+Automation wrapper for linpack
+
+Description:
+         The Linpack Benchmark is a measure of a computer's floating-point rate of execution.
+         It is determined by running a computer program that solves a dense system of linear
+         equations.
+
+Location of useful documentation: https://www.netlib.org/utk/people/JackDongarra/faq-linpack.html
+Location of underlying workload: Requires the licensed linpack kit.
+
+Packages required: bc,numactl
+
+To run:
+```
+[root@hawkeye ~]# git clone https://github.com/redhat-performance/linpack-wrapper
+[root@hawkeye ~]# linpack-wrapper/linpack/linpack_run
+```
+
+
+```
+Options
+linpack Usage:
+  --interleave: numactl interleave option
+  --use_pbench_version: Instead of running the wrappers version
+    of linpack, use pbench-linpack when pbench is requested
+
+General options
+  --home_parent <value>: Our parent home directory.  If not set, defaults to current working directory.
+  --host_config <value>: default is the current host name.
+  --iterations <value>: Number of times to run the test, defaults to 1.
+  --pbench: use pbench-user-benchmark and place information into pbench, defaults to do not use.
+  --pbench_user <value>: user who started everything. Defaults to the current user.
+  --pbench_copy: Copy the pbench data, not move it.
+  --pbench_stats: What stats to gather. Defaults to all stats.
+  --run_label: the label to associate with the pbench run. No default setting.
+  --run_user: user that is actually running the test on the test system. Defaults to user running wrapper.
+  --sys_type: Type of system working with, aws, azure, hostname.  Defaults to hostname.
+  --sysname: name of the system running, used in determining config files.  Defaults to hostname.
+  --tuned_setting: used in naming the tar file, default for RHEL is the current active tuned.  For non

+  --usage: this usage message.
+```
