#summary Changelog of distributed PPSS #labels Featured === 2.21 === - Fixed bug in new mechanism for detecting multiple PPSS instances. (My fault). - By default now PPSS creates a directory 'ppss' in the current working dir of PPSS. By using 'export PPSS_DIR=/some/dir' you can change the directory used. === 2.20 === - PPSS did not take into account that different users can run PPSS on a single system. This has been fixed. Thanks to Cinly Ooi - If a user is starting another instance of PPSS, the second instance will abort unless the -F option is specified. Please note that if you run multiple instances of PPSS under the same user account, all instances will process items but fail to terminate. - Improved error reporting. === 2.19 === - Improved filename sanitization. - Fixed typo. === 2.18 === - PPSS now also record CPU model of Mac OS X devices. {{{ mrt 29 23:11:56: INFO ========================================================= mrt 29 23:11:56: INFO |P|P|S|S| mrt 29 23:11:56: INFO Distributed Parallel Processing Shell Script version 2.18 mrt 29 23:11:56: INFO ========================================================= mrt 29 23:11:56: INFO Hostname: MacBoek.local mrt 29 23:11:56: INFO --------------------------------------------------------- mrt 29 23:11:56: INFO Found 2 logic processors. mrt 29 23:11:56: INFO CPU: Intel Core 2 Duo 2.16 GHz mrt 29 23:11:56: INFO Starting 2 workers. mrt 29 23:11:56: INFO --------------------------------------------------------- }}} {{{ Mar 29 23:19:12: INFO ========================================================= Mar 29 23:19:12: INFO |P|P|S|S| Mar 29 23:19:12: INFO Distributed Parallel Processing Shell Script version 2.18 Mar 29 23:19:12: INFO ========================================================= Mar 29 23:19:12: INFO Hostname: MINI.local Mar 29 23:19:12: INFO --------------------------------------------------------- Mar 29 23:19:13: INFO Found 2 logic processors.

The fact that a known_hosts file must exist when distributing PPSS to nodes was not documented. === 2.06 === * Forgot to update the version number within the script. === 2.05 === * Deployment of PPSS to nodes is now performed in parallel, by executing the deploy function with &." * It is now possible to specify the output directory and/or output filename within the -c option. === 2.04 and older === I didn't realise that a changelog might be relevant until 2.05.
