    Description

      EM now issues a number of Primitive Jobs request messages towards PP doing scanning. This takes place in TupleBPS::sendJobs(). The limit of a simultaneous outstanding PJ should become dynamic and its size must depend on a math model that takes the resources currently available into account on the nodes.
