A Pennsylvania start-up is using GPUs in the Amazon cloud to identify flaws, taints and contaminations to assist brewers with quality control. 24-year-old entrepreneur Jason Cohen and his 11-employee team, is using his companyʼs Gastrograph software that can now identify dozens of obscure beer styles — Vienna lagers, Irish dry stouts or Berliner Weissbiers — in seconds, rather than minutes.
Without the parallel architecture of GPUs, for example, it took Cohen’s team a long time to train deep neural networks with many layers, or random forest models with many trees. Cohen’s team now uses NVIDIA’s CUDA toolkit in R — such as gputools and gmatrix — to boost performance. Now model tuning only takes minutes to complete.
