Overview

Package aivm GPU backend — runtime-loaded plugin bridge.

Unlike cevm/cevm_cgo.go (which links libevm + libevm-gpu via pkg-config), AIVM resolves its GPU backend at PROCESS START via dlopen/dlsym against the lux-gpu-kernels plugin DSOs. This keeps the chains module compilable without the lux GPU plugin present in the build tree — the plugin is fully optional.

Lookup order (handled by backend.go): 

libluxgpu_backend_cuda.so       (Linux x86_64 + NVIDIA)
libluxgpu_backend_hip.so        (Linux x86_64 + AMD ROCm)
libluxgpu_backend_metal.dylib   (macOS Apple Silicon / Intel)
libluxgpu_backend_vulkan.so/.dylib   (any Vulkan ICD)
libluxgpu_backend_webgpu.so/.dylib   (Dawn / wgpu-native)

Each plugin exports six extern "C" host launchers per backend: 

lux_<backend>_aivm_attestation_apply
lux_<backend>_aivm_provenance_apply
lux_<backend>_aivm_anchor_apply
lux_<backend>_aivm_epoch_transition
lux_<backend>_aivm_inference_step
lux_<backend>_aivm_proof_verify

Struct layout matches ops/aivm/cuda/aivm_kernels_common.cuh byte-for-byte (asserted by init()). Pointer ABI is HOST pointers — the launcher does H2D-upload / dispatch / D2H-download internally.

Package aivm provides the AI Virtual Machine for the Lux network.

AIVM is the AI compute coordination layer. It works on ANY Lux L1/L2 (mainnet primary network, testnet, devnet, white-label chains) with NO trusted dealer, NO TEE requirement, and NO single point of trust.

Verification model (per VerificationMode):

  • ModeOptimistic (DEFAULT, public-BFT-safe): providers post results with hash-commitment + bond; N-block challenge period; uncontested results finalise; challenged results enter fraud-proof flow with slashing of the losing side. No TEE assumption. Works on any L1/L2 that has Pulsar/Corona for finality.

  • ModeMultiPartyRedundant: M-of-N validators run the same inference and consensus on the output hash. No single provider needs trust; malicious providers diverge from the majority and are slashed. Public-BFT-safe. Cost: M× compute per task.

  • ModeTEEAttested: when a provider has SGX/SEV-SNP/TDX/nvtrust available, the attestation is FOLDED INTO the trust score as an accelerator (skip the challenge period for high-trust-score providers). TEE never CHANGES the trust root — only reduces latency-to-finality for already-bonded providers.

The TEE path (luxfi/ai/pkg/attestation) is OPTIONAL across all modes. Setting RequireTEEAttestation=true is a deployment policy choice for permissioned/regulated subnets; the public-chain default is VerificationMode=ModeOptimistic + RequireTEEAttestation=false.

Other features:

  • Task submission and assignment (chain-agnostic)
  • Mining rewards (paid in the host chain's native token)
  • Optional anchoring to Q-Chain for cross-chain settlement (controlled by HostChainID: when "primary", anchor to Q-Chain; otherwise anchor to the host chain's own finality)

func ActiveGPUBackend added in v1.3.0 

func ActiveGPUBackend() *GPUBackend

ActiveGPUBackend returns the backend resolved at init time. Always non-nil — when no plugin loaded it returns a zero-value *GPUBackend whose IsAvailable() reports false. Callers test IsAvailable() / Kind() to decide whether to opt into the GPU path.

func (*GPUBackend) AnchorApply added in v1.3.0 

func (b *GPUBackend) AnchorApply(

	ops []InferenceOp,
	batchInputs []int8,
	batchOutputs []int8,
	results []InferenceResult,
) error

InferenceStep runs the deterministic int8 32→16→1 inference kernel. `batchInputs` is op_count × 32 bytes of input rows; `batchOutputs` receives op_count × 1 byte of output values. Determinism contract: byte-equal to the CPU reference + every other backend.

func (*GPUBackend) IsAvailable added in v1.3.0 

func (b *GPUBackend) IsAvailable() bool

IsAvailable reports whether the backend is loaded AND all six host launchers were successfully resolved. Used by vm.go's gpuAvailable().

func (vm *VM) FeePolicy() fee.Policy

FeePolicy exposes the chain's declared fee policy for diagnostics and the boot-time Validate gate.

func (*VM) GetBlock 

func (vm *VM) GetBlock(ctx context.Context, id ids.ID) (chain.Block, error)

GetBlock implements chain.ChainVM interface

func (*VM) GetBlockIDAtHeight 

func (vm *VM) GetBlockIDAtHeight(ctx context.Context, height uint64) (ids.ID, error)

GetBlockIDAtHeight implements chain.ChainVM interface

func (*VM) GetMerkleRoot 

func (vm *VM) GetMerkleRoot() [32]byte

func (*VM) GetRewardStats 

func (vm *VM) GetRewardStats(providerID string) (map[string]interface{}, error)

