These changes involve adding temporal data to arrays or queues during intermediary operations. To enhance efficiency and minimize memory usage, we integrated dynamic programming. Experimental results demonstrate the improved scalability and effectiveness of the proposed approach in terms of memory usage.},

abstract = {Gradient sparsification is a widely adopted solution for reducing

the excessive communication traffic in distributed deep learning.

However, most existing gradient sparsifiers have relatively poor

scalability because of considerable computational cost of gradient

selection and/or increased communication traffic owing to gradient

build-up. To address these challenges, we propose a novel gradient

sparsification scheme, DEFT, that partitions the gradient selection

task into sub tasks and distributes them to workers. DEFT differs

from existing sparsifiers, wherein every worker selects gradients

among all gradients. Consequently, the computational cost can

be reduced as the number of workers increases. Moreover, gradient build-up can be eliminated because DEFT allows workers to

select gradients in partitions that are non-intersecting (between

workers). Therefore, even if the number of workers increases, the

communication traffic can be maintained as per user requirement.

To avoid the loss of significance of gradient selection, DEFT

selects more gradients in the layers that have a larger gradient

norm than the other layers. Because every layer has a different

computational load, DEFT allocates layers to workers using a binpacking algorithm to maintain a balanced load of gradient selection

between workers. In our empirical evaluation, DEFT shows a significant improvement in training performance in terms of speed

in gradient selection over existing sparsifiers while achieving high

convergence performance.},
