	// WIDTH: number of bytes to load/store in one instruction for bandwidth tests
	// default: 32
	// WIDTH∊1 2 4 8: regular integer loads
	// x86-64 WIDTH==16 - SSE; WIDTH==32 - AVX2, WIDTH==64 - AVX-512
	// aarch64: WIDTH==16 - NEON loads; WIDTH==32 uses an ldp
	// UNALIGNED: number of bytes to misalign tested pointers by
	// CLOCK_RATE: number of clock cycles in a second on the target processor
	// TEST_LAT: test latency instead of bandwidth; latency tests aligned 8-byte loads
