Previous Release Highlights

Brief summaries of new features in previous MMCloud releases.

Half Moon Bay 2.5 Release

The Half Moon Bay 2.5 release adds major features and improves the overall reliability and scalability of the platform.

  • SurfZone is a cost management feature that allows an administrator to configure a monthly budget (quota) for a group of users. If the spending limit is reached, jobs are canceled immediately or suspended until the budget is replenished. The choice to cancel or suspend is a configuration option. If the job is suspended, the SurfZone configuration determines whether the job resumes automatically when the budget is replenished or waits for user input.

  • Workflow view of jobs allows the user to examine all the tasks grouped in a single workflow. For example, there can be hundreds of tasks in a single Nextflow pipeline. In the web interface, the Workflow Details screen includes a summary of the entire pipeline, for example, wall time, CPU time, and the numbers of on-demand and spot instances created. A Timeline tab shows when individual jobs start and, if completed, when they stop. Current status is color-coded to indicate success, failure, running, and so on. This feature applies automatically to Nextflow pipelines and can be applied to other workflows by including identifying tags.

  • Multiple Machine Images is a feature (called Quiver) that enables the OpCenter to create VMs using VMIs (virtual machine images) that are specialized for the task, for example, to support an instance with a GPU. Previous versions of OpCenter software used the same VMI for all instances (based on CPUs with x86 architecture).

  • NVIDIA GPU support allows users to submit jobs that take advantage of the NVIDIA drivers and hardware. The NVIDIA GPU support in the Half Moon Bay release does not include checkpoint and restore, so SpotSurfer and WaveRider are not available for these jobs.

Goa 2.4 Release

The Goa 2.4 release adds two major features and a number of other product enhancements.

  • AppCapsule++ improves the snapshot feature to increase the size of the memory footprint that can be captured and to decrease the time that the application is "frozen" when the snapshot is taken. AppCapsule++ is only supported on AWS.
  • New license model eliminates the Essential plan and changes how users on the Pro plan are charged (instead of a percentage of savings, usage is charged at a fixed rate per CPU core hour). The new license plan is simpler and maps more accurately to how customers use MMCloud.

Other new features include additional functionality in the web interface (user management and system configuration), configuration options to improve performance (such as a compute instance deny list), and native Cloud Storage FUSE support for Google Cloud.

A job template to create a Script-of-Scripts (SOS) polyglot notebook server is added as a preview feature.
