ggml : GPU-accelerated token generation ( #1412 )
...
* CUDA kernel for q4_0 dequant. + mat. vec. mult.
* Added q4_1 via template
* Added missing __syncthreads();
* --gpu_layers -> --gpu-layers
* Shorter dequantize_mul_mat_vec line
* q5_0 dequantize_mul_mat kernel
* More readable dequantize_mul_mat_vec logic
* dequantize_mul_mat_vec kernels for q5_1, q8_0, f16
* llama : offload "output" tensor to GPU too + coding style fixes
