Jayneel Gandhi

I am a Senior Researcher at VMware Research. My research interests are in specialized hardware accelerators, emerging memory/storage technologies, hardware-software co-design, operating systems, virtualization and distributed systems.

Curriculum Vitae

Research Projects

My research securely virtualizes and eases the adoption of heterogeneous accelerators and emerging memory technologies by introducing useful operating system abstractions and efficient memory system architectures.

Mitosis	Creating mechanisms and policies for explicit page-table placement in NUMA machines
Project PBerry	Using cache-coherent FPGAs to offload memory management tasks in various use cases
Remote Memory	Exploring the ability of a host to access the memory of another host without involving the remote processor
Concurrent GPUs	Enabling multi-application concurrency on GPUs for efficient workload consolidation in the cloud
Non-Volatile Memories	Designing abstraction for both crash-consistency and synchronization with persistent memories
Memory Virtualization	Innovating alternative fast address translation mechanisms without significantly losing the benefits of paging
FabScalar Project	Composing Synthesizable RTL Designs of Arbitrary Cores within a Canonical Superscalar Template
