Sparkle: Optimizing Spark for Large Memory Machines and Analytics
Mijung Kim, Jun Li, Haris Volos +7
Spark is an in-memory analytics platform that targets commodity server environments today. It relies on the Hadoop Distributed File System (HDFS) to persist intermediate checkpoint…
Oxygen migration during resistance switching and failure of hafnium oxide memristors
Suhas Kumar, Ziwen Wang, Xiaopeng Huang +7
While the recent establishment of the role of thermophoresis/diffusion-driven oxygen migration during resistance switching in metal oxide memristors provided critical insights requ…
The Many Faces of Data-centric Workflow Optimization: A Survey
Georgia Kougka, Anastasios Gounaris, Alkis Simitsis
Workflow technology is rapidly evolving and, rather than being limited to modeling the control flow in business processes, is becoming a key mechanism to perform advanced data mana…
Spatially uniform resistance switching of low current, high endurance titanium-niobium-oxide memristors
Suhas Kumar, Noraica Davila, Ziwen Wang +6
We analyzed micrometer-scale titanium-niobium-oxide prototype memristors, which exhibited low write-power (<3 μW) and energy (<200 fJ/bit/μm2), low read-power (~nW), and high endur…
Conduction Channel Formation and Dissolution Due to Oxygen Thermophoresis/Diffusion in Hafnium Oxide Memristors
Suhas Kumar, Ziwen Wang, Xiaopeng Huang +7
Transition metal oxide memristors, or resistive random-access memory (RRAM) switches, are under intense development for storage-class memory because of their favorable operating po…
