NVMe SSDs based on flash are cheap and offer high throughput. Combining several of
these devices into a single server enables 10 million I/O operations per second or more. Our …

Log-based data management systems use storage as if it were an append-only medium,
transforming random writes into sequential writes, which delivers significant benefits when …

The recent exciting development of persistent memory (PM) has led to many new proposals
that directly operate and persist indexes on the memory bus, potentially removing the need …

The end of Moore's law has sparked a surge on programmable accelerators (eg, SmartNICs,
TPUs) for continued scaling of application performance. However, despite the great success …

Analytical engines rely on in-memory caching to avoid disk accesses and provide timely
responses by keeping the most frequently accessed data in memory. Purely frequency-& …

The idea of pushing computation to storage devices has been explored for decades, without
widespread adoption so far. The definition of Computational Programs namespaces in …

One of the main challenges for modern processors is the data transfer between processor
and memory. Such data movement implies high latency and high energy consumption. In …

The conventional database buffer managers have two inherent sources of I/O serialization:
read stall and mutex conflict. The serialized I/O makes storage and CPU under-utilized …

Programmable accelerators enable the execution of applications intended for running in
usual servers. However, inappropriately running applications on these devices can lead to …

High-density 3D NAND flash like QLC (Quad-Level Cell) is prevailing in providing large
capacities for data-intensive applications. Because of the structure limitation, a two-step …
