+<h1>Software Stack<a class="headerlink" href="#software-stack" 
title="Permalink to this headline">¶</a></h1>
+<p>SINGA’s software stack includes three major components, namely, core, IO 
and
+model. Figure 1 illustrates these components together with the hardware.
+The core component provides memory management and tensor operations;
+IO has classes for reading (and writing) data from (to) disk and network; The
+model component provides data structures and algorithms for machine learning 
models,
+e.g., layers for neural network models, optimizers/initializer/metric/loss for
+general machine learning models.</p>

+<span><strong>Figure 1 - SINGA V1 software stack.</strong></span><div 
class="section" id="core">
+<h2>Core<a class="headerlink" href="#core" title="Permalink to this 
headline">¶</a></h2>
+<p><a class="reference external" href="tensor.html">Tensor</a> and <a 
class="reference external" href="device.html">Device</a> are two core 
abstractions in SINGA. Tensor class represents a
+multi-dimensional array, which stores model variables and provides linear 
algebra
+operations for machine learning
+algorithms, including matrix multiplication and random functions. Each tensor
+instance (i.e. a tensor) is allocated on a Device instance.
+Each Device instance (i.e. a device) is created against one hardware device,
+e.g. a GPU card or a CPU core. Devices manage the memory of tensors and execute
+tensor operations on its execution units, e.g. CPU threads or CUDA streams.</p>
+<p>Depending on the hardware and the programming language, SINGA have 
implemented
+the following specific device classes:</p>
+<ul class="simple">
+<li><strong>CudaGPU</strong> represents an Nvidia GPU card. The execution 
units are the CUDA streams.</li>
+<li><strong>CppCPU</strong> represents a normal CPU. The execution units are 
the CPU threads.</li>
+<li><strong>OpenclGPU</strong> represents normal GPU card from both Nvidia and 
AMD.
+The execution units are the CommandQueues. Given that OpenCL is compatible with
+many hardware devices, e.g. FPGA and ARM, the OpenclGPU has the potential to be
+extended for other devices.</li>
+</ul>
+<p>Different types of devices use different programming languages to write the 
kernel
+functions for tensor operations,</p>
+<ul class="simple">
+<li>CppMath (tensor_math_cpp.h) implements the tensor operations using Cpp for 
CppCPU</li>
+<li>CudaMath (tensor_math_cuda.h) implements the tensor operations using CUDA 
for CudaGPU</li>
+<li>OpenclMath (tensor_math_opencl.h) implements the tensor operations using 
OpenCL for OpenclGPU</li>
+</ul>
+<p>In addition, different types of data, such as float32 and float16, could be 
supported by adding
+the corresponding tensor functions.</p>
+<p>Typically, users would create a device instance and pass it to create 
multiple
+tensor instances. When users call the Tensor functions, these function would 
invoke
+the corresponding implementation (CppMath/CudaMath/OpenclMath) automatically. 
In
+other words, the implementation of Tensor operations is transparent to 
users.</p>
+<p>Most machine learning algorithms could be expressed using (dense or sparse) 
tensors.
+Therefore, with the Tensor abstraction, SINGA would be able to run a wide 
range of models,
+including deep learning models and other traditional machine learning 
models.</p>
+<p>The Tensor and Device abstractions are extensible to support a wide range 
of hardware device
+using different programming languages. A new hardware device would be 
supported by
+adding a new Device subclass and the corresponding implementation of the Tensor
+operations (xxxMath).</p>
+<p>Optimizations in terms of speed and memory could be implemented by Device, 
which
+manages both operation execution and memory malloc/free. More optimization 
details
+would be described in the <a class="reference external" 
href="device.html">Device page</a>.</p>
+</div>
+<div class="section" id="model">
+<h2>Model<a class="headerlink" href="#model" title="Permalink to this 
headline">¶</a></h2>
+<p>On top of the Tensor and Device abstractions, SINGA provides some higher 
level
+classes for machine learning modules.</p>
+<ul class="simple">
+<li><a class="reference external" href="layer.html">Layer</a> and its 
subclasses are specific for neural networks. Every layer provides
+functions for forward propagating features and backward propagating gradients 
w.r.t the training loss functions.
+They wraps the complex layer operations so that users can easily create neural 
nets
+by connecting a set of layers.</li>
+<li><a class="reference external" href="initializer.html">Initializer</a> and 
its subclasses provide variant methods of initializing
+model parameters (stored in Tensor instances), following Uniform, Gaussian, 
etc.</li>
+<li><a class="reference external" href="loss.html">Loss</a> and its subclasses 
defines the training objective loss functions.
+Both functions of computing the loss values and computing the gradient of the 
prediction w.r.t the
+objective loss are implemented. Example loss functions include squared error 
and cross entropy.</li>
+<li><a class="reference external" href="metric.html">Metric</a> and its 
subclasses provide the function to measure the
+performance of the model, e.g., the accuracy.</li>
+<li><a class="reference external" href="optimizer.html">Optimizer</a> and its 
subclasses implement the methods for updating
+model parameter values using parameter gradients, including SGD, AdaGrad, 
RMSProp etc.</li>
+</ul>
+</div>
+<div class="section" id="io">
+<h2>IO<a class="headerlink" href="#io" title="Permalink to this 
headline">¶</a></h2>
+<p>The IO module consists of classes for data loading, data preprocessing and 
message passing.</p>
+<ul class="simple">
+<li>Reader and its subclasses load string records from disk files</li>
+<li>Writer and its subclasses write string records to disk files</li>
+<li>Encoder and its subclasses encode Tensor instances into string records</li>
+<li>Decoder and its subclasses decodes string records into Tensor 
instances</li>
+<li>Endpoint represents a communication endpoint which provides functions for 
passing messages to each other.</li>
+<li>Message represents communication messages between Endpoint instances. It 
carries both meta data and payload.</li>

+<p><strong>Disclaimer</strong></p>
+<p>Apache SINGA is an effort undergoing incubation at The Apache Software
+Foundation (ASF), sponsored by the name of Apache Incubator PMC. Incubation is
+required of all newly accepted projects until a further review indicates that
+the infrastructure, communications, and decision making process have stabilized
+in a manner consistent with other successful ASF projects. While incubation
+status is not necessarily a reflection of the completeness or stability of the
+code, it does indicate that the project has yet to be fully endorsed by the
+ASF.</p>
