PROFILE

Karthick Panner Selvam

Worked on enhancing developer experience and debugging efficiency in the graphcore/pytorch-fork repository by improving error reporting for size, stride, and alignment checks. Leveraged C++ and Python to include operator names in assertion messages, providing immediate context for failures in the Inductor and Dynamo pipelines. Added comprehensive unit tests to ensure error messages preserved operator context, supporting both passing and failing scenarios. Later, contributed to pytorch-labs/tritonbench by implementing backward mode support for the softmax operator using PyTorch and Triton, refactoring the operator to use torch.autograd.Function and a dedicated backward kernel to enable gradient computation in benchmarking workflows.

May 2025 monthly summary for graphcore/pytorch-fork. Focused on improving developer debugging and stability by enhancing error reporting for size/stride/alignment checks. The enhancement adds the operator name to assertion errors, providing immediate context for failures in the Inductor/Dynamo pipeline. This enables faster triage and reduces debugging time for shape/stride/alignment issues in CI and experiments.
