So, I will "divide" the grid to different threads, which will work on it for single iteration. After each iteration, all threads should wait since next iteration depends on previous iteration.

I suggest looking at std.parallelism since it's designed for this kind of thing.  That aside, all traditional synchronization methods are in core.sync.  The equivalent of "sync" in Cylk would be core.sync.barrier.
