⚡ Kernels & Compilers🔒 Premium

CUDA Compilation: PTX, Cubins and SASSCUDA source, PTX and native GPU instructions describe different stages of execution. Inspect the selected binary and its resource use before explaining a performance change.

⚡ Kernels & Compilers🔒 Premium

Tiled Matrix MultiplicationTiled matrix multiplication reuses input values across many output calculations. Shared-memory and register tiles reduce repeated data movement while consuming limited on-chip resources.

⚡ Kernels & Compilers

CUDA Programming ModelCUDA programs launch GPU kernels from host code. Thread indexing, memory access and stream ordering determine whether the result is correct.

🧮 Open Weights & Serving Engines

Serving Benchmarks That Do Not LieDesign reproducible serving experiments with realistic arrivals, cache state and failure accounting. Interpret latency-qualified throughput and conditional per-rank bounds without turning optimistic kernel estimates into production capacity.
