Computes an estimate for the time needed by the CPU to execute (including memory access) an instruction by providing number of floating operations.

Parameters:

nflop - number FLOP to execute a target CPU operation

numPartitions - number partitions used to execute the target operation; not bound to any of the input/output statistics object to allow more flexibility depending on the corresponding instruction

executorMetrics - metrics for the executor utilized by the Spark cluster

output - statistics for the output variable

inputs - arrays of statistics for the output variable

Returns:

time estimate
