L3 Microkernel The context for this question is the same as the previous question. You are the Lead Systems Architect for FlashTrade, a High Frequency Trading (HFT) firm. You are designing a specialized OS kernel on top of L3 microkernel to host four client trading algorithms on a single server while ensuring strict proprietary data isolation. The processor architecture you are targeting has the following features:  A 32-bit hardware address space.  Paged virtual memory system (8KB pages) with a processor register called PTBR that points to the page table in memory.  A Tagged TLB supports tagging entries with Address Space IDs (ASIDs).  A pair of hardware-enforced segment registers (base and limit) which restrict the virtual address range accessible by a process.  A virtually indexed, physically tagged processor cache.  Your system runs a shared Kernel Lib (K), which requires 512 MB, and four client protection domains. Each client runs as a user level process.  The clients use services provided by the Kernel Lib (libraries for network access, memory management, and CPU scheduling). You design the hardware address spaces for each client as follows:  Client A: Kernel Lib (512 MB) + Trading Model (2.5 GB)  Client B: Kernel Lib (512 MB) + Trading Model (2.5 GB)  Client C: Kernel Lib (512 MB) + Trading Model (1.5 GB) + Forecast Model (1.5 GB)  Client D: Kernel Lib (512 MB) + Trading Model (3 GB)   e) [2 points] Answer True/False with justification. No credit without justification. The design guarantees that the clients are protected from the Kernel. 

M.E. Lock You have designed a bus-based custom non-cache-coherent shared memory DSP (Digital Signal Processor). Each CPU in the DSP has a private cache. The hardware provides the following primitives for the interaction between the private cache of a CPU and the shared memory:  fetch(addr): Pulls the latest value from main memory into the cache  flush(addr): Pushes the value at addr in the cache to main memory; it does not evict it from the cache  hold(addr): Locks the memory bus for addr; no other core can fetch or flush this address until released  unhold(addr): Releases the lock on addr You got this generic implementation for a ticket lock algorithm and tried it on your architecture. It did not work.   struct ticket_lock {    int next_ticket;  // The next ticket number to give out     int now_serving;  // The ticket number currently allowed to enter};  void lock(struct ticket_lock *l) {    // Acquire ticket    int my_ticket = l->next_ticket++;      // Wait for turn    while (l->now_serving != my_ticket) {    // Spin    }} void unlock(struct ticket_lock *l) {    l->now_serving++;   // Release}    a) [1 point] Identify any one potential flaw in the lock function when implemented on your architecture.

Which of the following best describes Dr. Martin Luther King’s point of view when writing the Letter from Birmingham Jail?

Consider the following hypothetical scenario: The United States releases a new Indo-Pacific Strategy. It says that our goal is to advance a free and open Indo-Pacific; our ways involve building collective capacity with our allies and partners; and our means include modernizing our alliances and establishing flexible partnerships. It goes on to suggest that China will challenge this approach by using its economic, diplomatic, and technological might to coerce our allies and partners. According to lecture, is this plan an example of an effective strategy?
