Computation of T

The computation of T takes place on an instance of the agent for each problem request and for each computational server M. This computation uses all the parameters listed in the preceding section. We distinguish three different classes of parameter:

• The client-dependent parameters
  1. The size of the data to send
  2. The size of the result to be received
  3. The size of the problem
• The static server-dependent parameters
  1. The network characteristics between the local host and M
  2. The complexity of the algorithm to be used on M
  3. The raw performance of M
• The dynamic server-dependent parameters
  1. The workload of M

The client-dependent parameters are included in the problem request sent by the client to the agent. Their evaluation is therefore completely straightforward. The static server-dependent parameters are generally assessed once, when a new server contacts the other NetSolve servers already in the configuration.

• Network Characteristics.
• Complexity of the Algorithm.
• Raw Performance.
