Controls the level of detail for the HPL output.
An integer ranging from 0 to 2:
Specifies cores or Non-Uniform Memory Access (NUMA) nodes to be used.
HPL_HOST_NODErequires NUMA mode to be enabled. You can check whether it is enabled by the

Behavior of the Intel Distribution for LINPACK Benchmark
All Intel Xeon processors in the cluster are used.
Intel Xeon processor cores 1,2,3,8,9, and 10 are used.
Only Intel Xeon processor cores on NUMA node 1 are used.
Intel's compilers may or may not optimize to the same degree for non-Intel microprocessors for optimizations that are not unique to Intel microprocessors. These optimizations include SSE2, SSE3, and SSSE3 instruction sets and other optimizations. Intel does not guarantee the availability, functionality, or effectiveness of any optimization on microprocessors not manufactured by Intel. Microprocessor-dependent optimizations in this product are intended for use with Intel microprocessors. Certain optimizations not specific to Intel microarchitecture are reserved for Intel microprocessors. Please refer to the applicable product User and Reference Guides for more information regarding the specific instruction sets covered by this notice.
