If it is advisable run an embarrassingly parallel batch processing workload, it may be tough to determine what number of cases to create in every zone whereas accounting for accessible assets, quota limits and your reservations. We’re excited to announce a brand new technique of acquiring Compute Engine cases for batch processing that accounts for availability of assets in zones of a area. Now accessible in preview for regional managed instance groups, you are able to do this just by specifying the ANY worth within the API.

The capacity-aware deployment technique is especially helpful if it is advisable simply create many cases with a particular configuration similar to digital machines (VM) with a selected CPU platform or GPU mannequin, preemptible VMs, or cases with a lot of cores or reminiscence measurement.

Now, when deploying cases to run embarrassingly parallel batch processing, similar to monetary modeling or rendering, you now not have to determine which zones support the required {hardware} and what number of cases to create in every zone in a area to accommodate the requested capability.

Assuming that any distribution of cases throughout zones works on your batch processing job, and that the workload doesn’t require resilience in opposition to zone-level failure, now you can delegate the job of acquiring the requested capability to a regional managed occasion group. A regional MIG with the brand new distribution form ANY mechanically deploys cases to zones the place assets can be found to satisfy your request, accounting on your quota limits. This works each whenever you create a bunch or whenever you improve it in measurement.

In the event you use reservations to make sure that assets can be found on your computation, it is best to specify reservation affinity in a bunch’s instance template. A regional MIG with distribution form ANY makes use of the desired reservations effectively by prioritizing consumption of unused reserved capability earlier than provisioning further assets.
