+*************************************
+Yardstick Test Case Description TC010
+*************************************
++-----------------------------------------------------------------------------+
+|Memory Latency |
++==============+==============================================================+
+|test case id | OPNFV_YARDSTICK_TC010_Memory Latency |
++--------------+--------------------------------------------------------------+
+|metric | Latency in nanoseconds |
++--------------+--------------------------------------------------------------+
+|test purpose | Measure the memory read latency for varying memory sizes and |
+| | strides. Whole memory hierarchy is measured including all |
+| | levels of cache. |
++--------------+--------------------------------------------------------------+
+|configuration | File: opnfv_yardstick_tc010.yaml |
+| | |
+| | * SLA (max_latency): 30 nanoseconds |
+| | * Stride - 128 bytes |
+| | * Stop size - 64 megabytes |
+| | * Iterations: 10 - test is run 10 times iteratively. |
+| | * Interval: 1 - there is 1 second delay between each |
+| | iteration. |
++--------------+--------------------------------------------------------------+
+|test tool | Lmbench |
+| | |
+| | Lmbench is a suite of operating system microbenchmarks. This |
+| | test uses lat_mem_rd tool from that suite. |
+| | Lmbench is not always part of a Linux distribution, hence it |
+| | needs to be installed in the test image |
+| | (See :ref:`guest-image` for how to generate a Linux image |
+| | for Glance with Lmbench included). |

++--------------+--------------------------------------------------------------+
+|applicability | Test can be configured with different |
+| | * strides; |
+| | * stop_size; |
+| | * iterations and intervals; |
+| | |
+| | There are default values for each above-mentioned option. |
+| | |
+| | * SLA (optional). |
+| | max_latency: The maximum memory latency that is |
+| | accepted. |
++--------------+--------------------------------------------------------------+
+|pre-test | The test case image needs to be installed into Glance |
+|conditions | with Lmbench included in the image. |
+| | |
+| | No POD specific requirements have been identified. |
++--------------+------+----------------------------------+--------------------+
+|test sequence | step | description | result |
+| +------+----------------------------------+--------------------+
+| | 1 | The host is installed as client. | Logs are stored |
+| | | Lmbench's lat_mem_rd tool is | |
+| | | invoked and logs are produced and| |
+| | | stored. | |
++--------------+------+----------------------------------+--------------------+
+|test verdict | Test fails if the measured memory latency is above the SLA |
+| | value or if there is a test case execution problem. |
