HetCache: Synergising NVMe Storage and GPU acceleration for Memory-Efficient Analytics
Anastasia Ailamaki, Periklis Chrysogelos, Hamish Mcniece Hill Nicholson, Syed Mohammad Aunn Raza
Accessing input data is a critical operation in data analytics: i) slow data access significantly degrades performance, and ii) storing everything in the fastest medium, i.e., memory, incurs high operational and hardware costs. Further, while GPUs offer in ...
2023Interleaving with coroutines: a systematic and practical approach to hide memory latency in index joins
Anastasia Ailamaki, Georgios Psaropoulos
Index joins present a case of pointer-chasing code that causes data cache misses. In principle, we can hide these cache misses by overlapping them with computation: The lookups involved in an index join are parallel tasks whose execution can be interleaved ...
2018Micro-architectural Analysis of In-memory OLTP
Anastasia Ailamaki, Pinar Tözün, Danica Porobic, Utku Sirin
Micro-architectural behavior of traditional disk-based online transaction processing (OLTP) systems has been investigated extensively over the past couple of decades. Results show that traditional OLTP mostly under-utilize the available micro-architectural ...
