Overview

Test executable for validating Triton's concurrent multi-threaded inference using the in-process C API.

Description

multi_server.cc creates an in-process Triton server, loads a model, and spawns multiple concurrent inference threads to validate thread safety. Each thread independently sends inference requests using configurable memory types (system, pinned, GPU) with asynchronous inference using promises/futures for synchronization. The program validates that concurrent requests produce correct results.

Usage

Used as a QA test executable to verify Triton's thread safety and concurrent inference capability. Not a library for import.
