Call to execute the calculation on the reserved DFE engines.

Parameters

rows	The number of rows in the input matrix
cols	the number of columns in the input matrix
gates	The metadata describing the gates to be applied on the input
gatesNum	The number of the chained up gates.
gateSetNum	Integer descibing how many individual gate chains are encoded in the gates input.
traceOffset	In integer describing an offset in the trace calculation
trace	The trace of the transformed unitaries are returned through this pointer

Returns

Return with 0 on success
