6.4 Out-of-the-Box Large Memory Benchmark
To easily test the performance of the system, a large memory workload,
demonstrating multiplication of very large matrices, which is the corner stone of
many algorithms, leveraging Intel® Math Kernel Library (MKL) is provided.
The workload can be used to test system performance for:

Memory Replacement : Performing an apples-to-apples comparison of (1) a
Native (i.e. DRAM only) system, with (2) a system using lower DRAM
augmented with Ultrastar memory, where (2) would be a cost-effective
alternative to DRAM.

Memory Expansion : Validate that a workload with a memory footprint
higher than DRAM capacity can successfully execute with near-DRAM
performance by expanding the system memory with Ultrastar memory.
To perform the test:
1. If using version 9.0 or newer, run the test embedded in the installer:
# ./wmem_installer-9.0.3365.2.sh si -p s
2. Otherwise, a publicly available workload can be obtained and configured per
the following: github.com/ScaleMP/SEG_SGEMM
3. Run the workload on a Native (i.e. DRAM only) system, and collect the results.
4. Run the workload on a system with Ultrastar memory drive configured, and
collect the results.
