Default

LSF_ELIM_BLOCKTIME

Syntax

LSF_ELIM_BLOCKTIME=

seconds

Description

UNIX only

Maximum amount of time LIM waits for a load update string from the ELIM or

MELIM if it is not immediately available.

Use this parameter to add fault-tolerance to LIM when using ELIMs. If there is an error

in the ELIM or some situation arises that the ELIM cannot send the entire load update

string to the LIM, LIM will not wait indefinitely for load information from ELIM. After

the time period specified by LSF_ELIM_BLOCKTIME, the LIM writes the last string

sent by ELIM in its log file (

lim.log.host_name) and restarts the ELIM.

For example, if LIM is expecting 3 name-value-pairs, such as:

3 tmp2 49.5 nio 367.0 licenses 3

If after the time period specified by LSF_ELIM_BLOCKTIME LIM has only received

the following:

3 tmp2 47.5

LIM writes whatever was received last (

3 tmp2 47.5) in the log file and restarts the

ELIM.

Valid Values

Non-negative integers

A value of 0 indicates that LIM will not wait at all to receive information from ELIM—

it expects to receive the entire load string at once.

So, if for example, your ELIM writes value-pairs with 1 second intervals between them,

and you collect 12 load indices, you need to allow at least 12 seconds for the ELIM to

complete writing an entire load string. So you would define LSF_ELIM_BLOCKTIME

to 15 or 20 seconds for example.

Default

2 seconds
