I just want to know if this project use GPU or not, because I ran this project on my computer and it didn't produce as much heat as when I ran Enstein@home.
p/s my English is bad since it's not my mother tounge:(

It supports Nvidia and AMD cards for windows and linux. It looks like you have Intel integrated graphics, which is not supported at this time. In the near future I hope to add support for Intel GPUs. Check back in a month or 2.
