Overview

thinc-apple-ops

Make spaCy and Thinc up to 8 × faster on macOS by calling into Apple's native libraries.

⏳ Install

Make sure you have Xcode installed and then install with pip:

pip install thinc-apple-ops

🏫 Motivation

Matrix multiplication is one of the primary operations in machine learning. Since matrix multiplication is computationally expensive, using a fast matrix multiplication implementation can speed up training and prediction significantly.

Most linear algebra libraries provide matrix multiplication in the form of the standardized BLAS gemm functions. The work behind scences is done by a set of matrix multiplication kernels that are meticulously tuned for specific architectures. Matrix multiplication kernels use architecture-specific SIMD instructions for data-level parallism and can take factors such as cache sizes and intstruction latency into account. Thinc uses the BLIS linear algebra library, which provides optimized matrix multiplication kernels for most x86_64 and some ARM CPUs.

Recent Apple Silicon CPUs, such as the M-series used in Macs, differ from traditional x86_64 and ARM CPUs in that they have a separate matrix co-processor(s) called AMX. Since AMX is not well-documented, it is unclear how many AMX units Apple M CPUs have. It is certain that the (single) performance cluster of the M1 has an AMX unit and there is empirical evidence that both performance clusters of the M1 Pro/Max have an AMX unit.

Even though AMX units use a set of undocumented instructions, the units can be used through Apple's Accelerate linear algebra library. Since Accelerate implements the BLAS interface, it can be used as a replacement of the BLIS library that is used by Thinc. This is where the thinc-apple-ops package comes in. thinc-apple-ops extends the default Thinc ops, so that gemm matrix multiplication from Accelerate is used in place of the BLIS implementation of gemm. As a result, matrix multiplication in Thinc is performed on the fast AMX unit(s).

⏱ Benchmarks

Using thinc-apple-ops leads to large speedups in prediction and training on Apple Silicon Macs, as shown by the benchmarks below.

Prediction

This first benchark compares prediction speed of the de_core_news_lg spaCy model between the M1 with and without thinc-apple-ops. Results for an Intel Mac Mini and AMD Ryzen 5900X are also provided for comparison. Results are in words per second. In this prediction benchmark, using thinc-apple-ops improves performance by 4.3 times.

MacBook Air Core i5 2020 9790 10983 9
AMD Ryzen 5900X 22568 N/A 52

Training

In the second benchmark, we compare the training speed of the de_core_news_lg spaCy model (without NER). The results are in training iterations per second. Using thinc-apple-ops improves training time by 3.0 times.

  • Pass through Accelerate sgemm/saxpy in Ops.cblas

    Pass through Accelerate sgemm/saxpy in Ops.cblas

    This can be used by e.g. the parser in spaCy 3.4 to use Accelerate's implementations.

    I am not sure how to handle this dependency-wise, since this requires Thinc 8.1, but we still want to people to be able to use thinc-apple-ops with Thinc 8.0.x and spaCy < 3.4. Do we need another minor release that sets thinc < 8.1.0?

    Hi I tried to use this awesome package and I am getting this error. Not sure what it means, maybe you guys could help me?

    I should mention that my data is quite big and I am also using some SWAP space. Could this be the reason of this error?

    AppleOps.gemm: write in-place when `output` is given

    NumpyOps.gemm (with BLIS) writes the result of matrix multiplication in-place when the output argument is given. This changes AppleOps.gemm to do the same, avoiding allocation of a temporary.

    Change thinc upper bound to <8.1.0

    thinc-apple-ops will require thinc >= 8.1.0 in the future for the CBLAS passthrough functionality. As discussed in #15, we should first do another minor thinc-apple-ops release specifically for thinc <8.1.0.

    Also bump the version to v0.0.7 to prepare for the release.

  • Fix 0-size arrays

    Fix 0-size arrays

    Our bit of Cython code uses memory buffers, which apparently have a bounds-check when the size is 0 when acquiring the pointer. In contrast, in other bits of code we often acquire the buffer by casting the array.data pointer, which has no such bounds check. This led to IndexError being raised when zero shapes were passed through.

    Technically it doesn't require a currently unreleased version of thinc to run, but if people install it into an existing venv, then it's better to require the version of thinc to upgraded so that it's detected and used.
