# Parity-Checked Strassen Algorithm

@article{Wang2020ParityCheckedSA, title={Parity-Checked Strassen Algorithm}, author={Hsin-Po Wang and Iwan M. Duursma}, journal={ArXiv}, year={2020}, volume={abs/2011.15082} }

To multiply astronomic matrices using parallel workers subject to straggling, we recommend interleaving checksums with some fast matrix multiplication algorithms. Nesting the parity-checked algorithms, we weave a product code flavor protection. Two demonstrative configurations are as follows: (A) $9$ workers multiply two $2\times 2$ matrices; each worker multiplies two linear combinations of entries therein. Then the entry products sent from any $8$ workers suffice to assemble the matrix…

This paper is a refinement of the laser method that improves the resulting value bound for most sufficiently large tensors, and obtains the best bound on $\omega$ to date.

Block-Diagonal and LT Codes for Distributed Computing With Straggling Servers

- Computer ScienceIEEE Transactions on Communications
- 2019

Two coded schemes for the distributed computing problem of multiplying a matrix by a set of vectors are proposed and it is shown numerically that the proposed schemes outperform other schemes in the literature, with the LT code-based scheme yielding the best performance for the scenarios considered.

Rateless Codes for Near-Perfect Load Balancing in Distributed Matrix-Vector Multiplication

This paper proposes a rateless fountain coding strategy that achieves the best of both worlds -- it is proved that its latency is asymptotically equal to ideal load balancing, and it performs asymPTotically zero redundant computations.

Straggler Resilient Serverless Computing Based on Polar Codes

- Computer Science2019 57th Annual Allerton Conference on Communication, Control, and Computing (Allerton)
- 2019

This work designs a sequential decoder specifically for polar codes in erasure channels with full-precision input and outputs and introduces the idea of partial polarization which reduces the computational burden of encoding and decoding at the expense of straggler-resilience.

“Short-Dot”: Computing Large Linear Transforms Distributedly Using Coded Short Dot Products

- Computer ScienceIEEE Transactions on Information Theory
- 2019

The key novelty in this work is that in the particular regime where the number of available processing nodes is greater than the total number of dot products, Short-Dot has lower expected computation time under straggling under an exponential model compared to existing strategies.

Coded Sparse Matrix Multiplication

- Computer ScienceICML

A new coded computation strategy, calledparse code, is developed, which achieves near the optimal recovery threshold, low computation overhead, and linear decoding time, and is implemented and demonstrated over both uncoded and current fastest coded strategies.
