[SYSTEMDS-2627] Federated mmchain instruction for lmCG, MLogreg, GLM This patch adds a federated mmchain instruction for a common matrix-vector multiplication chain as it appears in the inner loop of lmCG, Mlogreg, and GLM. It also includes a fix for more robust instruction manipulation, and a GLM federated test. Furthermore, we now use a slightly better approach for deciding between conf-only and context spark cluster analysis to avoid unnecessary spark context creation in local mode (which sometimes interferes with netty port allocation in federated tests).
Overview: SystemDS is a versatile system for the end-to-end data science lifecycle from data integration, cleaning, and feature engineering, over efficient, local and distributed ML model training, to deployment and serving. To this end, we aim to provide a stack of declarative languages with R-like syntax for (1) the different tasks of the data-science lifecycle, and (2) users with different expertise. These high-level scripts are compiled into hybrid execution plans of local, in-memory CPU and GPU operations, as well as distributed operations on Apache Spark. In contrast to existing systems - that either provide homogeneous tensors or 2D Datasets - and in order to serve the entire data science lifecycle, the underlying data model are DataTensors, i.e., tensors (multi-dimensional arrays) whose first dimension may have a heterogeneous and nested schema.

Status and Build: SystemDS is still in pre-alpha status. The original code base was forked from Apache SystemML 1.2 in September 2018. We will continue to support linear algebra programs over matrices, while replacing the underlying data model and compiler, as well as substantially extending the supported functionalities. Until the first release, you can build your own snapshot via Apache Maven: mvn clean package -P distribution
