On Sunday, March 18th, the Open MPI team is going to make a change in where nightly tarballs are stored that will likely impact MTT test configuration. If you have an automated system (including MTT) that fetches nightly tarballs, you will likely need to make a change in the next two weeks to avoid breakage.
Over the last year, we’ve been working behind the scenes to improve some of the workflows around building and releasing tarballs (both nightly and release), including moving them out of our web tree and into Amazon S3 (and the Amazon CloudFront CDN for downloads). It’s time to make the next step, moving the nightly tarballs out of the web tree. As of December, the nightly tarball builder uploads the build results to S3, which can be accessed from: https://download.open-mpi.org/nightly/open-mpi/<release branch>/<tarball name> So to get the latest 3.0 nightly tarball version, you’d download https://download.open-mpi.org/nightly/open-mpi/v3.0.x/latest_snapshot.txt. The build artifact tree under https://download.open-mpi.org/nightly/open-mpi/ matches the tree under https://www.open-mpi.org/nightly/, so scripts should work with only the change in root of the tree. On Sunday, March 18th, we’ll stop mirroring tarballs to www.open-mpi.org and rewrite the web pages to direct users to download.open-mpi.org/ for downloading nightly tarballs of Open MPI. We will add redirects from the old tarballs and latest_snapshot.txt files to the new location, but not all clients follow redirects by default. So we’re asking everyone to proactively update their MTT scripts. It should just be updating lines like: ompi_snapshot_url = https://www.open-mpi.org/nightly/master to read: ompi_snapshot_url = https://download.open-mpi.org/nightly/open-mpi/master Thanks, Brian _______________________________________________ devel mailing list devel@lists.open-mpi.org https://lists.open-mpi.org/mailman/listinfo/devel
