Hello, I've got a script on genomic data that uses about 17 GB of RAM, most of it to a hash. I have tried "undef" on the biggest hashes but this does not free memory to the OS. The computer has 8 GB of RAM. How can I get the script to write the excess memory (say, any RAM over 6.5 GB) to disk instead of RAM, while the program is executing, deleting the excess memory hash afterward? thanks, -DEC
