UBDA USEr 3

A. HPC Service (Effective from 1 September 2020)

Charge Type  Charging Unit Unit Charge (HKD) 
    PolyU User  Collaborator  External User 
CPU CPU core-hour  0.11 0.22 1.1
GPU GPU card-hour 2.2 4.4 22
Storage 100 GB-month 2.3 4.6 23

1. UBDA reserves the right determine whether a user should be charged as PolyU User, Collaborators or External User.

2. Users of current PolyU staff and students with a valid PolyU NETID is regarded as “PolyU Users”.

3. Users from other UGC-funded tertiary institutions and users form companies with ongoing collaborative projects with principal investigators at PolyU is regarded as “Collaborators”.

4. Users from commercial companies without ongoing collaborators with PolyU is regarded as “External Users”.

5. All charging rates are subject to change without prior notice. Users should refer to the latest version of this charging scheme, which is available on UBDA webpage (https://www.polyu.edu.hk/ubda).

6. Charging model will be reviewed yearly.

 

Assume a user has 200GB storage quota and using the 5,000 HKD free quota, a user can use the resources in the following manner.

For example,

Running a job continuously with 100 CPU cores for 18 days

Charge Type Qty Fee (HKD)
CPU fee# 100 CPU-core 4752
Storage (for 1 month) 200 GB 4.6

#CPU fee = 100 CPU core * 24 hours * 18 days * 0.11 HKD  = 4752HKD 

Running a job continuously with 10 CPU cores for 6 months

Charge Type Qty Fee (HKD)
CPU fee## 10 CPU-core 4752
Storage (for 1 month) 200 GB 4.6

##CPU fee = 10 CPU core * 24 hours * 6 months(180 days) * 0.11 HKD = 4752 HKD 

Running job with 16 CPU cores and 4 GPUs for 19 days

Charge Type Qty Fee (HKD)
CPU fee### 16 CPU-core 802.56
GPU fee@ 4 GPU-card 4012.8
Storage (for 1 month) 200 GB 4.6

###CPU fee = 16 CPU-core * 24 hours * 19 days * 0.11 HKD = 802.56 HKD
@GPU fee = 4 GPU-card * 24 hours * 19 days * 2.2 HKD = 4012.8 HKD
