hyperion's Introduction

About

Hyperion is a Haskell framework for running concurrent computations on an HPC cluster [1] [2], based on the distributed-process library. It is targeted at clusters running the Slurm workload manager. However, it can in principle be modified to use an arbitrary resource manager.

See the example directory for usage examples. The example example/src-root-search/Main.hs demonstrates most of the main features.

[1]: The design of Hyperion was heavily inspired by Haxl, although unlike Haxl, we choose not to break the standard relationship between ap and <*>.

[2]: Hyperion is named after the (now defunct) Hyperion cluster at the IAS.

hyperion's Issues

Treat ErrorBusy in SQLite differently

Right now all SQLError are treated the same way and we retry a configured number of times. Maybe it makes sense to inspect SQLError and on sqlError = ErrorBusy just retry indefinitely (or use timeout) and maybe more often without writing warnings to the log?

I guess I have no idea how often this error arises but given that dbRetries is configurable, it seems that it is often enough, and sometimes a lot of retries is required.
