Hi All,
Here I provide you more specific scenario.
For your information, the below case has been performed and the scenario is as follows:
- I have only 1 machine (local machine).
Then I have submitted a simple job to my local machine.
According to the Condor manual page, the RUP formula is as follows:
3.4.4 Priority Calculation
The RUP of a user u at time t, pi_r(u,t), is calculated every time interval delta t using the formula
pi_r(u,t) = beta * pi(u,t-delta t) + (1-beta) * rho(u,t)
where rho(u,t) is the number of resources used by user u at time t, and beta=0.5^(delta t/h). h is the half life period set by PRIORITY_HALFLIFE .
The EUP of user u at time t, pi_e(u,t) is calculated by
pi_e(u,t) = pi_r(u,t) * f(u,t)
where f(u,t) is the priority boost factor for user u at time t.
Fyi, to make it easier for me to monitor the user priorities, I have configured the PRIORITY_HALFLIFE = 600 (10 minutes).
Here I attach the accountantnew.log file from Condor:
# Condor Accountantnew.log File
103 Customer.21004@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx Priority 0.500000
105
103 Customer.21004@xxxxxxxxxxxxxxxxx ResourcesUsed 1

103 Accountant. LastUpdateTime 1214440307

103 Customer.21004@xxxxxxxxxxxxxxxxx Priority 0.646447
103 Customer.21004@xxxxxxxxxxxxxxxxx AccumulatedUsage 900.000000
103 Customer.21004@xxxxxxxxxxxxxxxxx LastUsageTime 1214440307
103 Customer.21004@xxxxxxxxxxxxxxxxx UnchargedTime 0
According to the above log file, the Priority value before the job has been submitted is 0.5 and on the next 10 minutes, Condor has updated to the new value = 0.646447.
Can u guide me how the priority value has been calculated according to the RUP formula?
This is my own understanding on the RUP formula and the result I got is as follows:
RUP -> pi_r(u,t) = beta * pi(u,t-delta t) + (1-beta) * rho(u,t) Where
Delta t = t2-t1 = 1200 - 600 = 600 (Is this correct?) H = 600 Beta = 0.5^(delta t/h) = 0.5^(600/600) = 0.5^1 = 0.5 pi(u,t-delta t) = The priority value in the previous timeframe. I believe the value is 0.5 (Is this also correct?)
rho(u,t) = resource used during time t = 1
RUP -> pi_r(u,t) = 0.5 * 0.5 + (1-0.5) * 1 = 0.25 + 0.5 = 0.75
According to the final calculation, I am supposed to get the Priority value = 0.646447 (based on the log file) instead of 0.75 (my own calculation).
Please guide and correct me on the calculation that I have been made on the RUP.
Any helps from you guys are highly appreciated!
Thanks.
