Just to ask what is probably a FAQ to get it out here...
The Service Worker timeout is 30 seconds right, so regardless of how heavy the calculations are, a service worker and its associated calculations will die in 30 seconds after the user closes the associated page?
I ask because while it's been possible to run heavy calculations in various workers in the past, this explicitly encourages it. It would be a bad situation if a user cannot detect or stop a runaway WebGPU operation from a possibly hostile site.

Service Workers enable offline capabilities and background processing for WebGPU. This means graphics-intensive web applications or Chrome Extensions can cache resources and perform computations even when the user isn't actively interacting with the page. Shared Workers allow multiple tabs or extension contexts to coordinate and share WebGPU resources. This leads to smoother performance and more efficient use of the user's graphics hardware.Specification https://gpuweb.github.io/gpuweb/#navigator-gpu Summary Functionality added to the WebGPU spec after its first shipment in a browser.

None Debuggability None Will this feature be supported on all six Blink platforms (Windows, Mac, Linux, ChromeOS, Android, and Android WebView)? No All platforms will eventually have support. Will immediately be available on Android, ChromeOS, Mac, and Windows, since those platforms already support WebGPU. Linux is planned to have WebGPU support in the future, so this feature will become available when WebGPU does.What about WebView? Do we ship support for WebGPU there? Yes. WebGPU is supported on Android WebView as well.Note that Shared Workers are not available on Android for now. See https://issues.chromium.org/issues/40290702Is this feature fully tested by web-platform-tests <https://chromium.googlesource.com/chromium/src/+/main/docs/testing/web_platform_tests.md>? Yes WebGPU/WGSL have a conformance test suite (https://github.com/gpuweb/cts) that is regularly pulled into Chromium and part of the testing of Dawn/Tint in Chromium.
