## hipFile 0.3.0 for ROCm 7.14.0
|
|
|
|
### Added
|
|
|
|
* Examples can be installed on `share/doc/examples/*` by setting `AIS_INSTALL_EXAMPLES` to `ON`.
|
|
* An additional check has been added to the Fastpath/AIS backend to ensure the HIP Runtime is initialized, preventing segmentation faults when using the HIP Runtime.
|
|
* Added file type and file system validation in Fastpath. Fastpath will only accept I/O targeting block devices or regular files backed by xfs or ext4 with ordered journaling mode. Other file systems can be explicitly allowed via the `HIPFILE_UNSUPPORTED_FILE_SYSTEMS` environment variable.
|
|
|
|
### Changed
|
|
|
|
* `hipFileOpStatusError()` has been renamed to `hipFileGetOpErrorString()`.
|
|
* The `hipfile-doc` CMake target has been replaced with `doc`. The `AIS_BUILD_DOCS` CMake option must be enabled to build with this target.
|
|
* The CMake namespace has changed from `roc::` to `hip::`
|
|
* `AIS_BUILD_EXAMPLES` has been renamed to `AIS_INSTALL_EXAMPLES`
|
|
* `AIS_USE_SANITIZERS` now also enables the following sanitizers: integer, float-divide-by-zero, local-bounds, vptr, nullability (in addition to address, leak, and undefined). Sanitizers should also now emit usable stack trace info.
|
|
* The AIS optimized I/O path now automatically falls back to the POSIX I/O path if a failure occurs and the compatibility mode has not been disabled.
|
|
* The default CMake build type has changed from `Debug` to `RelWithDebInfo`
|
|
|
|
### Removed
|
|
|
|
* The rocFile library has been completely removed and the code is now a part of hipFile.
|
|
* The hipify patch was removed. hipify with hipFile support can be obtained from the main HIPIFY repo at https://github.com/ROCm/HIPIFY. The `amd-develop` branch has hipFile support, but this has not been officially released yet.
|
|
* The `AIS_USE_INTEGER_SANITIZER` CMake option has been removed. Use the `AIS_USE_SANITIZERS` option instead.
|
|
* Support for GNU sanitizers has been dropped in this release.
|
|
|
|
### Known issues
|
|
|
|
* Batch and async API calls are not supported on the AMD backend
|
|
* Poor performance with small I/O sizes (<= 64KiB) and many threads/processes
|
|
* Poor performance within QEMU virtual machine when PCIe devices are not attached to PCIe root ports
|
|
* High memory usage with many processes
|
|
* GPU resets encountered with many processes
