Stream encoding provides CRC checks of data. + +It is possible to efficiently skip forward in a compressed stream using the `Skip()` method. +For big skips the decompressor is able to skip blocks without decompressing them. + +## Single Blocks + +Similar to Snappy S2 offers single block compression. +Blocks do not offer the same flexibility and safety as streams, +but may be preferable for very small payloads, less than 100K. + +Using a simple `dst := s2.Encode(nil, src)` will compress `src` and return the compressed result. +It is possible to provide a destination buffer. +If the buffer has a capacity of `s2.MaxEncodedLen(len(src))` it will be used. +If not a new will be allocated. + +Alternatively `EncodeBetter`/`EncodeBest` can also be used for better, but slightly slower compression. + +Similarly to decompress a block you can use `dst, err := s2.Decode(nil, src)`. +Again an optional destination buffer can be supplied. +The `s2.DecodedLen(src)` can be used to get the minimum capacity needed. +If that is not satisfied a new buffer will be allocated. + +Block function always operate on a single goroutine since it should only be used for small payloads. + +# Commandline tools + +Some very simply commandline tools are provided; `s2c` for compression and `s2d` for decompression. + +Binaries can be downloaded on the [Releases Page](https://github.com/klauspost/compress/releases). + +Installing then requires Go to be installed.

Chunks begin and end on byte boundaries. The +first byte of each chunk is broken into its 2 least and 6 most significant bits +called l and m: l ranges in [0, 4) and m ranges in [0, 64). l is the chunk tag. +Zero means a literal tag. All other values mean a copy tag. + +For literal tags: + - If m < 60, the next 1 + m bytes are literal bytes. + - Otherwise, let n be the little-endian unsigned integer denoted by the next + m - 59 bytes. The next 1 + n bytes after that are literal bytes. + +For copy tags, length bytes are copied from offset bytes ago, in the style of +Lempel-Ziv compression algorithms. In particular: + - For l == 1, the offset ranges in [0, 1<<11) and the length in [4, 12). + The length is 4 + the low 3 bits of m. The high 3 bits of m form bits 8-10 + of the offset.

This will result in reduced overall CPU load. + +It is important to understand that `md5-simd` **does not speed up** a single threaded MD5 hash sum. +Rather it allows multiple __independent__ MD5 sums to be computed in parallel on the same CPU core, +thereby making more efficient usage of the computing resources. + +## Usage + +[![Documentation](https://godoc.org/github.com/minio/md5-simd?status.svg)](https://pkg.go.dev/github.com/minio/md5-simd?tab=doc) + + +In order to use `md5-simd`, you must first create an `Server` which can be +used to instantiate one or more objects for MD5 hashing. + +These objects conform to the regular [`hash.Hash`](https://pkg.go.dev/hash?tab=doc#Hash) interface +and as such the normal Write/Reset/Sum functionality works as expected. + +As an example: +``` + // Create server + server := md5simd.NewServer() + defer server.Close() + + // Create hashing object (conforming to hash.Hash) + md5Hash := server.NewHash() + defer md5Hash.Close() + + // Write one (or more) blocks + md5Hash.Write(block) + + // Return digest + digest := md5Hash.Sum([]byte{}) +``` + +To keep performance both a [Server](https://pkg.go.dev/github.com/minio/md5-simd?tab=doc#Server) +and individual [Hasher](https://pkg.go.dev/github.com/minio/md5-simd?tab=doc#Hasher) should +be closed using the `Close()` function when no longer needed. + +A Hasher can efficiently be re-used by using [`Reset()`](https://pkg.go.dev/hash?tab=doc#Hash) functionality. + +In case your system does not support the instructions required it will fall back to using `crypto/md5` for hashing. + +## Limitations + +As explained above `md5-simd` does not speed up an individual MD5 hash sum computation, +unless some hierarchical tree construct is used but this will result in different outcomes. +Running a single hash on a server results in approximately half the throughput. + +Instead, it allows running multiple MD5 calculations in parallel on a single CPU core. +This can be beneficial in e.g. multi-threaded server applications where many go-routines +are dealing with many requests and multiple MD5 