示例1: generate_matrix

# 需要导入模块: from field import Field [as 别名]
# 或者: from field.Field import multiply [as 别名]
def generate_matrix(q, number_processes = 35):
    field = Field(q)
    two_powers = [2 ** (q - i) for i in xrange(q + 1)]
    with Manager() as manager:
        A = manager.dict()  # where we store the row integers
        amount = lambda : len(A) # I use this to print out how many rows we have generated periodically
        
        def append(x):
            if x in A:
                return 0
            A[x] = True
            return 1
        
        #append = lambda x : A.__setitem__(x, True)
        is_new = lambda x : not A.__contains__(x)   # to avoid duplicate entries
        
        # we don't need the a = 0, b = q - 1 case because it requires setting the 0th column (0 * (q-1)) which has already been chosen
        a = q - 1
        
        # generate all the numerators quickly
        numerators = [[field.add(field.multiply(a, t), c) for t in field.trace()] for c in field]
        
        bs = range(q - 3) + [q - 1]   # all the b values we need
        
        _distribute(lambda bs : _make_and_start_process(bs, a, field, numerators, append, is_new, two_powers, amount), bs, number_processes)
        # start all the processes and then wait for them to finish
        
        # the keys of the dictionary represent the row integers for the problem
        return A.keys()
