FliX: Flipped-Indexing for Scalable GPU Queries and Updates
Rosina Kharal, Trevor Brown, Justus Henneberg +1
GPU-based concurrent data structures (CDSs) achieve high throughput for read-only queries, but efficient support for dynamic updates on fully GPU-resident data remains challenging.…

More Bang For Your Buck(et): Fast and Space-efficient Hardware-accelerated Coarse-granular Indexing on GPUs
Justus Henneberg, Felix Schuhknecht, Rosina Kharal +1
In recent work, we have shown that NVIDIA's raytracing cores on RTX video cards can be exploited to realize hardware-accelerated lookups for GPU-resident database indexes. On a hig…

Performance Anomalies in Concurrent Data Structure Microbenchmarks
Rosina F. Kharal, Trevor Brown
Recent decades have witnessed a surge in the development of concurrent data structures with an increasing interest in data structures implementing concurrent sets (CSets). Microben…
