R&D Thesis: Optimizing HTAP workloads using Matrix Multiplication

R&D Thesis: Optimizing HTAP workloads using Matrix Multiplication 621549BR Your Role and Responsibilities SAP HANA on IBM Power technology is used in business-critical solutions. Our development team working on the SAP campus in St. Leon Rot ensures that these solutions are running optimal on IBM Power architecture.We are looking for a student who has interest in doing some research on a topic combining hardware accelerators and database technology. Background and topic of the master thesis:In 2022, Zichun Huang and Shimin Chen made a proposal to use matrix multiplication for implementing a Join-Project database operator. To put it in a nutshell, the idea is to describe distinct values in a table as nodes in a graph. Relations in a table are described as Edge. Such tuples can be written as adjacence matrices. A Join-Project operation between two tables is then equivalent to the multiplication of each table's adjacence matrix.For a business application, several pieces of information are yet missing: (1) The paper evaluates their approach with graph datasets, not with OLAP datasets. They explicitly outrule TPC-H as usable dataset for their use case. The relevance for relational databases is therefore unclear. (2) Even though, each relation is stored as one bit, matrices may become very large. What is the `cost` to keep and maintain such matrices? (3) Currently, P10 MMA supports down to 4-bit integers, only. What matrix layout is reasonable if we interpreted the 16-Byte input as 1-bit integer type? (4) The original papers only evaluate their approach in isolated environments. How do we maintain such matrices in real databases with isolation levels and concurrent OLTP?If you are interested to work in a dynamic and international team apply instantly.
