Introduction to MPI - Part I

[@destigmatizemath]

Fantastic! All of the other tutorials for MPI that I have found have forced me at full speed into a roadblock. This one has been very helpful and informative.

I was looking for this kind of tutorial for long time. It helps a lot, thanks!

you probably dont give a shit but if you guys are stoned like me during the covid times you can watch pretty much all of the latest movies and series on instaflixxer. Have been streaming with my girlfriend these days :)

@Robert Genesis Yea, have been watching on InstaFlixxer for years myself =)

good explanation. however, cannot find mpirun.exe

[@preneyp]

In order to use MPI on your own computer it must be installed. MPI is installed on our (Compute Canada's) clusters. (Submit a ticket if you need assistance with such.) If you also want to do some development/testing on your own computers, if using Windows, you are probably best to install "Windows Subsystem for Linux" or "Cygwin" and after one of those is installed, install OpenMPI and GCC within them so you can write, compile, and run MPI programs.

[@electrotsmishar]

@@preneyp Thanks for your reply. I was able to implement some MPI applications successfully using MSMPI natively on Windows and enjoying it. However, cygwin's openMPI always gives me tons of errors. I think it cannot find the files for some reason. The compilation succeeds but not execution

[@preneyp]

@@electrotsmishar If your code compiles and links without any errors that is good --but you will need to figure out why it is not running properly. Take note (i.e., write down) what is/are the errors you are encountering so this can be shared with appropriate persons at the institutions/schools you are involved with. It might be a configuration issue and/or it could be something in your code. (Using this message forum is not a suitable medium for figuring such things out. The resolution might be simple --or it might not be.) :-)

[@electrotsmishar]

@@preneyp Okay, thank you. Actually, I'm happy with Microsoft MPI. So, I don't think I have a good reason to use openMPI right now. Don't belong to an institution as well. That's it. It was just for my personal project
