Summary: Performance issue codegen outer over ultra-sparse matrices
Key: SYSTEMML-1841
URL: https://issues.apache.org/jira/browse/SYSTEMML-1841
Project: SystemML
Issue Type: Bug
Reporter: Matthias Boehm
Experiments with codegen outer operations over the Amazon Books review dataset
(8,026,324 x 2,330,066, nnz=22,507,155, i.e., sparsity=10^(-6)) showed
unnecessary overhead for this ultra-sparse data set. This task aims to remove
this overhead.
