First, we detect the kernel's hot spots correlating problematic source code lines (previously detected by the optimization parser module) with their corresponding operations. By doing so, we can precisely depict which parts of the kernel account for most of its execution time. We describe the ...
On the other hand, combining application-dependent optimizations on the source code and exploration of optimization parameters as it is achieved with ATLAS, has been shown as a promising path to achieve high performance. Yet, hand-tuned codes such as in the MKL library still outperforms ATLAS ...
We also implement the domain-specific optimization of convolution in AKG. Moreover, to achieve the optimal performance, we introduce complementary optimizations in code generation, which is followed by an auto-tuner. We conduct extensive experiments on benchmarks ranging from single operators to end-...

You can use this syntax to optimize on compact model size instead of cross-validation loss, and to perform a set of multiple optimization problems that have the same options but different constraint bounds.Examples collapse all Train Kernel Classification Model Copy Code Copy Command Train a binary...
GPU Coder also performs an optimization that minimizes the number of cudamMemcpy function calls. In this example, a copy of the input x is in the GPU, no extra cudamMemcpy is required between scalars_kernel2 and scalars_kernel3. In addition to memory optimization, any sequential code ...