GetRewardStats returns reward statistics for a provider

func (*VM) GetStats 

func (vm *VM) GetStats() map[string]interface{}

GetStats returns VM statistics

func (*VM) GetTask 

func (vm *VM) GetTask(taskID string) (*aivm.Task, error)

GetTask returns a task by ID

func (*VM) HealthCheck 

func (vm *VM) HealthCheck(ctx context.Context) (chain.HealthResult, error)

HealthCheck implements chain.ChainVM interface

func (*VM) Initialize 

func (vm *VM) Initialize(ctx context.Context, init vmcore.Init) error

func (*VM) NewHTTPHandler 

func (vm *VM) NewHTTPHandler(ctx context.Context) (http.Handler, error)

NewHTTPHandler implements chain.ChainVM interface

func (*VM) ParseBlock 

func (vm *VM) ParseBlock(ctx context.Context, bytes []byte) (chain.Block, error)

ParseBlock implements chain.ChainVM interface

func (*VM) ParseVertex 

func (vm *VM) ParseVertex(ctx context.Context, b []byte) (vertex.Vertex, error)

ParseVertex deserializes a vertex from bytes.

func (*VM) RegisterProvider 

func (vm *VM) RegisterProvider(provider *aivm.Provider) error

RegisterProvider registers a new AI compute provider.

Public-BFT-safe path (VerificationMode=ModeOptimistic, default):

  • Provider locks MinProviderBond in the host chain's escrow
  • TEE attestation is OPTIONAL — providers without TEE register under the optimistic-verification flow (challenge period + fraud proofs handle correctness without trusting the provider)

Permissioned path (RequireTEEAttestation=true, opt-in):

  • Provider MUST present valid TEE attestation
  • TrustScore must meet MinTrustScore
  • Used on permissioned subnets where the validator set vets hardware operators by policy

func (*VM) SetPreference 

func (vm *VM) SetPreference(ctx context.Context, id ids.ID) error

SetPreference implements chain.ChainVM interface

func (*VM) SetState 

func (vm *VM) SetState(ctx context.Context, state uint32) error

SetState implements chain.ChainVM interface

func (*VM) Shutdown 

func (vm *VM) Shutdown(ctx context.Context) error

Shutdown shuts down the VM

func (*VM) SubmitResult 

func (vm *VM) SubmitResult(result *aivm.TaskResult) error

SubmitResult submits a task result

func (*VM) SubmitTask 

func (vm *VM) SubmitTask(task *aivm.Task) error

SubmitTask submits a new AI task. This is the canonical user-task admission point on A-Chain — the HTTP /tasks handler routes through here. The FeePolicy gate refuses zero-fee tasks before they touch the core queue. Internal callers (consensus replay) bypass by reaching vm.core.SubmitTask directly.

func (*VM) VerifyGPUAttestation 

func (vm *VM) VerifyGPUAttestation(att *attestation.GPUAttestation) (*attestation.DeviceStatus, error)

VerifyGPUAttestation verifies GPU attestation (local nvtrust - no cloud)

func (*VM) Version 

func (vm *VM) Version(ctx context.Context) (string, error)

Version implements chain.ChainVM interface

func (*VM) WaitForEvent 

func (vm *VM) WaitForEvent(ctx context.Context) (vmcore.Message, error)

WaitForEvent implements chain.ChainVM interface

type VerificationMode added in v1.2.6 

type VerificationMode uint8

VerificationMode selects the AIVM result-verification strategy.

Public chains MUST use ModeOptimistic or ModeMultiPartyRedundant — these are public-BFT-safe and do not require any single trusted party. ModeTEEAttested is permitted but the TEE is treated as acceleration, never as the trust root. 

const (
	// ModeOptimistic is the default for public chains.
	// Providers post results with bond. N-block challenge period.
	// Public-BFT-safe — anyone can submit a fraud proof.
	ModeOptimistic VerificationMode = 0

	// ModeMultiPartyRedundant has M-of-N providers run the same task;
	// consensus on the result hash. Divergent providers are slashed.
	// Public-BFT-safe — no single provider can corrupt the result.
	ModeMultiPartyRedundant VerificationMode = 1

	// ModeTEEAttested is OPT-IN. Providers with valid TEE attestation
	// can shortcut the challenge period. TEE never changes the trust
	// root; it accelerates settlement for high-trust providers.
	// Use only on permissioned/regulated subnets where TEE-vendor
	// trust is acceptable; not the default for public mainnet.
	ModeTEEAttested VerificationMode = 2
)

type VerifyAttestationRequest 

type VerifyAttestationRequest struct {
	GPUAttestation *attestation.GPUAttestation `json:"gpu_attestation"`
}

VerifyAttestationRequest is the request for verifying attestation
