### π The feature, motivation and pitch
It would be great to have a general parallel prefix sum (associative scan) operation in PyTorch, something like [associative_scan](https://jax.readthedocs.ioβ¦

Earlier work (~2017 for 42ITy) saw addition of pthreads support for networked scans, so that large subnets could be scanned in finite time. IIRC, this used separate thread pools per "bus", so scans inβ¦

Hello,
I am running parallelScanAsStream to dump a whole DynamoDB table to S3. It is awfully slow though, slower than running sequential scan. Running it locally I am getting results like:

## Summary
Would be nice if Hermes would scan chains in parallel on startup.
## Problem Definition
On startup, Hermes scans chains for open channels, and apparently it's done sequenβ¦

### Current Behavior
From my testing Artifact transforms for external modules are exectued in parallel. Artifact transforms for project dependencies are executed sequential. This can cause severe pβ¦
