No, you can't tell how long it's going to take or how much memory it'll use. 
You can only tell if it's going to take more than X time or more than Y 
memory.  You do that by running it until it either halts or exceeds that 
limit. (And you can tell if you got in a loop using only a fixed amount of 
memory, so that's not hit by the halting problem.)

That's different from figuring out the minimum X time to doesn't take longer 
than, for example.
