wangwei closed SINGA-31.
------------------------
Resolution: Fixed
xpu is not needed. GPU is supported via SINGA-88.
> Extend Blob to support xpu (cpu or gpu)
> ---------------------------------------
>
> Key: SINGA-31
> URL: https://issues.apache.org/jira/browse/SINGA-31
> Project: Singa
> Issue Type: Bug
> Reporter: wangwei
>
> The Blob class is adapted from Caffe's code.
> It supports both GPU and CPU by providing classes like
> {code}
> gpu_data()；
> cpu_data()；
> {code}
> For GPU mode, users call gpu_data(); For CPU mode, users' code call cpu_data.
> Hence, users have to write two pieces of code (one for GPU and one for CPU).
> To avoid code redundancy, SINGA adds one function in Blob class
> {code}
> xpu_data();
> {code}
> xpu is cpu or gpu and is defined at compile time.
> Users write one piece of code which calls xpu_data() to get data from Blob.
> Depending on the compilation option, it will return GPU data or CPU data.
> This ticket just replaces the cpu to xpu and test with xpu=cpu. The GPU
> support (i.e., xpu=gpu) will be added in next release.
> The disadvantage of using xpu is that users cannot choose the running mode
> after compilation, and have to decide the running mode at compile time.
