C API

extern "C" int32_t aclnnPidWindowedResidualDiagnostics( void* actual, void* predicted, void* metrics, void* autocorr, int64_t batch, int64_t sample_count, int64_t window_size, int64_t stride, int64_t max_lag, void* workspace, uint64_t workspace_size, void* stream); extern "C" uint64_t aclnnPidWindowedResidualDiagnosticsGetWorkspaceSize( int64_t batch, int64_t sample_count, int64_t window_size, int64_t stride, int64_t max_lag); extern "C" int64_t aclnnPidWindowedResidualDiagnosticsGetWindowCount( int64_t sample_count, int64_t window_size, int64_t stride);

Inputs

Outputs

The metric order is:

0 mean_residual 1 std_residual 2 mae 3 rmse 4 max_abs_residual 5 fit_percent 6 durbin_watson 7 ljung_box_q

Parameters

Workspace

CallaclnnPidWindowedResidualDiagnosticsGetWorkspaceSize(...)first and allocate a device workspace of at least that size. The current prototype only stores tiling metadata in workspace.

Return Value

• ACL_SUCCESS: launch accepted.
• ACL_ERROR_INVALID_PARAM: null pointer, invalid shape, invalid workspace, or invalid stream.

The call launches asynchronously onstream; callaclrtSynchronizeStream(stream)before reading outputs.

Example

const int64_t window_count = aclnnPidWindowedResidualDiagnosticsGetWindowCount(sample_count, window_size, stride); const uint64_t workspace_size = aclnnPidWindowedResidualDiagnosticsGetWorkspaceSize( batch, sample_count, window_size, stride, max_lag); aclnnPidWindowedResidualDiagnostics( d_actual, d_predicted, d_metrics, d_autocorr, batch, sample_count, window_size, stride, max_lag, workspace, workspace_size, stream);
