When migrating worker-side data in LDA app, we have a problem that model is damaged during migration. It's because some of our apps have also partial models in the input...
Currently we have a simple version of scheduler (`FIFOScheduler`) by #1216. We need to introduce a new sophisticated scheduler for specific goals: - handling opportunistic resources - handling workload dynamics...
I've met an 'out of memory: unable to create new native thread' error, while running an NMF app in optiplex cluster. It happens while starting model evaluation. I've met it...
