Sonia's research focuses on the combined exploration of the optimization space for convolutional algorithms and the design space of tightly coupled architectures, with the goal of providing insights for designing future CPUs optimized for CNN inference. So far, she has investigated optimizations for the im2col+GEMM, Winograd, and Direct algorithms, along with tuning of micro-architectural parameters such as vector lengths, L2 cache, and on-chip parallelism on long vector architectures (RISC-VV, ARM-SVE). Now her interest is leading towards exploring dense transformers on multi-core architectures.

Hari's research focuses on performance characterization of the SYCL and OpenMP programming models, with an emphasis on SYCL through detailed micro-benchmarking.
