The cpu simd command tests multimedia extensions. For every logical processor, next multimedia extensions are tested. For example: MMX, SSE, SSE3, SSSE3, SSE4.1, SSE4.2, and AVX. This command tests the Simple Input Multiple Data (SIMD) Intel Instruction set. Small algorithms are executed using respective instructions. Without options, testing is executed on the boot strap processor.
