In datacomm-1.pg file, I had to set the RobotCnt variable to N in R**N,
is used to set the request rate per robot.
On a related note, PolyMix-1 and DataComm-1 workloads define a constant request
rate. But I see graphs of Req/Sec vs Mean Resp Time graphs with Req/Sec
constantly increasing. How were these graphs generated? When I run those
workloads I pretty much see almost a constant request rate.
Thanks for your patience in answering all my newbie questions.

Well, perhaps the request rate those 10 robots generate is too high for
your configuration? As a rule of thumb, the close-to-minimum number of
FDs required for PolyMix-2 can be computed as
open_conn_lmt * mean_response_time * total_req_rate
total_req_rate = number_of_robots * req_rate_per_robot
Make sure that you are not multiplying the desired total request rate by
10 in your configurations!
For DataComm and PolyMix-1, there is no open_conn_lmt; set it to 1 in
the formula above.
