## Get the openCL options

### Description

The functions gets the computing precision when compile the GPU code and the number of workers in a computing group.

### Usage

### Arguments

`opt` | The options that the function will return. It can be either 'all' or a vector of the option names.

### Details

The fields `default.float`, `default.int` and `default.index.type` are used to control the computing precision. When transferring data from R to GPU, if the data in R has a numeric or double storage mode, `default.float` will be used to convert data type. Similarly, If the data has an Integer storage model. `default.int` will be used.

`default.index.type` controls the variable type for the for loop index, variable dimension etc.

`default.thread.num` is used to control the number of workers in a group in openCL. It is not expected to be changed unless you know what you are doing.
