Usage

membw [OPTIONS] [OPERATION]

Overview

The membw software tool provides a way to stress local and remote memory bandwidth using a variety of memory operations. The tool allows the user to choose an operation to generate a specified amount of memory bandwidth on a selected core.

Options

membw options are as follow:

--help: show help

-c, --cpu: cpu to generate B/W

-b, --bandwidth: memory B/W specified in MBps

Operation

`--prefetch-t0`	prefetcht0
`--prefetch-t1`	prefetcht1
`--prefetch-t2`	prefetcht2
`--prefetch-nta`	prefetchtnta
`--prefetch-w`	prefetchw
`--read`	x86 loads
`--read-sse`	SSE loads
`--nt-read-sse`	SSE NT loads
`--read-mod-write`	x86 load XOR write
`--write`	x86 stores
`--write-avx512`	AVX512 stores
`--write-clwb`	x86 stores + clwb
`--write-flush`	x86 stores & clflush (naturally generates loads & stores)
`--write-sse`	SSE stores
`--write-sse-flush`	SSE stores & clflush (naturally generates loads & stores)
`--nt-write`	x86 NT stores
`--nt-write-avx512`	AVX512 NT stores
`--nt-write-clwb`	x86 NT stores + clwb
`--nt-write-sse`	SSE NT stores
