Accelerate software running in linux

view story

http://stackoverflow.com – I need to test a software stability for one month under linux. Obviously, one month is too long . I am wondering, is there a tool that can accelerate this process, like if using this tool for 30 hours just like running this machine for one month (30 days)? Please be notice this tool should support linux. Thanks any reply in advance. Li (HowTos)
