By default, it's 32MB but you can change that via /proc/sys/kernel/shmmax. There is no a priori limit for how big a value you can install there, but on IA-64 Linux you'll be limited to what fits in a single region. With 16KB pages, that would be 16TB.

Normally this is set to 32MB, but you can change it in file include/linux/shm.h (parameter SHMMAX). There is also /proc interface for shared memory parameters, but I don't think that you can use this interface to modify the parameters.....
