slaved

project components:

• slaved daemon which is meant to be run on slaves instanced, listening for requests.
• master_middlewares.a to be compiled with the master program, providing functions to interact with the slaved daemons, basically: init_cluster(), queue_task() and is_done().

implementation details:

slaved

slaved is just a requests dispatcher in a sense that it receive requests and calls a function based on request's type (i.g. TYPE_REQ_INIT, TYPE_REQ_COMPUTATION, TYPE_REQ_FINISH, TYPE_REQ_ABORT).

master_middlewares.a

master_middlewares.a is where all the stuff happens, parsing configuration file, connecting slaves and firing a slave_routine() for every slave and running a load balancer, basically.

the whole interaction can be summed (not very well) in this flow chart:

what I learned (from what I suffered)?

• threads are cool.
• to put a mutex in everything.
• to dequeue a node before enqueuing it to some other queue.
