### How can I check that my specific device is supported by the driver?
To check support for any device, you can follow these steps:
1. Go to [Ark]( https://ark.intel.com) and find your Device ID
1. Find the corresponding device ID label in [GMM]( https://github.com/intel/gmmlib/blob/master/Source/inc/common/igfxfmid.h)
1. Check if this device ID label is enumerated in the [supported device list](https://github.com/intel/compute-runtime/blob/master/runtime/dll/linux/devices/devices_base.inl)
Cached kernels can be stored in a different directory than the default one. This is useful when the application is installed into a directory for which the user doesn't have permissions.
#### Linux configuration
Set the environment variable named `cl_cache_dir` to new location of cl_cache directory.
#### Example:
If the application's directory is `/home/user/Document`, by default cl_cache will be stored in `/home/user/Document/cl_cache`.
If the new path should be `/home/user/Desktop/cl_cache_place`, set environment variable `cl_cache_dir` to `/home/user/Desktop/cl_cache_place`.
Subsequent application runs with passed source code and `cl_cache_dir` environment variable set will reuse previously cached kernel binaries instead of compiling kernels from source.
#### Windows configuration
To set the new location of cl_cache directory - in the registry `HKEY_LOCAL_MACHINE\SOFTWARE\Intel\IGFX\OCL`:
1. add key `cl_cache_dir`
1. add string value named <path_to_app> to `cl_cache_dir` key
1. set data of added value to desired location of cl_cache
#### Example:
If application is located in `C:\Program Files\application\app.exe`, by default cl_cache will be stored in `C:\Program Files\application\cl_cache`.
If the new path should be `C:\Users\USER\Documents\application\cl_cache`, to subkey `HKEY_LOCAL_MACHINE\SOFTWARE\Intel\IGFX\OCL\cl_cache_dir` add string value named `C:\Program Files\application\app.exe` with data `C:\Users\USER\Documents\application\cl_cache`.
e.g.
string value : `HKEY_LOCAL_MACHINE\SOFTWARE\Intel\IGFX\OCL\cl_cache_dir\C:\Program Files\application\app.exe`
data : `C:\Users\USER\Documents\application\cl_cache`
Neo will look for string value (REG_SZ) `C:\Program Files\application\app.exe` in key `HKEY_LOCAL_MACHINE\SOFTWARE\Intel\IGFX\OCL\cl_cache_dir`. Data of this string value will be used as new cl_cache dump directory for this specific application.
1. Not thread safe. (Workaround: Make sure your clBuildProgram calls are executed in thread safe fashion.)
1. Binary representation may not be compatible between various versions of NEO and IGC drivers. (Workaround: Manually empty *cl_cache* directory prior to update)
1. Cache is not automatically cleaned. (Workaround: Manually empty *cl_cache* directory)
1. Cache may exhaust disk space and cause further failures. (Workaround: Monitor and manually empty *cl_cache* directory)
