NAME

       membw - tool for generating memory bandwidth

SYNOPSIS

       membw [OPTIONS][OPERATION]

DESCRIPTION

       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
