OpenCL Runtime for Intel Xeon Processors Wmvare VPS

I rent a VPS.

OS: Debian 9, CLI only.

My problem is that the server is very slow, (I use hashcat) so I would like to know:

Should I install the driver for OpenCL Runtime for Intel Core and Intel Xeon Processors?

1. Do I need only the OpenCL™ 2.0 CPU Driver Package for Linux*(64-bit)?
2. Shall I install   Intel® SDK for OpenCL™ Applications 2016 R2 for Linux* (64-bit), too?
3. My VPS is not a GPU accelerated server. I would like to increase the server's CPU capabilities. Is it possible to increase it by installing these 2 software ?

Thank your help.
