Summary: Dense-sparse block conversions into memory-efficient CSR Key: SYSTEMML-2038 URL: https://issues.apache.org/jira/browse/SYSTEMML-2038 Project: SystemML Issue Type: Task Reporter: Matthias Boehm The sparse-dense matrix block conversion currently allocates the output in the default sparse representation, which is MCSR. However, this primitive knows the number of non-zeros upfront and hence can produce the output in CSR which is much more memory efficient. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
