Calculating Fairshare - bhpart

Typical Fairshare Formula:

dynamic_priority = number_shares / (cpu_time * CPU_TIME_FACTOR + run_time * RUN_TIME_FACTOR + (1 + job_slots) * RUN_JOB_FACTOR + fairshare_adjustment*FAIRSHARE_ADJUSTMENT_FACTOR).

For your case, it will be:

Dynamic_priority = number_share / (cpu_time * 0.7 + run_time * 0.7  + (1 + job_slots) * 3)

The only trick here is that internal calculation uses hour as unit for cpu_time and run_time value, but the bhpart display values are in second. So, ultimately, the formula will become:

Dynamic_priority = number_share / (bhpart_cpu_time/3600 * 0.7 + bhpart_run_time/3600 * 0.7  + (1 + job_slots) * 3)

Lets give a try:

USER/GROUP   SHARES  PRIORITY  STARTED  RESERVED  CPU_TIME  RUN_TIME   ADJUST
navarrop     1000       9.031     4        0    205487.2   286841       0.000

So, dynamic_priority = 1000 / (205487.2 / 3600 * 0.7 + 286841 / 3600 * 0.7 + (1 + 4) * 3)
                                          = 1000 / (39.95 + 55.77 + 15)
                                          = 1000/ 110.72
                                          = 9.031
