+# DiscoPoP Optimizer
+## Executable
+`discopop_optimizer`
+
+## Purpose
+- Propose a mapping of the parallel patterns identified by the [DiscoPoP explorer](../tools/Explorer.md) to various devices available to the system.
+- Identify and report optimizations for the identified patterns (e.g. adding a `collapse(3)` clause to parallel loops).
+- Create a beneficial combination of potentially multiple patterns to achieve a improved speedup and remove the need to manually select combinable patterns.
+
+## Required input
+- [Filemapping](../data/Filemapping.md)
+- [Profiling and instrumentation output](../data/Profiling_and_instrumentation_output.md)
+- Parallel patterns created by [DiscoPoP explorer](../tools/Explorer.md)
+
+## Optional input
+- System information and overhead measurements obtained via the [OpenMP Microbenchmark suite](https://github.com/discopop-project/OpenMP-Microbench)
+
+## Output
+Identified optimizations and combinations are stored by extending the original set of [parallel patterns](../data/Parallel_patterns.md). The updated set is stored in a file named `.discopop/optimizer/patterns.json` by default. Similar to the original set of patterns, these can be imported by various other tools in the framework.
+
+## Note
+For a more detailed description of the available run-time arguments, please refer to the help string of the respective tool.
