Thenumpy.where()method returns a new array based on a condition applied to each element of an array. Example importnumpyasnp originalArray = np.array([1,-2,-3,4,5]) condition = originalArray <0 # For each element of originalArray,# if condition is True, use 0 as element in the ...
Array exponentiation refers to raising each element of an array to a given power. In NumPy, we can use either the**operator or thepower()function to perform the element-wise exponentiation operation. For example, importnumpyasnp array1 = np.array([1,2,3])# using the ** operatorresult1...

When the arrays are partitioned, cuPyNumeric launches tasks on the GPUs. The task on each GPU performs element-wise additions on the tiles ofcenterandnorthassigned to that GPU. Figure 2 shows an example parallelization of the expression with four tasks using 2 x 2 partitions ofcenterandnorth....