calculations can be packed/scheduled for parallel execution on a single core. + +This will result in a lower overall CPU usage as compared to using the standard `crypto/md5` +functionality where each MD5 hash computation will consume a single thread (core). + +It is best to test and measure the overall CPU usage in a representative usage scenario in your application +to get an overall understanding of the benefits of `md5-simd` as compared to `crypto/md5`, ideally under heavy CPU load. + +Also note that `md5-simd` is best meant to work with large objects, +so if your application only hashes small objects of a few kilobytes +you may be better of by using `crypto/md5`. + +## Performance + +For the best performance writes should be a multiple of 64 bytes, ideally a multiple of 32KB. +To help with that a [`buffered := bufio.NewWriterSize(hasher, 32<<10)`](https://golang.org/pkg/bufio/#NewWriterSize) +can be inserted if you are unsure of the sizes of the writes. +Remember to [flush](https://golang.org/pkg/bufio/#Writer.Flush) `buffered` before reading the hash. + +A single 'server' can process 16 streams concurrently with 1 core (AVX-512) or 2 cores (AVX2). +In situations where it is likely that more than 16 streams are fully loaded it may be beneficial +to use multiple servers. + +The following chart compares the multi-core performance between `crypto/md5` vs the AVX2 vs the AVX512 code: + +![md5-performance-overview](chart/Multi-core-MD5-Aggregated-Hashing-Performance.png) + +Compared to `crypto/md5`, the AVX2 version is up to 4x faster: + +``` +$ benchcmp

equipped with a Xeon Platinum 8124M CPU at 3.0 GHz. + + +## Operation + +To make operation as easy as possible there is a “Server” coordinating everything. The server keeps track of individual hash states and updates them as new data comes in. This can be visualized as follows: + +![server-architecture](chart/server-architecture.png) + +The data is sent to the server from each hash input in blocks of up to 32KB per round. In our testing we found this to be the block size that yielded the best results. + +Whenever there is data available the server will collect data for up to 16 hashes and process all 16 lanes in parallel. This means that if 16 hashes have data available all the lanes will be filled. However since that may not be the case, the server will fill less lanes and do a round anyway. Lanes can also be partially filled if less than 32KB of data is written. + +![server-lanes-example](chart/server-lanes-example.png) + +In this example 4 lanes are fully filled and 2 lanes are partially filled. In this case the black areas will simply be masked out from the results and ignored. This is also why calculating a single hash on a server will not result in any speedup and hash writes should be a multiple of 32KB for the best performance. + +For AVX512 all 16 calculations will be done on a single core, on AVX2 on 2 cores if there is data for more than 8 lanes. +So for optimal usage there should be data available for all 16 hashes. It may be perfectly reasonable to use more than 16 concurrent hashes. + + +## Design & Tech + +md5-simd has both an AVX2 (8-lane parallel), and an AVX512 (16-lane parallel version) algorithm to accelerate the computation with the following function definitions: +``` +//go:noescape +func block8(state *uint32, base uintptr, bufs *int32, cache *byte, n int) + +//go:noescape +func block16(state *uint32, ptrs *int64, mask uint64, n int) +``` + +The AVX2 version is based on the [md5vec](https://github.com/igneous-systems/md5vec) repository and is essentially unchanged except for minor (cosmetic) changes. + +The AVX512 version is derived from the AVX2 version but adds some further optimizations and simplifications. + +### Caching in upper ZMM registers + +The AVX2 version passes in a `cache8` block of memory (about 0.5 KB) for temporary storage of intermediate results during `ROUND1` which are subsequently used during `ROUND2` through to `ROUND4`. + +Since AVX512 has double the amount of registers (32 ZMM registers as compared to 16 YMM registers), it is possible to use the upper 16 ZMM registers for keeping the intermediate states on the CPU. As such, there is no need to pass in a corresponding `cache16` into the AVX512 block function. + +### Direct loading using 64-bit pointers + +The AVX2 uses the `VPGATHERDD` instruction (for YMM) to do a parallel load of 8 lanes using (8 independent) 32-bit offets. Since there is no control over how the 8 slices that are passed into the (Golang) `blockMd5` function are laid out into memory, it is not possible to derive a "base" address and corresponding offsets (all within 32-bits) for all 8 slices. + +As such the AVX2 version uses an interim buffer to collect the byte slices to be hashed from all 8 inut slices and passed this buffer along with (fixed) 32-bit offsets into the assembly code. + +For the AVX512 version this interim buffer is not needed since the AVX512 code uses a pair of `VPGATHERQD` instructions to directly dereference 64-bit pointers (from a base register address that is initialized to zero). + +Note that two load (gather) instructions are needed because the AVX512 version processes 16-lanes in parallel, requiring 16 times 64-bit = 1024 bits in total to be loaded. A simple `VALIGND` and `VPORD` are subsequently used to merge the lower and upper halves together into a single ZMM register (that contains 16 lanes of 32-bit DWORDS). + +### Masking support + +Due to the fact that pointers are passed directly from the Golang slices, we need to protect against NULL pointers. +For this a 16-bit mask is passed in the AVX512 assembly code which is used during the `VPGATHERQD` instructions to mask out lanes that could otherwise result in segment violations. + +### Minor optimizations + +The `roll` macro (three instructions on AVX2) is no longer needed for AVX512 and is replaced by a single `VPROLD` instruction. + +Also several logical operations from the various ROUNDS of the AVX2 version could be combined into a single instruction using ternary logic (with the `VPTERMLOGD` instruction), resulting in a further simplification and speed-up. + +## Low level block function performance + +The benchmark below shows the (single thread) maximum performance of the `block()` function for AVX2 (having 8 lanes) and AVX512 (having 16 lanes). Also the baseline single-core performance from the standard `crypto/md5` package is shown for comparison. + +``` +BenchmarkCryptoMd5-4 687.66 MB/s 0 B/op 0 allocs/op +BenchmarkBlock8-4 4144.80 MB/s 0 B/op 0 allocs/op +BenchmarkBlock16-4 8228.88 MB/s 0 B/op 0 allocs/op +``` + +## License + +`md5-simd` is released under the Apache License v2.0.

On AVX512 it provides an up to 8x improvement (over 3 GB/s per core) in comparison to AVX2. SHA Extensions give a performance boost of close to 4x over AVX2. + +## Introduction + +This package is designed as a replacement for `crypto/sha256`. For Intel CPUs it has two flavors for AVX512 and AVX2 (AVX/SSE are also supported). For ARM CPUs with the Cryptography Extensions, advantage is taken of the SHA2 instructions resulting in a massive performance improvement. + +This package uses Golang assembly. The AVX512 version is based on the Intel's "multi-buffer crypto library for IPSec" whereas the other Intel implementations are described in "Fast SHA-256 Implementations on Intel Architecture Processors" by J. Guilford et al. + +## New: Support for Intel SHA Extensions + +Support for the Intel SHA Extensions has been added by Kristofer Peterson (@svenski123), originally developed for spacemeshos [here](https://github.com/spacemeshos/POET/issues/23). On CPUs that support it (known thus far Intel Celeron J3455 and AMD Ryzen) it gives a significant boost in performance (with thanks to @AudriusButkevicius for reporting the results; full results [here](https://github.com/minio/sha256-simd/pull/37#issuecomment-451607827)). + +``` +$ benchcmp avx2.txt sha-ext.txt +benchmark AVX2 MB/s SHA Ext MB/s speedup +BenchmarkHash5M 514.40 1975.17 3.84x +``` + +Thanks to Kristofer Peterson, we also added additional performance changes such as optimized padding, endian conversions which sped up all implementations i.e. Intel SHA alone while doubled performance for small sizes, the other changes increased everything roughly 50%. + +## Support for AVX512 + +We have added support for AVX512 which results in an up to 8x performance improvement over AVX2 (3.0 GHz Xeon Platinum 8124M CPU): + +``` +$ benchcmp avx2.txt avx512.txt +benchmark AVX2 MB/s AVX512 MB/s speedup +BenchmarkHash5M 448.62 3498.20 7.80x +``` + +The original code was developed by Intel as part of the [multi-buffer