Subject [jira] [Created] (SINGA-148) Race condition between Worker threads and Driver

             Summary: Race condition between Worker threads and Driver
                 Key: SINGA-148
                 URL: https://issues.apache.org/jira/browse/SINGA-148
             Project: Singa
          Issue Type: Bug
         Environment: Tested on Debian 8.3
            Reporter: Tan Li Boon


In the main branch, a thread of execution for each worker is started before information about
its device type is passed into it.

This causes test cases such as MNIST to not use GPUs for calculation, and other test cases
such as CIFAR10 to fail when it attempts to perform cudnn-based functions on the CPU.

A temporary workaround is to make the worker thread sleep for 1 second, but that's not a desirable
workaround.

This issue aims to implement a proper fix.
