WebJan 30, 2016 · So, a modern CPU might have, say, 4 cores, each of which can execute 2 vector multiplies per clock, and each of those instructions can operate on 8 operands. So, at least in theory, it can be carrying out 4 * 2 * 8 = 64 operations per clock. Some instructions have better or worse throughput. Web16 hours ago · The class has data members a vector data_vec and pointer to a C struct handle. The C library calls are abstracted by the class interface. In the current implementation there is a void C::read () method which is called after construction by the client code to populate the vector:
