I am new in this forum.
Is there any way to fetch a html webpage in device kernel function? I have searched in “GPU-accelerated libraries” but could not found any.
Nope. The GPU is not “autonomous” enough to run networking stacks.
You could look into Intel’s Xeon Phi technology. These coprocessor cores are versatile enough to run their own (scaled down) Linux kernel, and to do some network I/O.
