LSF Version 7.3 - Administering Platform LSF

Administering Platform LSF 195
Managing LSF on Platform EGO
LSF and EGO require exclusive use of certain ports for communication. EGO uses
the same four consecutive ports on every host in the cluster. The first of these is
called the base port.
The default EGO base connection port is 7869. By default, EGO uses four
consecutive ports starting from the base port. By default, EGO uses ports
7869-7872.
The ports can be customized by customizing the base port. For example, if the base
port is 6880, EGO uses ports 6880-6883.
LSF and EGO needs the same ports on every host, so you must specify the same
base port on every host.
Special resource groups for LSF master hosts
By default, Platform LSF installation defines a special resource group named
ManagementHosts for the Platform LSF master host. (In general, Platform LSF
master hosts are dedicated hosts; the ManagementHosts EGO resource group
serves this purpose.)
Platform LSF master hosts must not be subject to any lend, borrow, or reclaim
policies. They must be exclusively owned by the Platform LSF consumer.
The default Platform EGO configuration is such that the LSF_MASTER_LIST
hosts and the execution hosts are in different resource groups so that different
resource plans can be applied to each group.
