Hi Alexander, i only have one 8GB computer which is a notebook, but it can not install ubuntu (dual boot with window)after download 64 bit ubuntu in virtual box and assign 5018GB ram and then compile gap 64 bit got error after only tuples number instead of tuples a list of matrix, then i type return; and wait for a long time, still not have response. i guess that i either buy a new computer or use aws.amazon can gap system install in aws.amazon after sign up free trial i haven't signed up yet since i do not know whether it auto deduct my money after free trial period is the linux in amazon that can be used to install gap system?
