# Written by Andy Polyakov <appro@fy.chalmers.se> for the OpenSSL

# CRYPTOGAMS licenses depending on where you obtain it. For further

|
# Performance improvement is not really impressive on pre-T1 CPU: +8%
|
||
|
|
# over Sun C and +25% over gcc [3.3]. While on T1, a.k.a. Niagara, it
|
||
|
|
# turned to be 40% faster than 64-bit code generated by Sun C 5.8 and
|
||
|
|
# >2x than 64-bit code generated by gcc 3.4. And there is a gimmick.
|
||
|
|
# X[16] vector is packed to 8 64-bit registers and as result nothing
|
||
|
|
# is spilled on stack. In addition input data is loaded in compact
|
||
|
|
# instruction sequence, thus minimizing the window when the code is
|
||
|
|
# subject to [inter-thread] cache-thrashing hazard. The goal is to
|
||
|
|
# ensure scalability on UltraSPARC T1, or rather to avoid decay when
|
||
|
|
# amount of active threads exceeds the number of physical cores.
|
||
|
|
|
||
|
|
# SPARC T4 SHA1 hardware achieves 3.72 cycles per byte, which is 3.1x
|
||
|
|
# faster than software. Multi-process benchmark saturates at 11x
|
||
|
|
# single-process result on 8-core processor, or ~9GBps per 2.85GHz
|
||
|
|
# socket.
