Changed behavior
Open advance
reservations
Open advance reservations allow jobs to run even after the associated reservation
expires. A job with the open advance reservation will only be treated as an advance
reservation job during the reservation window, after which it becomes a normal job. This
prevents the job from being killed and ensures that LSF does not prevent any previously
suspended jobs from running or interfere with any existing scheduling policies.
Enforcement of dual-core CPU licenses on Linux
Dual-core CPU hosts running Linux must be licensed by the lsf_dualcore_x86
license feature.
Each dual core processor requires one standard LSF license and one
lsf_dualcore_x86 license. Use lshosts -l to see the number of dual-core
licenses enabled and needed.
Enforcement of grid license managment plugin licenses
The new license optimization features enabled by the grid license management plugin
require the
lsf_mv_grid_filter license feature.
The number of
lsf_mv_grid_filter licenses should be at least the number of LSF
License Scheduler licenses.
Banded licensing
You can use permanent licenses with restictions in operating system and hardware
configurations. These banded licenses have three classes, with the E-class licenses
having no restrictions. Banded licenses support the following operating systems and
hardware configurations:
License type Supported operating systems Supported hardware
B-Class Linux and Windows X86/AMD64/EM64T
Up to two CPUs and 4 GB physical
memory on a node
S-Class Linux and Windows X86/AMD64/EM64T
Up to four CPUs and 8 GB physical
memory on a node
Itanium2
Up to two CPUs and 4 GB physical
memory on a node
E-Class All LSF-supported operating systems All hardware
