PROFILE
Kalyan Kumar
Kalyan Kumar contributed to the huggingface/optimum-habana repository by engineering features and fixes that improved large Llama model deployment on Habana hardware. He optimized memory usage and stability by refining memory management during inference, aligning execution with hardware limits, and introducing BF16 logits computation to reduce memory footprint. Kalyan also addressed cross-attention mask alignment for correct masking and fewer retraces, and implemented batch splitting in attention and MLP layers to mitigate NIC latency and enhance throughput. His work, primarily in Python and PyTorch, demonstrated depth in deep learning, distributed systems, and model optimization, resulting in more reliable and efficient large-model inference.

Feb 1, 2025February 2025: Delivered a performance-focused feature for the Llama model on Habana hardware in the huggingface/optimum-habana repository. Implemented batch splitting for attention and MLP to hide NIC latency, adding a new runtime argument --attn_batch_split to control the behavior. The feature is designed to be enabled for prompt processing under defined conditions to optimize throughput while preserving correctness across layers and during prompt generation. This work improves inference efficiency on Habana accelerators and lays groundwork for further latency-hiding optimizations.
