ReneEnjilian opened a new pull request, #2040: URL: https://github.com/apache/systemds/pull/2040
This pull request implements the Modified Compressed Sparse Column (MCSC) block. So far, most sparse blocks in SystemDS were row oriented (MCSR, CSR, DCSR). MCSC follows a similar design as MCSR but storing individual columns instead of rows. For simplicity, we reused the existing SparseRowVector/SparseRowScalar classes for the columns. The main contribution is in SparseBlockMCSC.java, where the entire structure is implemented. Further, testing has been added. Subsequent tasks may require a deeper integration into the system. Specifically, a deeper integration is required regarding alignment, iterators and merging with other matrices. -- This is an automated message from the Apache Git Service.
