|
||||
<span class="sd"> Ease-of-use interface for constructing, compiling, and running GEMMs.</span>
|
||||
|
||||
<span class="sd"> The ``Gemm`` interface is meant to allow one to easily instantiate, compile, and run</span>
|
||||
<span class="sd"> GEMM operations in CUTLASS via Python, without specifying many configuration parameters.</span>
|
||||
<span class="sd"> Under the hood, the interface will select sensible default parameters for the many template</span>
|
||||
<span class="sd"> parameters for CUTLASS GEMMs.</span>
|
||||
|
||||
<span class="sd"> Note: optimal performance is not to be expected from this interface. To achieve optimal</span>
|
||||
<span class="sd"> performance, one should specify and tune each configuration parameter.</span>
|
||||
|
||||
<span class="sd"> The simplest example of using this interface is the following:</span>
|
||||
|
||||
<span class="sd"> .. highlight:: python</span>
|
||||
<span class="sd"> .. code-block:: python</span>
|
||||
|
||||
<span class="sd"> # A, B, C, and D are torch/numpy/cupy tensor objects</span>
|
||||
<span class="sd"> plan = cutlass.op.Gemm(A, B, C, D)</span>
|
||||
<span class="sd"> plan.run()</span>
|
||||
|
||||
|
||||
<span class="sd"> One can also use the interface by specifying data types of operands at construction</span>
|
||||
<span class="sd"> and using different tensor objects with these data types at runtime:</span>
|
||||
|
||||
<span class="sd"> .. highlight:: python</span>
|
||||
<span class="sd"> .. code-block:: python</span>
|
||||
|
||||
<span class="sd"> # The following is shorthand for:</span>
|
||||
<span class="sd"> # cutlass.op.Gemm(element_A=torch.float32, element_B=torch.float32,</span>
|
||||
<span class="sd"> # element_C=torch.float32, element_D=torch.float32,</span>
|
||||
<span class="sd"> # element_accumulator=torch.float32,</span>
|
||||
<span class="sd"> # layout=cutlass.LayoutType.RowMajor)</span>
|
||||
<span class="sd"> plan = cutlass.op.Gemm(element=torch.float32, layout=cutlass.LayoutType.RowMajor)</span>
|
||||
|
||||

|

<span class="sd"> Ease-of-use interface for constructing, compiling, and running GEMMs.</span>
|
||||
|
||||
<span class="sd"> The ``GroupedGemm`` interface is meant to allow one to easily instantiate, compile, and run</span>
|
||||
<span class="sd"> grouped GEMM operations in CUTLASS via Python, without specifying many configuration parameters.</span>
|
||||
<span class="sd"> Under the hood, the interface will select sensible default parameters for the many template</span>
|
||||
<span class="sd"> parameters for CUTLASS grouped GEMMs.</span>
|
||||
|
||||
<span class="sd"> Note: optimal performance is not to be expected from this interface. To achieve optimal</span>
|
||||
<span class="sd"> performance, one should specify and tune each configuration parameter.</span>
|
||||
|
||||
<span class="sd"> The simplest example of using this interface is the following:</span>
|
||||
|
||||
<span class="sd"> .. highlight:: python</span>
|
||||
<span class="sd"> .. code-block:: python</span>
|
||||
