Baunsgaard opened a new pull request #1173: URL: https://github.com/apache/systemds/pull/1173
This PR contains an addition to slice compressed, that allows the slices not to decompress the entire matrix, but only the sliced parts. The implementation handle the following cases: - single value slice, is replaced by a getValue() that is placed into a new matrix output. - Row slices, that only decompress the rows selected - Column slices, that maintain compressed outputs. - Selective row/col slices that leverage first the column slice followed by a decompressing row slice. A further improvement would be to maintain compression if the Row slice is large enough to do so. But this would require further work. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
