Get OpenCL working

You need to have OpenCL support on your system. OpenCL usually comes with your graphics drivers. On Windows it should work out of the box on linux you will need to install them separately.

You can always list the providers by using

clinfo -l

That's separate command NOT shipped with post implementation. Please refer to your system installation manual of clinfo for installation instructions.

Remarks

• -id and -commitmentAtxId are required because they are committed to the generated data.
• If -id isn't provided, the id (public key) will be auto-generated, while saving key.bin in -datadir.
• If postcli is called multiple times on a given -datadir, config mismatch error is likely to occur. In this case, the -reset flag can be used to easily clean the previous instance.
