Abstract

A mechanism is described for facilitating smart distribution of resources for deep learning autonomous machines. A method of embodiments, as described herein, includes detecting one or more sets of data from one or more sources over one or more networks, and introducing a library to a neural network application to determine optimal point at which to apply frequency scaling without degrading performance of the neural network application at a computing device.

a graphics processor to:
detect one or more sets of data from one or more sources over one or more networks;
cause a neural network application to implement a library comprising machine learning primitives, wherein the machine learning primitives are usable to analyze a skew pattern observed in a distributed gradient synchronization implemented by the neural network application;
implement, using the neural network application, the distributed gradient synchronization using a tree structure such that local weight vectors start at one or more nodes represented as leaves of the tree structure and communicate up to a root of the tree structure;
determine, using the machine learning primitives of the library as implemented by the neural network application, a point to apply frequency scaling in the graphics processor that does not degrade performance of the neural network application, the point determined based on analysis of the skew pattern generated by the distributed gradient synchronization implemented via the tree structure; and
determine, using the library as implemented by the neural network application, a core frequency of the frequency scaling applied at the point, wherein the library is to account for skew characteristics associated with the distributed gradient synchronization to decide the core frequency.

3. The apparatus of claim 1 , wherein the graphics processor is further operable to introduce a sparse matrix representation for weights to overlap communication and computation across the one or more nodes associated with the neural network application to reduce communication costs.

4. The apparatus of claim 1 , wherein the graphics processor is further to automatically analyze failed execution of programs including or relevant to the neural network application to obtain insights on one or more faults of hardware performance counters.

5. The apparatus of claim 4 , wherein the graphics processor is further to provide one or more of successful execution information obtained from successful execution of programs and failed execution information obtained from failed execution of programs to a trained network model to seek out one or more of the hardware performance counters that are regarded as faulty or outside a range of approval.

6. The apparatus of claim 1 , wherein the graphics processor is further to perform local error propagation by computing high precision and low precision for local weights and compute local errors at each of the one or more nodes, wherein performing the local error propagation further comprises facilitating weight synchronization across the one or more nodes to track the local errors for accuracy and reduced communication.

7. The apparatus of claim 1 , wherein the apparatus comprises an autonomous machine comprising one or more of a vehicle, a device, or an equipment, wherein the autonomous machine comprises one or more processors including the graphics processor, wherein the graphics processor is co-located with an application processor on a common semiconductor package.
