For computer exercises 2-4 (and for the project work later), we will use UPPNEX and SNIC-UPPMAX resources. This means that you'll need an UppMax account to access these computing resources. Please go to http://www.uppmax.uu.se/user-account-application and fill in your application for an account. Use your university email (not gmail, hotmail etc.). Choose project g2012230:BB2490_vt2013 from the Project list. Choose the Kalkyl computer system (thanks to Gokcen for pointing this out). Note: if you already have an Uppmax account, do not apply for another account.
