A lot of people want to do very large computations which require a lot of RAM.  But above a certain threshold, the cost of memory explodes.  We had this idea but no excuse to try it.  Buy a good SSD and use it for a swap partition.  I suggest the Intel X25-M.  Make sure you have at least 1/10th of its size in RAM, i.e. 8GB of RAM for an 80GB drive, but of course more is better.  The RAM should act as a massive cache for the SSD, giving you another level in the memory hierarchy.  The latency of an SSD is about 25 microseconds, compared to 25 nanoseconds for RAM and 3 milliseconds for a hard disk.
