SixTrack / BOINC Updates

Already Implemented Updates

Issues with Previous Versions

◾ Previous BOINC releases of

SixTrack were tuned for DA studies with few particles and many turns.

◾ Checkpointing was done by default

• n every 1000 turn.

◾ The user does not necessarily know

they need to tune this value or set it.

◾ The volunteer may have few-turn

jobs start from scratch on a restart. Fixes Made

◾ A BOINC linked SixTrack will now

ignore the numlcp setting and instead request to the API to checkpoint every 61 seconds.

◾ The BOINC manager by default

allows checkpointing every 60 seconds.

◾ If run without the BOINC manager

(standalone mode), SixTrack checkpoints every 10 seconds. It also obeys the CRKILLSWITCH.

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.

The “boinc_summary.dat” File

Example: fma_binary test Incomplete Job: Complete Job w/HASH: boinc_particles.dat, FMA_sixtrack, fort.10

SixTrack Version Characters to Validate Exit Status (if 100%) Progress in 1/100 000 CPU time in milliseconds

24 chars skipped rest is diffed

The “boinc_particles.dat” File

This file is just the standard final_state.dat file, but BOINC writes its own copy of it independent of what the user sets in their fort.3.
