pass cpplint check
> 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
> Labels: newbie
> Original Estimate: 1h
> Remaining Estimate: 1h
>
> 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.
