Serverless WebAssembly for compute-intensive workloads

on YouTube ↗16m

" summary

Serverless WebAssembly runs a compiled C simulator to generate FASTQ-style reads on demand: wg sim compiled from C to Wasm deployed to Cloudflare Workers with 128 MB RAM. The implementation streams reference slices from S3, mutates them into simulated reads, and streams results back so outputs can exceed memory limits. Demo endpoint wg sim.sandbox.bio returns randomized reads quickly with near-zero cold starts; Workers impose a ~30 second CPU and 128 MB memory limit.
