condor_power(1) General Commands Manual condor_power(1) Name condor_power send - packet intended to wake a machine from a low power state Synopsis condor_power [-h] condor_power[-d] [-m MACaddress] [-s subnet] [ClassAdFile] Description condor_powersends one UDP Wake on LAN (WOL) packet to a machine specified either by command line arguments or by the contents of a machine ClassAd. The machine ClassAd may be in a file, where the file name specified by the optional argument ClassAdFileis given on the command line. With no command line arguments to specify the machine, and no file specified, condor_powerquietly presumes that standard input is the file source which will specify the machine ClassAd that includes the public IP address and subnet of the machine. condor_powerneeds a complete specification of the machine to be successful. If a MAC address is provided on the command line, but no subnet is given, then the default value for the subnet is used. If a subnet is provided on the command line, but no MAC address is given, then condor_powerfalls back to taking its information in the form of the machine ClassAd as provided in a file or on standard input. Note that this case implies that the command line specification of the subnet is ignored. Options -h Print usage information and exit. -d Enable debugging messages. -m MACaddress Specify the MAC address in the standard format of six groups of two hexadecimal digits separated by colons. -s subnet Specify the subnet in the standard form of an IP address. Without this option, the default subnet used will be 255.255.255.255, causing a broadcast. Exit Status condor_powerwill exit with a status value of 0 (zero) upon success, and it will exit with the value 1 (one) upon failure.

condor_findhost(1) General Commands Manual condor_findhost(1) Name condor_findhost find - machine(s) in the pool that can be used with minimal impact on currently running Condor jobs and best meet any spec- ified constraints Synopsis condor_findhost [-help] [-m] [-n num] [-c c_expr] [-r r_expr] [-p centralmanagerhostname] Description condor_findhostsearches a Condor pool of machines for the best machine or machines that will have the minimum impact on running Condor jobs if the machine or machines are taken out of the pool. The search may be limited to the machine or machines that match a set of constraints and rank expression. condor_findhostreturns a fully-qualified domain name for each machine. The search is limited (constrained) to a specific set of machines using the -coption. The search can use the -roption for rank, the criterion used for selecting a machine or machines from the constrained list. Options -help Display usage information and exit -m Only search for entire machines. Slots within an entire machine are not considered. -n num Find and list up to nummachines that fulfill the specification. numis an integer greater than zero. -c c_expr Constrain the search to only consider machines that result from the evaluation of c_expr. c_expris a ClassAd expression. -r r_expr r_expris the rank expression evaluated to use as a basis for machine selection. r_expris a ClassAd expression. -p centralmanagerhostname Specify the pool to be searched by giving the central manager's host name. Without this option, the current pool is searched. General Remarks condor_findhostis used to locate a machine within a pool that can be taken out of the pool with the least disturbance of the pool. An administrator should set preemption requirements for the Condor pool. The expression (Interactive =?= TRUE ) will let condor_findhostknow that it can claim a machine even if Condor would not normally preempt a job running on that machine. Exit Status The exit status of condor_findhostis zero on success. If not able to identify as many machines as requested, it returns one more than the number of machines identified. For example, if 8 machines are requested, and condor_findhostonly locates 6, the exit status will be 7. If not able to locate any machines, or an error is encountered, condor_findhostwill return the value 1. Examples To find and list four machines, preferring those with the highest mips (on Drystone benchmark) rating: condor_findhost -n 4 -r "mips" To find and list 24 machines, considering only those where the kflops attribute is not defined: condor_findhost -n 24 -c "kflops=?=undefined" Author Condor Team, University of Wisconsin-Madison Copyright Copyright (C) 1990-2012 Condor Team, Computer Sciences Department, University of Wisconsin-Madison, Madison, WI.
