Krish Gupta
Passionate about parallel computing, optimizing hardware, and building efficient AI infrastructure.
- LLVM/Flang OpenMP: Merged PRs for semantics, diagnostics, and regression test coverage.
- GSoC 2025 GNU Radio: Ported critical block families to 4.0 with ~2x throughput gains.
- Performance Tooling: Built Roofline analysis and Slurm cluster ops tools.
- Product & Entrepreneurship: Previously built multiple successful ventures; passionate about shipping user-centric products.
Selected Engineering
GPU Roofline Benchmark
A cross-platform benchmarking tool to identify bandwidth vs. compute bottlenecks across diverse hardware (CPU, CUDA, Metal).
- Built micro-benchmarks (SAXPY/Triad/SGEMM) for peak performance measurement.
- Automated device selection and roofline plotting logic.
- Supports heterogeneous backends (CUDA, Metal, OpenMP).
Slurm Mini-Cluster
Local simulation of a multi-node HPC cluster for job scheduling and parallel workload validation.
- Deployed multi-node Ubuntu cluster with Slurm + Munge authentication.
- Validated scheduling policies with real MPI/OpenMP workloads.
- Created comprehensive ops runbook for job triage and service recovery.
GNU Radio 4.0 Expansion GSoC '25
Ported and modernized legacy DSP blocks to the new modular 4.0 architecture, enabling high-throughput signal chains.
- Implemented Math/Analog/Digital families using C++23 template-registry patterns.
- Achieved ~2x throughput in targeted benchmarks vs legacy blocks.
- Added 75+ GoogleTest units and established CI regression baselines.
Building
Safety middleware for autonomous agents. Enforces deterministic output constraints and behavioral bounds for LLM-driven actions.
ReliabilityRequest coalescing backend. Implements Redis-based locking to reduce redundant upstream LLM calls and improve tail latency.
PerformanceOpen Source
Contributing to the Flang frontend for OpenMP support. Focused on semantics correctness and diagnostics.
- Fixed atomic ops on complex types.
- Added FileCheck regression coverage.
Core contributor to the next-gen SDR runtime (GSoC '25).
- Migrated 4000+ LOC to C++23.
- Optimized memory handling for block buffers.
