A Locked Orthogonal Tree
David Charlton, Erik D. Demaine, Martin L. Demaine +2
We give a counterexample to a conjecture of Poon [Poo06] that any orthogonal tree in two dimensions can always be flattened by a continuous motion that preserves edge lengths and a…
An Architecture for Exploiting Native User-Land Checkpoint-Restart to Improve Fuzzing
Prashant Singh Chouhan, Gregory Price, Gene Cooperman
Fuzzing is one of the most popular and widely used techniques to find vulnerabilities in any application. Fuzzers are fast enough, but they still spend a good portion of time to re…
Spectroscopic signatures of next-nearest-neighbor hopping in the charge and spin dynamics of doped one-dimensional antiferromagnets
Umesh Kumar, Gregory Price, Kenneth Stiwinter +3
We study the impact of next-nearest-neighbor (nnn) hopping on the low-energy collective excitations of strongly correlated doped antiferromagnetic cuprate spin chains. Specifically…
MANA for MPI: MPI-Agnostic Network-Agnostic Transparent Checkpointing
Rohan Garg, Gregory Price, Gene Cooperman
Transparently checkpointing MPI for fault tolerance and load balancing is a long-standing problem in HPC. The problem has been complicated by the need to provide checkpoint-restart…
Security impact ratings considered harmful
Jeff Arnold, Tim Abbott, Waseem Daher +4
In this paper, we question the common practice of assigning security impact ratings to OS updates. Specifically, we present evidence that ranking updates by their perceived securit…
Equilibria: Fair Multi-Tenant CXL Memory Tiering At Scale
Kaiyang Zhao, Neha Gholkar, Hasan Maruf +7
Memory dominates datacenter system cost and power. Memory expansion via Compute Express Link (CXL) is an effective way to provide additional memory at lower cost and power, but its…
