	)

Execution units for use in a responder equivalent for a superscale design with multiple threads

Parameters

seed	- seed for random number generator for randomizing latencies
use_crypto	- use cryptographic quality random numbers
logger	- object for logging output
outputring	- output work queue to write processed packet and status
memory	- output work queue to write processed packet and status
units	- units of measure for latency (s, ms, us, ns)
read_latency	- latency of reads, can be a range (i.e., "4..30")
compute_latency	- latency of computation, can be a range (i.e., "100..200")
write_latency	- latency of writes, can be a range (i.e., "50..80")

inlen	- Length of the input data
outaddr	- address to write output to
outlen	- Length of the desired output
flows	- map to all available flows
protect	- apply protection to the packet
stream	- stream for encapsulation
