mubench Publisher's description
from Alex Izvorski
mubench is an in-depth, low-level benchmark for x86 processors.
mubench is an in-depth, low-level benchmark for x86 processors. Its primary goal is to provide useful information for people who optimize assembly code and for people who write compilers. It measures latency and throughput for each individual instruction (sometimes several forms of the same instruction), as well as the throughput of arbitrary instruction mixes. The results produced by mubench are typically an order of magnitude more detailed than those found in AMD or Intel manuals.
mubench results for a variety of processors are available. If you find this information useful, please run mubench on your processor and upload the results.
mubench fully supports all SIMD instruction sets for the x86, including SSSE3, SSE3, SSE2, SSE, MMX, MMX Ext, 3DNow! and 3DNow! Ext. Support for non-SIMD instructions is partial: most data move, binary arithmetic, logical, shift/rotate and bit/byte instructions are supported, but other instructions, particularly branch and function call instructions or instructions manipulating the stack, are not supported. Floating-point instructions for the x87 are not supported. mubench only uses register-to-register (or immediate) forms of the instructions; memory operands are not supported. These limitations will be gradually removed in later releases.
What's New in This Release:. the fast form of the benchmark is now default.
. gcc 4.x now works
. a number of non-simd instructions added, support for non-simd is much closer to complete now
System Requirements:No special requirements.
Program Release Status: Minor Update
Program Install Support: Install and Uninstall
