TESTS SCENARIOS
|
|
===============
|
|
|
|
memkind-afts
|
|
------------
|
|
This is scenario for basic functional tests. Maximum number of allocations per numa node:
|
|
- 512 x 4KB pages (summary: 2GB)
|
|
- 16 x 2MB pages
|
|
|
|
memkind-afts-ext
|
|
----------------
|
|
The same tests as in memkind-afts, however this tests are more ravenous and needs more memory
|
|
available. Special test cases prepared only for this scenario are described as ravenous
|
|
and needs at least:
|
|
- 512 x 4KB pages (summary: 2GB)
|
|
- 16 x 2MB pages
|
|
memory available per numa node.
|
|
|
|
memkind-perf
|
|
------------
|
|
This is scenario for performance tests, excluding tests that allocate more than:
|
|
- 512 x 4KB pages (summary: 2GB)
|
|
- 16 x 2MB pages
|
|
|
|
memkind-perf-ext
|
|
----------------
|
|
This test scenario extend memkind-perf for tests that allocate more than:
|
|
- 512 x 4KB pages (summary: 2GB)
|
|
- 16 x 2MB pages
|
|
AllocPerformanceTest is a group of performance tests for *alloc() execution. TC properties:
|
|
- 6 kinds (MEMKIND_DEFAULT, MEMKIND_HBW, MEMKIND_INTERLEAVE, MEMKIND_HBW_INTERLEAVE, MEMKIND_HBW_PREFERRED, PMEM kind)
|
|
- 3 calls (malloc, calloc, realloc)
|
|
- 5 allocation sizes (100bytes, 4096bytes, 1000bytes, 1001bytes, 1.5MB - 1572864bytes)
|
|
- single thread and multithreaded (10threads and 72threads)
|
|
All tests record three values:
|
|
- total_time_spend_on_alloc (total time spend on *alloc() call during the test - less is better)
|
|
- alloc_operations_per_thread (number of done allocations per thread - this value is constant)
|
|
- ref_delta_time_percent (percent delta between standard allocator and current tested kind - less is better)
|
|
|
|
memkind-slts
|
|
------------
|
|
This is scenario for all stress and longevity tests.
|
|
|
|
|
|
MANUAL TESTING
|
|
==============
|
|
In order to run tests on local machine, test.sh should be executed.
|
|
When test.sh is run, all tests are executed as long as -d (skip MCDRAM nodes detection), -m (skip
|
|
tests that require 2MB pages) parameters are not used.
