### What changes were proposed in this pull request? Following https://github.com/apache/spark/pull/30810, I've continued looking for ways to accelerate the usage of BLAS in Spark. With this PR, I integrate work done in the [`dev.ludovic.netlib`](https://github.com/luhenry/netlib/) Maven package. The `dev.ludovic.netlib` library wraps the original `com.github.fommil.netlib` library and focus on accelerating the linear algebra routines in use in Spark. When running the `org.apache.spark.ml.linalg.BLASBenchmark` benchmarking suite, I get the results at [1] on an Intel machine. Moreover, this library is thoroughly tested to return the exact same results as the reference implementation. Under the hood, it reimplements the necessary algorithms in pure autovectorization-friendly Java 8, as well as takes advantage of the Vector API and Foreign Linker API introduced in JDK 16 when available. A table summarising which version gets loaded in which case: ``` | | BLAS.nativeBLAS | BLAS.javaBLAS | | --------------------- | -------------------------------------------------- | -------------------------------------------------- | | with -Pnetlib-lgpl | 1. dev.ludovic.netlib.blas.NetlibNativeBLAS, a | 1. dev.ludovic.netlib.blas.VectorizedBLAS | | | wrapper for com.github.fommil:all | (JDK16+, relies on the Vector API, requires | | | 2. dev.ludovic.netlib.blas.ForeignBLAS (JDK16+, | `--add-modules=jdk.incubator.vector` on JDK16) | | | relies on the Foreign Linker API, requires | 2. dev.ludovic.netlib.blas.Java11BLAS (JDK11+) | | | `--add-modules=jdk.incubator.foreign | 3. dev.ludovic.netlib.blas.JavaBLAS | | | -Dforeign.restricted=warn`) | 4. dev.ludovic.netlib.blas.NetlibF2jBLAS, a | | | 3. fails to load, falls back to BLAS.javaBLAS in | wrapper for com.github.fommil:core | | | org.apache.spark.ml.linalg.BLAS | | | --------------------- | -------------------------------------------------- | -------------------------------------------------- | | without -Pnetlib-lgpl | 1. dev.ludovic.netlib.blas.ForeignBLAS (JDK16+, | 1. dev.ludovic.netlib.blas.VectorizedBLAS | | | relies on the Foreign Linker API, requires | (JDK16+, relies on the Vector API, requires | | | `--add-modules=jdk.incubator.foreign | `--add-modules=jdk.incubator.vector` on JDK16) | | | -Dforeign.restricted=warn`) | 2. dev.ludovic.netlib.blas.Java11BLAS (JDK11+) | | | 2. fails to load, falls back to BLAS.javaBLAS in | 3. dev.ludovic.netlib.blas.JavaBLAS | | | org.apache.spark.ml.linalg.BLAS | 4. dev.ludovic.netlib.blas.NetlibF2jBLAS, a | | | | wrapper for com.github.fommil:core | | --------------------- | -------------------------------------------------- | -------------------------------------------------- | ``` ### Why are the changes needed? Accelerates linear algebra operations when the pure-java fallback method is in use. Transparently falls back to native implementation (OpenBLAS, MKL) when available. ### Does this PR introduce _any_ user-facing change? No, all changes are transparent to the user. ### How was this patch tested? The `dev.ludovic.netlib` library has its own test suite [2]. It has also been validated by running the Spark test suite and benchmarking suite.
