Lewis John McGibbney commented on JOSHUA-318:
---------------------------------------------
Agreed, it's set for fix 6.2... if we ever release 6.2.
> scripts/training/run_tuner.py should enable configurable memory usage when
> invioking joshua-decoder

> This is because, by default the joshua-decoder script runs with 4g of memory.
> The run_runer.py script should be flexible enough to continue with the memory
> allocation provided when a pipe was initially invoked. This value should then
> be passed to the joshua-decoder script.
