[Numpy-discussion] Memory efficient equality test for arrays

Is there a numpy call to test if two large arrays (say 1 Gbyte each) are 
equal (same shape and elements) without creating another large array of 
booleans as happens with "a == b", numpy.equal(a,b), or 

I want a memory efficient and fast comparison.
