There already is a test to verify the mempool sharding works, in the sense that it uses at least half of the variables available to count the number of allocated objects and their total size. This new test verifies that, with sharding, object counting is at least twice faster than without sharding. It also collects cacheline contention data with the perf c2c tool. The manual analysis of this data shows the optimization gain is indeed related to cacheline contention. Fixes: https://tracker.ceph.com/issues/49896 Signed-off-by: Loïc Dachary <loic@dachary.org> |

ceph-qa-suite ------------- clusters/ - some predefined cluster layouts suites/ - set suite The suites directory has a hierarchical collection of tests. This can be freeform, but generally follows the convention of suites/<test suite name>/<test group>/... A test is described by a yaml fragment. A test can exist as a single .yaml file in the directory tree. For example: suites/foo/one.yaml suites/foo/two.yaml is a simple group of two tests. A directory with a magic '+' file represents a test that combines all other items in the directory into a single yaml fragment. For example: suites/foo/bar/+ suites/foo/bar/a.yaml suites/foo/bar/b.yaml suites/foo/bar/c.yaml is a single test consisting of a + b + c. A directory with a magic '%' file represents a test matrix formed from all other items in the directory. For example, suites/baz/% suites/baz/a.yaml suites/baz/b/b1.yaml suites/baz/b/b2.yaml suites/baz/c.yaml suites/baz/d/d1.yaml suites/baz/d/d2.yaml is a 4-dimensional test matrix. Two dimensions (a, c) are trivial (1 item), so this is really 2x2 = 4 tests, which are a + b1 + c + d1 a + b1 + c + d2 a + b2 + c + d1 a + b2 + c + d2 A directory with a magic '$' file, or a directory whose name ends with '$', represents a test where one of the non-magic items is chosen randomly. For example, both suites/foo/$ suites/foo/a.yaml suites/foo/b.yaml suites/foo/c.yaml and suites/foo$/a.yaml suites/foo$/b.yaml suites/foo$/c.yaml is a single test, either a, b or c. This can be used in conjunction with the '%' file in the same (see below) or other directories to run a series of tests without causing an unwanted increase in the total number of jobs run. Symlinks are okay. One particular use of symlinks is to combine '%' and the latter form of '$' feature. Consider supported_distros directory containing fragments that define os_type and os_version: supported_distros/% supported_distros/centos.yaml supported_distros/rhel.yaml supported_distros/ubuntu.yaml A test that links supported_distros as distros (a name that doesn't end with '$') will be run three times: on centos, rhel and ubuntu. A test that links supported_distros as distros$ will be run just once: either on centos, rhel or ubuntu, chosen randomly. The teuthology code can be found in https://github.com/ceph/teuthology.git
