Full Discussion: Perl script limit cpu usage
Operating Systems HP-UX Perl script limit cpu usage Post 302730491 by sai_2507 on Tuesday 13th of November 2012 04:30:48 AM

Perl script limit cpu usage
Hi Experts,

I am executing multiple instances(in parallel) of perl script on HP-UX box.

OS is allocating substantial amount of CPU to these perl processes,resulting higher cpu utilization.

Glance always shows perl processes are occupying majority of the CPU resource. It is causing slower response time for other processes as majority of the cpu resource is always occupied by perl processes.

Is there any way to limit the amount of cpu used by perl processes?

Thanks in Advance for your help!!

NAME

       cpu - A tool for user and group administration

SYNOPSIS

       cpu [OPTIONS]

DESCRIPTION

       CPU is a tool for user administration, that was initially based on FreeBSD's pw(8). This tool will allow you to administer users and groups
       on several different backends currently including LDAP and flat files. Please see the website http://cpu.sourceforge.net for more  informa-
       tion, or help improve the man page.

OPTIONS

       There are two kinds of options; options for CPU and options for CPU modules.  There are only four options for CPU, they are as follows:

       -C configfile, --config configfile
              The configuration file to be used by CPU. The options in this file are used for CPU modules.

       -h, --help
              Display help for CPU. If specified in conjunction with the -m option the help for that particular module is displayed.

       -M method, --method=method
              This  is  the method of administration. Current options are ldap or passwd (passwd is not yet working). This can be specified in the
              configuration file.

       -V, --version
              Display the version of the software.
