I don't have access to a computer cluster in my university. Is there website that accepts applications for free access to a computer cluster for scientific computing?

Further information: I am in Cuba. I need something on the order of 30 processors, about 50 GB of hard drive, for a week or so. I need to run programs written in C++ and Python.

  • $\begingroup$ I see. This is actually a very modest size -- some workstations have more than that. Clearly, you won't get this in the US because of the sanctions, but I would expect that some central or south American countries have resources many times larger and you may be able to get it done there. I'd just contact a couple of parallel computing researchers there. $\endgroup$ Oct 17, 2014 at 12:07
  • $\begingroup$ Maybe you can make a request to a South American university. For instance: nlhpc.cl $\endgroup$

For access to machines in the US, your best bet is to work with a colleague at a US institution. NSF's XSEDE machines accept users from all over the world (persons physically in Iran, Cuba, Syria, Sudan, and North Korea, excepted for sure), but Principal Investigators for allocations must be at a US institution.

  • $\begingroup$ @becko, I don't have any information about use of systems outside the US. I would look at systems in the EU, India, and China. Though, my understanding about systems in China is that using them costs money--paying the power bill at the very least. $\endgroup$

    $\begingroup$ If the system is made in the US, citizens of, e.g. Iran and Syria will not be allowed to use it -- no matter what country the computer is actually located in or owned by. US export control laws are a condition of the sale of such systems (for instance, even in Saudi Arabia). $\endgroup$ Oct 16, 2014 at 19:13
