# 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
Topic area | System
Values |
-2 | Highest supported [Generic, SSE2, AVX or AVX2], that is, using AVX2 instructions if supported by the CPU.
-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 | -2
Note | Generic code, SSE2 and AVX optimized code will all result in the same solution path, regardless of the operating system. The solution paths of AVX2 runs are also the same, regardless of the operating system. Using AVX2 or NEON might result in a solution path that is different from the AVX path.
Affects routines | XPRSlpoptimize ( LPOPTIMIZE), XPRSmipoptimize ( MIPOPTIMIZE).
