Simply reformat it as a swap partition, then add it to your swap space. However note that this may decrease performance, rather than increase it, as write speeds on SD cards are very slow.

See the section"How do I add more swap?"

The "swap" solution will not help you as Ready Boost. Swap is used for virtual memory, and not for HDD buffer.
What part of the job do you want to improve:
   simulate more RAM: as said mycae, it's not obvious. With 2GB, your program should be whole on RAM
   accelerate disk access in reading: you'll have to copy first input file on SD card
   accelerate disk access on writing: same issue
In both last cases, as files are accessed sequentially, you probably gain nothing
You could gain on intermediate files. For this, I suppose you have to configure your software.
SD card is efficient with small and dispersed data.
You should measure actual performance of SD card before trying to optimize.

Can you help with this problem?
