comment Variable scope similar to other languages
@Szabolcs: Just like the other languages that I mentioned, if a variable/function is not defined in the local scope, the global version is used. If it is defined both locally and globally, the local version is used.

comment Variable scope similar to other languages
@Kuba: 'locally' means in the local scope. I updated the question and added a new variable. I hope it is clear now. Actually, I want to define all the variables in the local scope and only share the ones which are specified in the list (the first parameter of Scope) with the global scope.

comment How to monitor the communication between parallel kernels
If you want to monitor the communication between kernels running on the same machine and you are using Windows, this link might be useful stackoverflow.com/questions/8496388/…

comment How to monitor the communication between parallel kernels
If the kernels are running on different machines, something like wireshark.org might be helpful. If the data is not encrypted, you can even see the content of the packets. Otherwise, you would be able to monitor the size/number of the packets.

comment Baffling increase in runtime
@KeshavSaharia: Most of operating systems first try to increase the fan speed when the temperature of the CPU goes high. But if the fan speed reaches the limit and the temperature is still higher than desired, the OS inserts some idle time slots in between the processes executions to cool down the CPU. In the second phase you may see a drastic slow down in execution speed of the programs, because the CPU power is not 100% used.

comment Baffling increase in runtime
@KeshavSaharia: Do you have a 32 bit machine or OS? This may be the cause based on Pinguin's observation.

comment Baffling increase in runtime
@KeshavSaharia: Your observation is system dependent and does not produce the same result on my machine. On my machine, the increase in runtime is very close to a linear function which looks reasonable. There are many different factors that may affect the running time. Specially, in multitask operating systems, timing is not so accurate. You need to execute your test for a reasonable number of runs and take the average to get acceptable numbers. The temperature of the CPU may affect the runtime as well. Another factor is whether the algorithm is run on GPU or on CPU.
