When the master LIM starts, up to number_of_floating_client_licenses will be checked
out for use as floating client licenses. If fewer licenses are available than specified by
number_of_floating_client_licenses, only the available licenses will be checked out and
used.
If FLOAT_CLIENTS is not specified in
lsf.cluster.cluster_name or there is
an error in either
license.dat or in lsf.cluster.cluster_name, the floating
LSF client license feature is disabled.
WARNING
When the LSF floating client feature is enabled, any host will be able to
submit jobs to the cluster. You can limit which hosts can be LSF floating
clients with the parameter FLOAT_CLIENTS_ADDR_RANGE in
lsf.cluster.cluster_name.
LSF Floating Client
Although LSF Floating Client requires a license, LSF_Float_Client does not need to be
added to the PRODUCTS line. LSF_Float_Client also cannot be added as a resource for
specific hosts already defined in lsf.cluster.cluster_name. Should these lines be
present, they are ignored by LSF.
Default
Undefined
FLOAT_CLIENTS_ADDR_RANGE
Syntax
FLOAT_CLIENTS_ADDR_RANGE=
IP_address ...
Description
Optional. IP address or range of addresses, in dotted quad notation
(
nnn.nnn.nnn.nnn), of domains from which floating client hosts can submit
requests. Multiple ranges can be defined, separated by spaces.
If the value of this parameter is undefined, there is no security and any hosts can be LSF
floating clients.
If a value is defined, security is enabled. If there is an error in the configuration of this
variable, by default, no hosts will be allowed to be LSF floating clients.
When this parameter is defined, client hosts that do not belong to the domain will be
denied access.
If a requesting host belongs to an IP address that falls in the specified range, the host
will be accepted to become a floating client.
IP addresses are separated by spaces, and considered "OR" alternatives.
The asterisk (*) character indicates any value is allowed.
The dash (-) character indicates an explicit range of values. For example 1-4 indicates
1,2,3,4 are allowed.
Open ranges such as *-30, or 10-*, are allowed.
If a range is specified with less fields than an IP address such as 10.161, it is considered
as 10.161.*.*.
Address ranges are validated at configuration time so they must conform to the required
format. If any address range is not in the correct format, no hosts will be accepted as
LSF floating clients and an error message will be logged in the LIM log.
This parameter is limited to 255 characters.
