CPUPLATFORM

Description
Newton Barrier: Selects the AMD, Intel x86 or ARM vectorization instruction set that Barrier should run optimized code for. On AMD / Intel x86 platforms the SSE2, AVX and AVX2 instruction sets are supported while on ARM platforms the NEON architecture extension can be activated.
Type
Integer
Values
-2 
Highest supported [Generic, SSE2, AVX or AVX2].
-1 
Highest supported solve path consistent code [Generic, SSE2 or AVX].
0 
Use generic code compatible with all CPUs.
1 
Use SSE2 / NEON optimized code.
2 
Use AVX optimized code.
3 
Use AVX2 optimized code.
Default value
-1
Note
Generic code, SSE2 and AVX optimized code will all result in the same solution path. Using AVX2 or NEON might result in a different solution path.
Affects routines
XPRSlpoptimize ( LPOPTIMIZE), XPRSmipoptimize ( MIPOPTIMIZE).
