Method Detail

checkArity
public void checkArity()
Description copied from class:HopCheck whether this Hop has a correct number of inputs. (Some Hops can have a variable number of inputs, such as DataOp, DataGenOp, ParameterizedBuiltinOp, ReorgOp, TernaryOp, QuaternaryOp, MultipleOp, DnnOp, and SpoofFusedOp.) Parameterized Hops (such as DataOp) can check that the number of parameters matches the number of inputs.- Specified by:

getOp
public Types.OpOp1 getOp()
-
getOpString
public String getOpString()
- Specified by:
getOpStringin classHop
-
isGPUEnabled
public boolean isGPUEnabled()
Description copied from class:HopIn memory-based optimizer mode (see OptimizerUtils.isMemoryBasedOptLevel()), the exectype is determined by checking this method as well as memory budget of this Hop. Please see findExecTypeByMemEstimate for more detail. This method is necessary because not all operator are supported efficiently on GPU (for example: operations on frames and scalar as well as operations such as table).- Specified by:
isGPUEnabledin classHop- Returns:
- true if the Hop is eligible for GPU Exectype.
-
isMultiThreadedOpType
public boolean isMultiThreadedOpType()
- Specified by:

constructLops
public Lop constructLops()
- Specified by:
constructLopsin classHop
-
computeMemEstimate
public void computeMemEstimate(MemoTable memo)
Description copied from class:HopComputes the estimate of memory required to store the input/output of this hop in memory. This is the default implementation (orchestration of hop-specific implementation) that should suffice for most hops. If a hop requires more control, this method should be overwritten with awareness of (1) output estimates, and (2) propagation of worst-case matrix characteristics (dimensions, sparsity). TODO remove memo table and, on constructor refresh, inference in refresh, single compute mem, maybe general computeMemEstimate, flags to indicate if estimate or not.- Overrides:
computeMemEstimatein classHop- Parameters:
memo- memory table
