Option to disable pre-allocation #66

Closed onlyjob closed 4 years ago

onlyjob commented 4 years ago

Please consider adding an option to disable pre-allocation. Some distributed network file systems have no concept of continuous unfragmented file and pre-allocation only slows down the progress by writing the file twice...

Thanks.

The optimisation process of PoC2 requires pre-allocation. If your distributed network file system doesnt support fast preallocation, skipping it wouldn't help. The plot file is not written sequentially.
