I wrote a c++ program using some libraries called linbox, givaro, gmp. Now because my computer is to slow I want to run my program on a supercomputer.

I am not very familiar with networks and my programming skills are not very high. I managed to upload the data that the program uses and the c++ program itself. But of course the supercomputer has not the libraries I need and so I can not compile/link.

Can you tell me how can I proceed to get my program working or can you give me a good reference where I can learn to run c++ programs on supercomputers?

I am using the supercomputer brutuswiki.ethz.ch/brutus/Getting_started_with_Euler

  • Or at least can you give me a good reference where I can learn to run c++ programs on supercomputers. – Valentin Nov 7 '16 at 10:47
  • do you have more details about your supercomputer ? what OS/scheduler is it running ? can you package your app in a container and run it on the supercomputer ? – mazs Nov 7 '16 at 10:48
  • I found a short guide mor the supercomputer I want to use brutuswiki.ethz.ch/brutus/Getting_started_with_Euler – Valentin Nov 7 '16 at 10:54
  • I understand that there are modules that I am able to use but what should I do if the programs I need are not available there? – Valentin Nov 7 '16 at 10:55

If the hpc doesn't contain required libs, you have 2 options:

  1. Ask the admins to install the required libs
  2. Build a static executable, which contains all the libs.

If possible to go with option (2), just compile it on your machine, then upload to the hpc and run as is.

I suspect unless you have mpi/pgas as part of your code, that the performance gain would not be great - supercomputers for the most part are a cluster of "ordinary" nodes, with fast interconnects.

Being able to run concurrently is what makes an app take advantage of hpc.
