- `FAST`, or `2`: Fast Find: Checks the [Find-Db](https://rocmsoftwareplatform.github.io/MIOpen/doc/html/finddb.html) for an entry. If there is a Find-Db hit, use that entry. If there is a miss, utilize the Immediate mode fallback. If Start-up times are expected to be faster, but worse GPU performance.
- `HYBRID`, or `3`, or unset `MIOPEN_FIND_MODE`: Hybrid Find: Checks the [Find-Db](https://rocmsoftwareplatform.github.io/MIOpen/doc/html/finddb.html) for an entry. If there is a Find-Db hit, use that entry. If there is a miss, use the existing Find machinery. Slower start-up times than Fast Find, but no GPU performance drop.

As of MIOpen 2.4, the default mode is set to `HYBRID` mode as default. To run the full `NORMAL` Find mode, set the environment as:

## MIOpen Release notes


### 06/30/2020 [ 2.5.0 ]
### 07/31/2020 [ 2.6.0 ]

- This release contains convolution performance improvements, improved multi-threading behavior, and improved stability for half precision convolutions. Initial iteration time has been reduced with the introduction of hybrid find mode. Builds for a static library have been refined for this release.

- Added MIOPEN_FIND_MODE=3 as the new default convolution Find mode; see documentation [here](https://rocmsoftwareplatform.github.io/MIOpen/doc/html/find_and_immediate.html#find-modes) for details
- Added a more runtime-parameterized version of pooling to reduce the number of online compilations
- Improved the performance of backwards spatial batch normalization for small images
- Fixed issue with std::logic_error in SQLite deleter [#306](https:/ROCmSoftwarePlatform/MIOpen/issues/306)
- Fixed issues with half precision stability for convolutions
- Fixed issues with multi-threaded SQLite database accesses
- Fixed issues with 3-D convolutions and incorrect parameters
- Fixed various issues with implicit GEMM static assert failures
- Removed inactive implicit GEMM convolution solvers
- Removed SCGEMM convolutional algorithm from MIOpen

### 07/10/2020 [ 2.5.0 ]

- This release contains convolution performance improvements, various minor fixes and documentation updates.
