10 # ====================================================================
12 # SHA256 performance improvement over compiler generated code varies
13 # from 40% for Sun C [32-bit build] to 70% for gcc [3.3, 64-bit
14 # build]. Just like in SHA1 module I aim to ensure scalability on
15 # UltraSPARC T1 by packing X[16] to 8 64-bit registers.
17 # SHA512 on pre-T1 UltraSPARC.
19 # Performance is >75% better than 64-bit code generated by Sun C and
20 # over 2x than 32-bit code. X[16] resides on stack, but access to it
21 # is scheduled for L2 latency and staged through 32 least significant
22 # bits of %l0-%l7. The latter is done to achieve 32-/64-bit ABI
23 # duality. Nevetheless it's ~40% faster than SHA256, which is pretty
24 # good [optimal coefficient is 50%].
26 # SHA512 on UltraSPARC T1.
28 # It's not any faster than 64-bit code generated by Sun C 5.8. This is
29 # because 64-bit code generator has the advantage of using 64-bit
30 # loads(*) to access X[16], which I consciously traded for 32-/64-bit
31 # ABI duality [as per above]. But it surpasses 32-bit Sun C generated
32 # code by 60%, not to mention that it doesn't suffer from severe decay
33 # when running 4 times physical cores threads and that it leaves gcc
34 # [3.4] behind by over 4x factor! If compared to SHA256, single thread
35 # performance is only 10% better, but overall throughput for maximum
36 # amount of threads for given CPU exceeds corresponding one of SHA256
37 # by 30% [again, optimal coefficient is 50%].
39 # (*) Unlike pre-T1 UltraSPARC loads on T1 are executed strictly
40 # in-order, i.e. load instruction has to complete prior next
41 # instruction in given thread is executed, even if the latter is
42 # not dependent on load result! This means that on T1 two 32-bit
43 # loads are always slower than one 64-bit load. Once again this
44 # is unlike pre-T1 UltraSPARC, where, if scheduled appropriately,
45 # 2x32-bit loads can be as fast as 1x64-bit ones.
47 # SPARC T4 SHA256/512 hardware achieves 3.17/2.01 cycles per byte,
48 # which is 9.3x/11.1x faster than software. Multi-process benchmark
49 # saturates at 11.5x single-process result on 8-core processor, or
50 # ~11/16GBps per 2.85GHz socket.
