Which technology is cited as providing the "universal addressability" required to track an estimated 100 trillion static or moving objects in the Internet of Things (IoT)?
RFID and GPS sensors
IPv6 protocol with 2^128 IP addresses
Cyber-Physical Systems (CPS)
100 Gigabit Ethernet (100 GE)
Cyber-Physical Systems (CPS) are defined by the integration of which "3C" technologies?
Clusters, Clouds, and Connectivity
Computation, Communication, and Control
Convergence, Concurrency, and CMOS
Capacitance, Circuits, and Cooling
Why has the clock rate of modern processors largely limited at approximately 5 GHz?
Failure of Moore's Law
Power and heat constraints in CMOS chip technology
Lack of Instruction-Level Parallelism (ILP)
The transition from RISC to x-86 architectures
In the context of multithreading micro-architectures, which pattern allows for the simultaneous scheduling of instructions from different threads in the same cycle?
Fine-grain Multithreaded
Coarse-grain Multithreaded
SMT (Simultaneous Multithreaded)
Dual-core CMP
5. How does the architectural optimization of a GPU differ from that of a CPU?
CPUs are optimized for throughput, while GPUs are optimized for latency.
CPUs are optimized for latency (caches), while GPUs are optimized for throughput.
CPUs use "thin" cores, while GPUs use "fat" cores.
GPUs focus on ILP, while CPUs focus exclusively on DLP.
In the NVIDIA Fermi GPU architecture, what is a "warp"?
A single CUDA core
A streaming multiprocessor (SM)
A group of 32 threads scheduled together
A type of off-chip DRAM
What is the "Memory Wall" problem described in the sources?
The physical limit of how many DRAM chips can fit on a motherboard
The worsening gap between fast processor speeds and slower memory access times
The 300,000-cycle write limit of Solid-State Drives (SSDs)
The inability of 32-bit systems to address more than 4 GB of RAM
According to the technology trends, how does the growth of network bandwidth compare to Moore’s Law for CPU speed?
Network bandwidth grows slower than CPU speed.
Both grow at exactly the same rate (doubling every 18 months).
Network performance increases by 2x per year, which is faster than Moore's Law
Network growth has reached a limit, unlike CPU growth.
Which type of Virtual Machine (VM) architecture involves a VMM (Hypervisor) running in privileged mode directly on the hardware?
Hosted VM
Native VM (Bare-metal)
Dual-mode VM
Physical Machine
What is the power efficiency target required to achieve an Exascale computing system?
1 Gflops/watt
5 Gflops/watt
200 pJ/instruction
60 Gflops/watt per core
