A new easy way for installing and trying out DB2 with BLU Acceleration is available: The DB2 BLU Acceleration Kit for Trial. The kit is a software image that automatically installs a Linux operating system, DB2 and some tools into an x86_64 machine - the machine can be real HW or a virtual machine. The only input needed is for passwords, then the kit installs everything starting with the OS.
