@hackage lvish1.0.0.6

Parallel scheduler, LVar data structures, and infrastructure to build more.

debug

(off by default)

Activate additional debug assertions, and printed output if DEBUGLVL env var is set to 1 or higher.

chaselev

(on by default)

Use the Chase-Lev work-stealing deque

getonce

(off by default)

Ensure that continuations of get run at most once (by using extra synchronization)

A programming model based on monotonically-growing concurrent data structures.

As a starting point, look at Control.LVish, as well as one of these papers:

FHPC 2013: LVars: lattice-based data structures for deterministic parallelism (http://dl.acm.org/citation.cfm?id=2502326).
POPL 2014: Freeze after writing: quasi-deterministic parallel programming with LVars (http://www.cs.indiana.edu/~lkuper/papers/2013-lvish-draft.pdf).
