|
| -# 2.22x RC4 tune-up:-) It should be noted though that my hand [as in
|
| -# "hand-coded assembler"] doesn't stand for the whole improvement
|
| -# coefficient. It turned out that eliminating RC4_CHAR from config
|
| -# line results in ~40% improvement (yes, even for C implementation).
|
| -# Presumably it has everything to do with AMD cache architecture and
|
| -# RAW or whatever penalties. Once again! The module *requires* config
|
| -# line *without* RC4_CHAR! As for coding "secret," I bet on partial
|
| -# register arithmetics. For example instead of 'inc %r8; and $255,%r8'
|
| -# I simply 'inc %r8b'. Even though optimization manual discourages
|
| -# to operate on partial registers, it turned out to be the best bet.
|
| -# At least for AMD... How IA32E would perform remains to be seen...
|
| -
|
| -# November 2004
|
| -#
|
| -# As was shown by Marc Bevand reordering of couple of load operations
|
| -# results in even higher performance gain of 3.3x:-) At least on
|
| -# Opteron... For reference, 1x in this case is RC4_CHAR C-code
|
| -# compiled with gcc 3.3.2, which performs at ~54MBps per 1GHz clock.
|
| -# Latter means that if you want to *estimate* what to expect from
|
| -# *your* Opteron, then multiply 54 by 3.3 and clock frequency in GHz.
|
| -
|
| -# November 2004
|
| -#
|
| -# Intel P4 EM64T core was found to run the AMD64 code really slow...
|
| -# The only way to achieve comparable performance on P4 was to keep
|
| -# RC4_CHAR. Kind of ironic, huh? As it's apparently impossible to
|
| -# compose blended code, which would perform even within 30% marginal
|
| -# on either AMD and Intel platforms, I implement both cases. See
|
| -# rc4_skey.c for further details...
|
| -
|
| -# April 2005
|
| -#
|
| -# P4 EM64T core appears to be "allergic" to 64-bit inc/dec. Replacing
|
| -# those with add/sub results in 50% performance improvement of folded
|
| -# loop...
|
| -
|
| -# May 2005
|
| -#
|
| -# As was shown by Zou Nanhai loop unrolling can improve Intel EM64T
|
| -# performance by >30% [unlike P4 32-bit case that is]. But this is
|
| -# provided that loads are reordered even more aggressively! Both code
|
| -# pathes, AMD64 and EM64T, reorder loads in essentially same manner
|
| -# as my IA-64 implementation. On Opteron this resulted in modest 5%
|
| -# improvement [I had to test it], while final Intel P4 performance
|
| -# achieves respectful 432MBps on 2.8GHz processor now. For reference.
|
| -# If executed on Xeon, current RC4_CHAR code-path is 2.7x faster than
|
| -# RC4_INT code-path. While if executed on Opteron, it's only 25%
|
| -# slower than the RC4_INT one [meaning that if CPU µ-arch detection
|
| -# is not implemented, then this final RC4_CHAR code-path should be
|
| -# preferred, as it provides better *all-round* performance].
|
| -
|
| -# March 2007
|
| -#
|
| -# Intel Core2 was observed to perform poorly on both code paths:-( It
|
| -# apparently suffers from some kind of partial register stall, which
|
| -# occurs in 64-bit mode only [as virtually identical 32-bit loop was
|
| -# observed to outperform 64-bit one by almost 50%]. Adding two movzb to
|
| -# cloop1 boosts its performance by 80%! This loop appears to be optimal
|
| -# fit for Core2 and therefore the code was modified to skip cloop8 on
|
| -# this CPU.
|
| -
|
| -# May 2010
|
| -#
|
| -# Intel Westmere was observed to perform suboptimally. Adding yet
|
| -# another movzb to cloop1 improved performance by almost 50%! Core2
|
| -# performance is improved too, but nominally...
|
| -
|
| -# May 2011
|
| -#
|
| -# The only code path that was not modified is P4-specific one. Non-P4
|
| -# Intel code path optimization is heavily based on submission by Maxim
|
| -# Perminov, Maxim Locktyukhin and Jim Guilford of Intel. I've used
|
| -# some of the ideas even in attempt to optmize the original RC4_INT
|
| -# code path... Current performance in cycles per processed byte (less
|
| -# is better) and improvement coefficients relative to previous
|
| -# version of this module are:
|
| -#
|
| -# Opteron 5.3/+0%(*)
|
| -# P4 6.5
|
| -# Core2 6.2/+15%(**)
|
| -# Westmere 4.2/+60%
|
| -# Sandy Bridge 4.2/+120%
|
| -# Atom 9.3/+80%
|
| -#
|
| -# (*) But corresponding loop has less instructions, which should have
|
| -# positive effect on upcoming Bulldozer, which has one less ALU.
|
| -# For reference, Intel code runs at 6.8 cpb rate on Opteron.
|
| -# (**) Note that Core2 result is ~15% lower than corresponding result
|
| -# for 32-bit code, meaning that it's possible to improve it,
|
| -# but more than likely at the cost of the others (see rc4-586.pl
|
| -# to get the idea)...
