Deron Eriksson commented on SYSTEMML-1223:
------------------------------------------
cc [~mboehm7]
Is block size information (rows_in_block, cols_in_block) written into the
binary matrix file itself, or do the rows_in_block and cols_in_block values
just need to be written to the metadata file?
> 'write` Statements Ignore `rows_in_block`, `cols_in_block` Arguments

> Reporter: Mike Dusenberry
>
> Given a DML script that writes matrices in binary form to disk, the
> {{rows_in_block}} and {{cols_in_block}} arguments will be ignored, and the
> default of 1000 will be used.
> {code}
> write(X, "X", format="binary", rows_in_block=batchSize, cols_in_block=cols)
> {code}
