- Explain the concept of deadlock in multithreading. How does it occur, and what are some strategies for avoiding or resolving deadlock situations in concurrent programs?List the 4 conditions that can cause a deadlock for concurrent processes P1 and P2. (short answer is ok)Can you explain what "memory leaks" are in the context of dynamic memory allocation?
- Both symmetric and asymmetric forms of multiprocessing exist. Can you tell me the pros and cons of utilizing several CPUs for the same task?Please let me know if these are true or false! In multiprocessors with a shared physical main memory, an access to a word of main memory always takes about the same amount of time no matter which word is being accessed and by which processor: T/F? When reading data from a magnetic disk, the rotational latency increases linearly with the size of the request: T/F? SSD is faster to access than magnetic disk, but slower than DRAM main memory: T/F? The primary purpose of RAID is for data backups: T/F? Typically, data parallelism offers greater opportunities for achieving highly-parallel execution than does functional parallelism: T/F? In MIPS systems, one way to implement locks is with the MIPS test-and-set machine language instruction: T/F?How does the concept of "garbage collection" work in memory management within computing systems?
- When it comes to multiprocessing, you have the option of using either a symmetric or an asymmetric approach. What are the advantages of using several processors in a single application, as well as the disadvantages of doing so, and how may they be avoided?If you want to compare the time it takes to make a cake to the time it takes to calculate three iterations of a loop on a parallel computer, think about making a cake. Locate and describe instances of data-level and task-level parallelism in the baking process.One reason the assembler's object files are not executable is that each object file is created independently of the others in the programme. As a result, they are unaware of the existence of other object files in the programme; linking object files is required to produce an executable file. Can an object file be run if it contains only one source file and does not include any library files? What are your reasons for or against?
