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