SYCL Dispatch Module for TensorFieldView - Native Kernel Edition

This module provides the each macro for SYCL backend, using native pre-compiled C++ SYCL kernels instead of JIT-compiled OpenCL C.

Types

DispatchInfo = object kind*: DispatchKind lhsView*: string rhsViews*: seq[string] scalar*: float64 isComplex*: bool
DispatchKind = enum dkCopy, dkAdd, dkSub, dkMul, dkScalarMul, dkScalarAdd, dkMatMul, dkMatVec, dkMatAdd, dkVecAdd, dkStencilCopy, dkStencilScalarMul, dkStencilAdd, dkUnknown
ElementType = enum etFloat32, etFloat64, etInt32, etInt64: Element type for kernel dispatch
ExecOperand = object isTemp*: bool viewName*: string tempId*: int: Represents an operand: either a view name or a temp buffer ID
ExecPlan = object steps*: seq[ExecStep] numTemps*: int finalDest*: ExecOperand
ExecStep = object kind*: ExecStepKind dest*: ExecOperand srcA*: ExecOperand srcB*: ExecOperand scalar*: float64
ExecStepKind = enum eskCopy, eskAdd, eskSub, eskMatMul, eskMatVec, eskScalarMul, eskScalarAdd
ExprInfo = object kind*: ExprKind viewName*: string viewRank*: int isComplex*: bool isNeighborAccess*: bool scalar*: float64 scalarIm*: float64 left*, right*: ref ExprInfo
ExprKind = enum ekSiteProxy, ekMatMul, ekMatVec, ekMatAdd, ekMatSub, ekScalarMul, ekScalarAdd, ekLiteral, ekUnknown
KernelInfo = object views*: seq[ViewInfo] viewRanks*: Table[string, int] loopVar*: NimNode loopVarStr*: string outputRank*: int outputRows*: int outputCols*: int isComplex*: bool elemType*: ElementType stencilBindings*: seq[StencilBinding] hasStencil*: bool

proc analyzeExpr(n: NimNode; viewNames: seq[string]; nbrVarNames: seq[string] = @[]): ExprInfo {....raises: [], tags: [], forbids: [].}: Analyze an expression to determine its type and structure nbrVarNames: variable names that are stencil neighbor indices

macro each(x: ForLoopStmt): untyped: Transform a for loop over TensorFieldView into a SYCL kernel dispatch.
macro eachImpl(loopVar: untyped; lo: typed; hi: typed; body: typed): untyped: Internal typed macro - receives body with full type information. Generates runtime dispatch to native SYCL kernels.
