The first request after an unload transparently reloads the model and is served once it is ready, so the GPU can be used by other workloads while a model is idle. + +Notes: +- Only inference requests reset the idle timer; status/metrics/health endpoints do not keep a model loaded. +- The first request after an idle unload pays the reload latency. Combine with [model caching](../model_cache.md) (`--cache_dir`) so the reload is a fast cache import rather than a full recompile. +- The graph reports as `AVAILABLE` while idle-unloaded (it auto-reloads on demand). The `ovms_graph_loaded` metric reports `1` when loaded and `0` when idle-unloaded. +- Supported for LLM continuous-batching graphs. Graphs containing Python nodes are not supported with this setting. ### Caching settings The value of `cache_size` might have performance and stability implications. It is used for storing LLM model KV cache data. Adjust it based on your environment capabilities, model size and expected level of concurrency. diff --git a/src/dags/pipelinedefinitionstatus.cpp b/src/dags/pipelinedefinitionstatus.cpp index 5fb27479b0..17afaa3a0e 100644 --- a/src/dags/pipelinedefinitionstatus.cpp +++ b/src/dags/pipelinedefinitionstatus.cpp @@ -35,7 +35,8 @@ const std::string& pipelineDefinitionStateCodeToString(PipelineDefinitionStateCo {PipelineDefinitionStateCode::LOADING_PRECONDITION_FAILED_REQUIRED_REVALIDATION, "LOADING_PRECONDITION_FAILED_REQUIRED_REVALIDATION"}, {PipelineDefinitionStateCode::AVAILABLE_REQUIRED_REVALIDATION, "AVAILABLE_REQUIRED_REVALIDATION"}, {PipelineDefinitionStateCode::AVAILABLE, "AVAILABLE"}, - {PipelineDefinitionStateCode::RETIRED, "RETIRED"}}; + {PipelineDefinitionStateCode::RETIRED, "RETIRED"}, + {PipelineDefinitionStateCode::UNLOADED, "UNLOADED"}}; return names.at(code); } @@ -62,6 +63,9 @@ StateKeeper BeginState::handle(const RetireEvent& e) const { throw std::logic_error(INVALID_TRANSITION_MESSAGE); return {}; } +StateKeeper BeginState::handle(const UnloadEvent& e) const { + return {}; // unload is a no-op when not yet loaded +} PipelineDefinitionStateCode ReloadState::getStateCode() const { return code; @@ -84,6 +88,9 @@ StateKeeper ReloadState::handle(const RetireEvent& e) const { throw std::logic_error(INVALID_TRANSITION_MESSAGE); return {}; } +StateKeeper ReloadState::handle(const UnloadEvent& e) const { + return {}; // unload is a no-op while reloading +} PipelineDefinitionStateCode AvailableState::getStateCode() const { return code; @@ -105,6 +112,9 @@ StateChanger AvailableState::handle(const UsedMod StateChanger AvailableState::handle(const RetireEvent& e) const { return {}; } +StateChanger AvailableState::handle(const UnloadEvent& e) const { + return {}; +} PipelineDefinitionStateCode AvailableRequiredRevalidation::getStateCode() const { return code; @@ -124,6 +134,9 @@ StateKeeper AvailableRequiredRevalidation::handle(const UsedModelChangedEvent& e StateChanger AvailableRequiredRevalidation::handle(const RetireEvent& e) const { return {}; } +StateKeeper AvailableRequiredRevalidation::handle(const UnloadEvent& e) const { + return {}; // unload is a no-op in AVAILABLE_REQUIRED_REVALIDATION +} PipelineDefinitionStateCode LoadingPreconditionFailedState::getStateCode() const { return code; @@ -145,6 +158,10 @@ StateChanger LoadingPreconditio StateChanger LoadingPreconditionFailedState::handle(const RetireEvent& e) const { return {}; } +StateChanger LoadingPreconditionFailedState::handle(const UnloadEvent& e) const { + // Revert a failed wake-up reload back to UNLOADED so the next request retries. + return {}; +} PipelineDefinitionStateCode LoadingFailedLastValidationRequiredRevalidation::getStateCode() const { return code; @@ -164,6 +181,9 @@ StateKeeper LoadingFailedLastValidationRequiredRevalidation::handle(const UsedMo StateChanger LoadingFailedLastValidationRequiredRevalidation::handle(const RetireEvent& e) const { return {}; } +StateKeeper LoadingFailedLastValidationRequiredRevalidation::handle(const UnloadEvent& e) const { + return {}; // unload is a no-op when loading already failed +} PipelineDefinitionStateCode RetiredState::getStateCode() const { return code; @@ -187,6 +207,31 @@ StateKeeper RetiredState::handle(const RetireEvent& e) const { throw std::logic_error(INVALID_TRANSITION_MESSAGE); return {}; } +StateKeeper RetiredState::handle(const UnloadEvent& e) const { + return {}; // unload is a no-op when already retired +} + +PipelineDefinitionStateCode UnloadedState::getStateCode() const { + return code; +} +StateChanger UnloadedState::handle(const ReloadEvent& e) const { + return {}; // wake-up: transition through reload path +} +StateChanger UnloadedState::handle(const RetireEvent& e) const { + return {}; // config removal while unloaded +} +StateChanger UnloadedState::handle(const ValidationPassedEvent& e) const { + return {}; // defensive: if validation passes directly, go available +} +StateKeeper UnloadedState::handle(const ValidationFailedEvent& e) const { + return {}; +} +StateKeeper UnloadedState::handle(const UsedModelChangedEvent& e) const { + return {}; +} +StateKeeper UnloadedState::handle(const UnloadEvent& e) const { + return {}; // already unloaded, idempotent +} PipelineDefinitionStatus::PipelineDefinitionStatus(const std::string& type, const std::string& name) : MachineState(type, name) {} @@ -233,6 +278,15 @@ std::tuple PipelineDefinitionSta ModelVersionState::END, ModelVersionStatusErrorCode::OK}; + case PipelineDefinitionStateCode::UNLOADED: + // Report AVAILABLE: the graph auto-reloads on the next inference request, + // so health checks and routing should treat it as available.
