Timeout

Global Setting.

The run-time execution time limit for all problems can be specified with the timeout key. A time limit can be overridden if a timeout is specified in the problem.yaml file.

# set run time limit for all problems to 20 seconds
timeout: 20

Load Data Files

In 9.3 files are loaded internally (stored within pc2) by default. A feature where one can use a CDP location

Load data files internally or externally.

load-data-files: true
load-data-files: false

Example of load-data-files in contest.yaml

# Contest Configuration, version 1.0
#
# PC^2 Version: Version 9.3 20151021 (Wednesday, October 21st 2015 03:55 UTC) Java ver 1.7.0_51 build 3230 Windows 7 6.1 (amd64)
#
# Created: 2015-10-22 21:46:00 PDT

name: '2015 CSUS Fall Contest'
short-name: '2015 Fall Contest'
start-time: 2015-10-23 17:00
duration: 4:00:00
# freeze time before end of contest
scoreboard-freeze: 1:00:00

# use external CDP files
load-data-files: false

# Judge CDP config path
judge-config-path: /home/team/cdp/config

(One other way to specify external files is in the admin pc2v9.ini file, set [server] externalfiles=yes, but using load-data-files is preferable.

Judge CDP Path

For files that are external to pc2 a Judge's path may be needed.

Under some circumstances the external CDP files will be under a different directory on the judge than the admin. To specify a different directory use:

judge-config-path: /home/pc2/cdp/config

Via the Admin UI specify the value in the field Location for Judge CDP Config on the Problems tab.
