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.....
