>
> This epic aims to add support for large-dense matrix blocks. Due to
> linearized double arrays and Java's limitation of 2G array elements, the
> current dense block representation is limited to 16GB. Given the trends
> towards large memory and scale-up environments, there is a needs to overcome
> this limitation. In order to avoid the memory inefficiency of two-dimensional
> (nested) arrays or chunked storage, we aim to provide alternative
> implementations that are selected based on the dimensions of allocated matrix
> blocks.
