Ask HN: Rent Server For A Few Days

HP will work with you on this and you can use their systems remotely. We used them at a past startup of mine and we ran on 128 cores of Itanium 2 fun, for free. If you have a customer for your code that may want to also buy HP hardware, they move quickly. You just have to sign up for their DSPP: http://h21007.www2.hp.com/portal/site/dspp/menuitem.863c3e4c...

If you really only need this for a couple of days it might be a good idea to rent, but if you'd like some real hardware you can get 24 cores and 64GB of RAM for less than $3000. If you need to test regularly it might be worth it just to buy the hardware.

use AWS EC2, I regularly rent out 15 core machine with 32GB ram for 1$ per hour, you can try getting an instance in a spot market which 20-3% cheaper (though you need to be careful).

If you need that many cores on a single machine, then I don't know how to help you -- but if you can split them up, Amazon EC2 would probably work.
