By default AVX512 instructions won’t be used whether the processor supports it or not unless -Z argument is added explicitly to the command line. With MLC v3.7 release onwards, only one binary is provided which supports SSE2, AVX2 and AVX512 instructions. mlc_avx512 was compiled with newer tool chain to support AVX512 instructions while mlc binary supported SSE2 and AVX2 instructions. Previous releases of MLC s/w provided two sets of binaries (mlc and mlc_avx512). The mlcdrv.sys driver is used to modify the h/w prefetcher settings. Copy mlc.exe and mlcdrv.sys driver to the same directory.This can typically be done with 'modprobe msr' command if it is not already included. MSR driver (not part of the install package) should be loaded.Refer readme documentation on running without root privileges Root privileges are required to run this tool as the tool modifies the H/W prefetch control MSR to enable/disable prefetchers for latency and b/w measurements.Intel® MLC dynamically links to GNU C library (glibc/lpthread) and this library must be present on the system.Copy the mlc binary to any directory on your system.Intel® MLC supports both Linux and Windows. New option -memory_bandwidth_scan (supported only on Linux) to be able to measure memory bandwidth over the entire address range in 1GB chunks.Support for 3rd Generation Intel® Xeon® Scalable Processors.It also provides several options for more fine-grained investigation where b/w and latencies from a specific set of cores to caches or memory can be measured as well. Intel® Memory Latency Checker (Intel® MLC) is a tool used to measure memory latencies and b/w, and how they change with increasing load on the system. So, measuring these latencies and b/w is important to establish a baseline for the system under test, and for performance analysis. Besides latency, bandwidth (b/w) also plays a big role in determining performance. In a multi-socket system where Non-Uniform Memory Access (NUMA) is enabled, local memory latencies and cross-socket memory latencies will vary significantly.
