Description

Author: Colby Johnson

Date: 3March2014

Purpose: Check if parallelization on local machine is possible

Details:

  • Corpus: first_5hr/train
  • Nparts: 2
  • Queue type: Queue::POSIX
  • Density: 8
  • Senone: 5000

Results

  • Training was successful in: 35 min! half the time compared to identical setup using 1 part in exp 0168
  • Decode: xRT = 1.12
