Yes it can be done. You will need to enable ramdisk support in your kernel. (Set the ramdisk size there to something big enough to run your program.) Then put something like this in your /etc/fstab: /dev/ram /ram minix user,noauto 0 0 (On my machine, /dev/ram is a symlink to /dev/ram1, and /ram is just a mount point I created: mkdir /ram) I occasionally use a 64MB ramdisk, for recording music (actually for testing whether the HDD is a bottleneck in music recording). To use the ramdisk, I say: mkfs.minix /dev/ram 65536 mount /ram Can't remember why I used the minix filesystem, you can probably use anything you like (e.g. ext2fs). I don't know how the ramdisk memory is managed though, anybody else know? I'm not sure there is anything protecting that memory from being overwritten by other applications, though you'd think there would be. Hmm. Anyway, try it. Also I wonder if putting more memory in your machine would prevent your program from being un-cached. -chris
