Access Trends of In-network Cache for Scientific Data

no code implementations11 May 2022 Ruize Han, Alex Sim, Kesheng Wu, Inder Monga, Chin Guok, Frank Würthwein, Diego Davila, Justas Balcas, Harvey Newman

Our study shows that this distributed storage cache is able to reduce the network traffic volume by a factor of 2. 35 during a part of the study period.

Adaptive Elastic Training for Sparse Deep Learning on Heterogeneous Multi-GPU Servers

1 code implementation13 Oct 2021 Yujing Ma, Florin Rusu, Kesheng Wu, Alexander Sim

We address these challenges with Adaptive SGD, an adaptive elastic model averaging stochastic gradient descent algorithm for heterogeneous multi-GPUs that is characterized by dynamic scheduling, adaptive batch size scaling, and normalized model merging.
