SixTrack / BOINC Updates Veronica Berglyd Olsen General SixTrack Meeting Thursday, 13 June 2019
Already Implemented Updates Issues with Previous Versions Fixes Made ◾ Previous BOINC releases of ◾ A BOINC linked SixTrack will now SixTrack were tuned for DA studies ignore the numlcp setting and with few particles and many turns. instead request to the API to checkpoint every 61 seconds. ◾ Checkpointing was done by default ◾ The BOINC manager by default on every 1000 turn. allows checkpointing every 60 ◾ The user does not necessarily know seconds. they need to tune this value or set ◾ If run without the BOINC manager it. (standalone mode), SixTrack ◾ The volunteer may have few-turn checkpoints every 10 seconds. It jobs start from scratch on a restart. also obeys the CRKILLSWITCH . 13.06.2019 SixT rack Genral Meeting 2
Further Issues to Address Need for a New Job Validation System (Alessio) ◾ Many-particle, few-turn jobs still have the issue of how to validate the results. ◾ Currently, this is done by checking the fort.10 file. However, this file grows very large for many-particle jobs. It is also not necessarily the only file that should be validated. Solution Proposed (Code Written, but not Merged) ◾ We constructed a new file format that contains necessary job information and a list of MD5 file sums for the files we want to validate. ◾ The timing information is removed from fort.10 so the file can be hashed, and the timing is instead written in the new results file. 13.06.2019 SixT rack Genral Meeting 3