crypto library](https://github.com/intel/intel-ipsec-mb) for IPSec or more specifically this [AVX512](https://github.com/intel/intel-ipsec-mb/blob/master/avx512/sha256_x16_avx512.asm) implementation. The key idea behind it is to process a total of 16 checksums in parallel by “transposing” 16 (independent) messages of 64 bytes between a total of 16 ZMM registers (each 64 bytes wide). + +Transposing the input messages means that in order to take full advantage of the speedup you need to have a (server) workload where multiple threads are doing SHA256 calculations in parallel. Unfortunately for this algorithm it is not possible for two message blocks processed in parallel to be dependent on one another — because then the (interim) result of the first part of the message has to be an input into the processing of the second part of the message. + +Whereas the original Intel C implementation requires some sort of explicit scheduling of messages to be processed in parallel, for Golang it makes sense to take advantage of channels in order to group messages together and use channels as well for sending back the results (thereby effectively decoupling the calculations). We have implemented a fairly simple scheduling mechanism that seems to work well in practice. + +Due to this different way of scheduling, we decided to use an explicit method to instantiate the AVX512 version. Essentially one or more AVX512 processing servers ([`Avx512Server`](https://github.com/minio/sha256-simd/blob/master/sha256blockAvx512_amd64.go#L294)) have to be created whereby each server can hash over 3 GB/s on a single core. An `hash.Hash` object ([`Avx512Digest`](https://github.com/minio/sha256-simd/blob/master/sha256blockAvx512_amd64.go#L45)) is then instantiated using one of these servers and used in the regular fashion: + +```go +import "github.com/minio/sha256-simd" + +func main() { + server := sha256.NewAvx512Server() + h512 := sha256.NewAvx512(server) + h512.Write(fileBlock) + digest := h512.Sum([]byte{}) +} +``` + +Note that, because of the scheduling overhead, for small messages (< 1 MB) you will be better off using the regular SHA256 hashing (but those are typically not performance critical anyway). Some other tips to get the best performance: +* Have many go routines doing SHA256 calculations in parallel. +* Try to Write() messages in multiples of 64 bytes. +* Try to keep the overall length of messages to a roughly similar size ie. 5 MB (this way all 16 ‘lanes’ in the AVX512 computations are contributing as much as possible). + +More detailed information can be found in this [blog](https://blog.minio.io/accelerate-sha256-up-to-8x-over-3-gb-s-per-core-with-avx512-a0b1d64f78f) post including scaling across cores. + +## Drop-In Replacement + +The following code snippet shows how you can use `github.com/minio/sha256-simd`. This will automatically select the fastest method for the architecture on which it will be executed. + +```go +import "github.com/minio/sha256-simd" + +func main() { + ... + shaWriter := sha256.New() + io.Copy(shaWriter, file) + ... +} +``` + +## Performance + +Below is the speed in MB/s for a single core (ranked fast to slow) for blocks larger than 1 MB. + +| Processor | SIMD | Speed (MB/s) | +| --------------------------------- | ------- | ------------:| +| 3.0 GHz Intel Xeon Platinum 8124M | AVX512 | 3498 | +| 3.7 GHz AMD Ryzen 7 2700X | SHA Ext | 1979 | +| 1.2 GHz ARM Cortex-A53 | ARM64 | 638 | +| 3.0 GHz Intel Xeon Platinum 8124M | AVX2 | 449 | +| 3.1 GHz Intel Core i7 | AVX | 362 | +| 3.1 GHz Intel Core i7 | SSE | 299 | + +## asm2plan9s + +In order to be able to work more easily with AVX512/AVX2 instructions, a separate tool was developed to convert SIMD instructions into the corresponding BYTE sequence as accepted by Go assembly.

For instance during multi part uploads each part that is uploaded needs to be verified for data integrity by the server. + +Other applications that can benefit from enhanced SHA256 performance are deduplication in storage systems, intrusion detection, version control systems, integrity checking, etc. + +## ARM SHA Extensions + +The 64-bit ARMv8 core has introduced new instructions for SHA1 and SHA2 acceleration as part of the [Cryptography Extensions](http://infocenter.arm.com/help/index.jsp?topic=/com.arm.doc.ddi0501f/CHDFJBCJ.html).
