balancing

In computing, load balancing refers to the process of distributing a set of tasks over a set of resources (computing units), with the aim of making their overall processing more efficient. Load balancing can optimize the response time and avoid unevenly overloading some compute nodes while other compute nodes are left idle.
Load balancing is the subject of research in the field of parallel computers. Two main approaches exist: static algorithms, which do not take into account the state of the different machines, and dynamic algorithms, which are usually more general and more efficient, but require exchanges of information between the different computing units, at the risk of a loss of efficiency.

    Hi all, I could do with some tips regarding fitting TRVs. My customer wants them fitted to their rads. (Don't yet know if it is to replace existing TRVs or the first-time fitting). If the current lockshields are OK (leak free and nice looking) I thought I'd leave them be. To do the job...

    Radiator Balancing

    I have balanced my own radiators, but can someone explain why there needs to be 12°C difference between the lockshield and TRV end of each radiator. How did someone come to the conclusion that 11°C or 12°C was the optimal temperature difference?
