Detailed Description

Class to handle tactic timing info collected from builder.

The timing cache is created or initialized by IBuilderConfig. It can be shared across builder instances to accelerate the builder wallclock time.

Member Function Documentation

combine()

bool nvinfer1::ITimingCache::combine ( ITimingCache const &  inputCache, bool  ignoreMismatch  )

inlinenoexcept

Combine input timing cache into local instance.

This function allows combining entries in the input timing cache to local cache object.

Parameters

inputCache	The input timing cache.
ignoreMismatch	Whether or not to allow cache verification header mismatch.

Returns

True if combined successfully, false otherwise.

Append entries in input cache to local cache. Conflicting entries will be skipped The input cache must be generated by a TensorRT build of exact same version, otherwise combine will be skipped and return false. ignoreMismatch must be set to true if combining a timing cache created from a different device.

Warning

Combining caches generated from devices with different device properties may lead to functional/performance bugs!

reset()

bool nvinfer1::ITimingCache::reset ( )

inlinenoexcept

Empty the timing cache.

Returns

True if reset successfully, false otherwise.

serialize()

nvinfer1::IHostMemory * nvinfer1::ITimingCache::serialize ( ) const

inlinenoexcept

Serialize a timing cache to IHostMemory object.

This function allows serialization of current timing cache.

Returns

A pointer to a IHostMemory object that contains a serialized timing cache.
