Posted by on **Problem:** write a programme to calculate the integral with MPI:

Actually, the programme must be able to calculate any integral. But before writing a parallel programme, we should write a serial one to make sure it works and the algorithm is correct.

There are plenty of algorithms for calculating integrals. One of the most advanced (efficient), among non-parallel, is the method of local stack. Read more of this post

Posted by on In chemistry, engineering and earth sciences, **advection** is a transport mechanism of a substance or conserved property by a fluid due to the fluid’s bulk motion.

Mathematics describes the process of advection with the **advection equation**:

In my course on Parallel programming, I had to implement a solution to a particular advection equation, with the initial and boundary conditions defined. Read more of this post

Posted by on Hello.

I’ve spend several hours to understand how to programme in MPI and how to calculate the sum of 1/n! in parallel (it’s my task from university). (By the way, why do I have study this shit? I don’t think I will be working in the field of parallel/distributed computing.)

But finally I wrote a decent programme, which showed not bad results. And I am very excited to share with you! Read more of this post
