**Invited Speaker:** Tom Nicholas (ORCID: [0000-0002-2176-0530](https://orcid.org/0000-0002-2176-0530)), Tom White  
**When:** Wednesday, Nov 15, 12PM EST  
**Where:** [Launch Meeting - Zoom](https://numfocus-org.zoom.us/j/83234473026?pwd=mgM3uAuru1AE1aFPlRjW2dAAAyo8IY.1)  
**Abstract:**  
Cubed is an alternative framework for distributed processing of large arrays. Designed to respect memory constraints at all times, Cubed generalises the model of Rechunker to execute any numpy-like array operation. By using Zarr as persistent storage between steps, and Lithops as an abstraction layer, Cubed can run in a serverless fashion on a range of Cloud platforms. We will show how Cubed has been integrated with Xarray and demonstrate its performance on a tricky array workload.
