Improve calibration behaviour by implementing an XRootD overhead that depends on the runtime of the XRootD streaming computation.
The amount of overhead introduced can be set via the command line option
--xrd-flops-per-time
and has a default value of20000000000
estimated from job monitoring data of jobs without noticeable computation load (copyjobs). However, it can depend on other simulation parameters, e.g.--xrd-blocksize
, and therefore needs to be calibrated.
