# ====================================================================
|
|
# Written by Andy Polyakov <appro@openssl.org> for the OpenSSL
|
|
# project. The module is, however, dual licensed under OpenSSL and
|
|
# CRYPTOGAMS licenses depending on where you obtain it. For further
|
|
# details see http://www.openssl.org/~appro/cryptogams/.
|
|
# ====================================================================
|
|
|
|
# SHA256/512 for PowerISA v2.07.
|
|
#
|
|
# Accurate performance measurements are problematic, because it's
|
|
# always virtualized setup with possibly throttled processor.
|
|
# Relative comparison is therefore more informative. This module is
|
|
# ~60% faster than integer-only sha512-ppc.pl. To anchor to something
|
|
# else, SHA256 is 24% slower than sha1-ppc.pl and 2.5x slower than
|
|
# hardware-assisted aes-128-cbc encrypt. SHA512 is 20% faster than
|
|
# sha1-ppc.pl and 1.6x slower than aes-128-cbc. Another interesting
|
|
# result is degree of computational resources' utilization. POWER8 is
|
|
# "massively multi-threaded chip" and difference between single- and
|
|
# maximum multi-process benchmark results tells that utlization is
|
|
# whooping 94%. For sha512-ppc.pl we get [not unimpressive] 84% and
|
|
# for sha1-ppc.pl - 73%. 100% means that multi-process result equals
|
|
# to single-process one, given that all threads end up on the same
|
|
# physical core.
