SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill requires sparq-gpu, and includes scripts (resource) components.

What problem does it solve?

This Skill evaluates the performance of GPU-based operations against CPU-based operations for sparq's hot-path operations, helping to determine whether GPU acceleration is beneficial.

Core Features & Use Cases

  • Performance Measurement: Compare the performance of GPU and CPU for various operations like FILTER + count, hash-join probe, and GROUP BY COUNT+SUM.
  • Opt-in Measurement Prototype: An opt-in prototype for evaluating GPU performance.
  • Use Case: Use this Skill to measure whether a GPU outperforms a CPU for sparq's columnar primitives, considering the cost of data transfer between host and device.

Quick Start

To get started with the gpu-kernels skill, execute the following command: cargo run --release -p sparq-gpu -- query data.ttl turtle 'SELECT ?s ?o WHERE { ?s http://schema.org/name ?o } LIMIT 10'

FAQPage Schema
How do I benchmark GPU versus CPU performance for columnar query operations?▼

To benchmark GPU versus CPU performance for columnar query operations, this Skill executes wgpu and WGSL compute kernels to measure hot-path primitives like FILTER, hash-join probe, and GROUP BY COUNT+SUM operations.

Does data transfer overhead negate GPU acceleration benefits for compute kernels?▼

Data transfer overhead between host and device is a critical factor. This Skill evaluates GPU acceleration benefits by explicitly weighing the compute speedup against the data transfer cost for columnar operations.

What do I need to run wgpu WGSL compute kernels for sparq performance measurement?▼

You need the sparq-gpu crate installed to execute the wgpu and WGSL compute kernels required for sparq performance measurement. You can run the prototype benchmarking scripts using the cargo release command.

Can I measure hash-join probe performance on the GPU using sparq?▼

Yes, you can measure hash-join probe performance on the GPU using sparq. The Skill evaluates specific hot-path operations including hash-join probes against CPU baselines to determine acceleration viability.

When should I not use GPU acceleration for sparq operations?▼

You should not use GPU acceleration for sparq operations when the benchmarking results indicate that data transfer overhead between host and device outweighs the compute performance gains of the GPU.
