What is Tapper? It's basically their version of the Phoronix Test Suite and Phoromatic. "Tapper is an open source infrastructure originating at AMD for all aspects of testing including Operating Systems and Virtualization. Its goal is to help QA departments to maintain a complete test life cycle from planning to execution and reporting. It provides independent modules to adapt to different levels of QA requirements, from simple tracking and presenting test results to complete automation of machine pools multiplexing complex virtualization use-cases with detailed data evaluation."
AMD's Tapper focuses upon test automation, machine scheduling, support for writing tests, etc. There's also CLI and web front-ends. Just like the Phoronix Test Suite, but it doesn't have as many test profiles/suites (haven't been able to find any tests that it actually ships with), but without any OpenBenchmarking.org equivalent.
Tapper does boast a few nice features though (all of which though can be hooked into PTS via modules) for PXE / GRUB / TFNP / NFS boot automation and Perl / Python interfaces. But in order to run a Tapper client, you must first setup a Tapper server, which requires a MySQL/SQLite database running, among other dependencies.
Those interested in learning more about AMD Tapper can find it in their open-source zone and the code is available in a few repositories off GitHub.
