drain all job arrays from
their system before upgrading._
New features of job arrays include slot limits which allows users and
administrators to control the number of simultaneous running jobs from a
job array submission. Job dependencies can also be based on entire
arrays as well as individual jobs. Job arrays are now suported in the
commands qalter, qdel, qhold, qrls in addition to the qsub command.
With special thanks to Igor Ilyenko, Yauheni Charniauski and Vikentsi
Lapa TORQUE is now able to run under Cygwin. This new feature has been
created by the community and will be supported by the community.
Adaptive Computing will not officially support this feature at this time.
The 'procs' resource option is now fully supported. Previous versions of
TORQUE only passed this resource through to schedulers who then
interpreted the directive. The 'procs' features allows users to select a
number of processors for a job without the need to specify the nodes on
which the processors should come.
There is an improved wildcard support for queue and server parameters.
Previous versions of TORQUE could only match the '*' wildcard to the end
of a string. TORQUE will now support the '*' anywhere in a string.
TORQUE also added the ability to create ranges on names such as
user at node[1-5] to specify on a single line that node1 through node5
qualify for any queue or server parameter.
