Hi All: We have an ultimatum to reduce (drastically) our usage of GitHub Actions. Or our Continuous Integration will halt totally in Two Weeks. Here's what I'll implement within 24 hours for `nuttx` and `nuttx-apps` repos:
(1) When we submit or update a Complex PR that affects All Architectures (Arm, RISC-V, Xtensa, etc): CI Workflow shall run only half the jobs. Previously CI Workflow will run `arm-01` to `arm-14`, now we will run only `arm-01` to `arm-07`. (This will reduce GitHub Cost by 32%) (2) When the Complex PR is Merged: CI Workflow will still run all jobs `arm-01` to `arm-14` (3) For NuttX Admins: We shall have only Four Scheduled Merge Jobs per day. Which means I shall quickly cancel any Merge Jobs that appear. Then at 00:00 / 06:00 / 12:00 / 18:00 UTC: I shall restart the Latest Merge Job that I cancelled. (This will reduce GitHub Cost by 17%) (4) macOS and Windows Jobs (msys2 / msvc): They shall be totally disabled until we find a way to manage their costs. (GitHub charges 10x premium for macOS runners, 2x premium for Windows runners!) We have done an Analysis of CI Jobs over the past 24 hours: - Many CI Jobs are Incomplete: We waste GitHub Runners on jobs that eventually get superseded and cancelled - When we Half the CI Jobs: We reduce the wastage of GitHub Runners - Scheduled Merge Jobs will also reduce wastage of GitHub Runners, since most Merge Jobs don't complete (only 1 completed yesterday) Please check out the analysis below. And let's discuss further in this NuttX Issue.
