This Visual Studio Code extension provides a rich editor for

[SDFGs](http://spcl.inf.ethz.ch/dace/) with included profiling and

debugging, static analysis, and interactive optimization.



# Features



## SDFG Editor



The SDFG editor allows changing of all editable SDFG properties and elements.

To allow for easier exploration of large graphs, most graph elements can be

collapsed into a smaller, more compact representation. A number of viewing

options, like the hiding of access nodes, can further assist with the editing

of larger graphs.

## SDFG Optimization / Transformations



With the SDFG Editor, data-centric applications can be optimized interactively using transformations.



- A set of applicable performance optimizing transformations is shown in a

  sorted list in the side panel for each valid SDFG program.

- A description provides more information about each transformation.

- Transformations can be previewed before applying them to the SDFG.

- The transformation history allows easy undoing/redoing of specific

  optimization steps.

## Static Analysis



SDFGs can be statically analyzed for memory or compute bottlenecks using a

series of overlays, which highlight the number of arithmetic operations or the

amount of memory moved per graph element.

## Debugging



SDFGs can be run with a debugger, allowing the setting of breakpoints on the

graph. For this purpose, the extension will install the

[Python / C++ Debugger](https://marketplace.visualstudio.com/items?itemName=benjamin-simmonds.pythoncpp-debug)

extension.

## Profiling



A built-in profiling run configuration allows SDFG programs to be run multiple

times1 while recording the median runtime for each execution. This

median runtime is then reported back to you. Additionally, individual graph

elements can be instrumented with timers, which generates a detailed profiling

report after an SDFG's execution. This report can be loaded in an displayed via

overlay on top of the SDFG.



1 The number of executions per profiling run can be configured in

the `.dace.config`. This can be opened by typing `Open .dace.config` into the

command bar.



## Building SDFGs



Graph elements can be dynamically added and moved around, allowing the creation

of entire SDFGs from scratch.
