In cloud database, a monthly quota for compute usage is assigned to each user. When you run simulations, InfoWorks WS Pro checks the monthly balance to see:
- What percentage of your monthly quota has been used for running cloud simulations. An email will be automatically sent when you reach 50%, 80% and 100% of your monthly quota.
- Whether or not your quota is exceeded.
When the quota used is exceeded, a message will appear after clicking the Run/Re-Run button in Schedule Hydraulic Run view that "you have used your monthly quota for simulation in the cloud. Your simulations will still be run in the cloud, but for the remainder of this month they will be queued sequentially and not run in parallel."
If the monthly quota is exceeded, simulations will still be run but in sequence rather than simultaneously (in parallel). When the quota is reset at the start of the next month, jobs will be processed in parallel until the monthly quota is reached.
Quota not exceeded
If your quota is not exceeded, the simulation jobs are pre-processed locally and then uploaded immediately to the cloud. They are queued in the cloud waiting for available instances, which then process the jobs in parallel.
Quota exceeded
If the quota is exceeded, a message is displayed warning you that the simulations jobs run will be in sequence rather than in parallel.
This means that the jobs will be pre-processed locally as normal, and then put in a local agent job queue rather than being immediately uploaded to the cloud. Each job is only uploaded when the previous job is complete (in sequence).
The status of a queued job is set to Waiting (compute restricted) in the Job View window. For example:
When a job is uploaded, it is processed when an instance becomes available. When complete, the next job is uploaded and then processed when an instance becomes available, and so on until all the jobs in the local agent queue are complete.
When the quota is reset at the start of the next calendar month (midnight UTC), any jobs already in the queue, and any new jobs, will be processed in parallel until the monthly simulation quota is reached.
