Question

For each of the following characteristics, write an adequately matching acronym or a single/couple of word(s):

1. A parallel programming model derives concurrency from a set of communicating sequential processes each with a separate address space ________

2. A parallel library call which needs to be called by all executing threads or processes ____________

3. A parallel architecture in which each node has a separate address space ________

4. An execution model in which each process gets and executes a separate copy of the same program _____________

5. An operation by a thread or a process and for which the invoking thread/process does not wait for the completion of the operation ____________

6. A parallel operation that must be executed by all processes (or threads) _ ______________

7. A synchronization mechanism in which all processes or threads must reach the same point in the code before any of them proceeds any further ____________

8. A parallel architecture in which all processor nodes physically share one memory subsystem __________________

9. A parallel programming model in which the programmer is given the illusion that he/she has a shared memory system __ __________

10. A parallel architecture in which each processor has a local memory that is shared with the rest of the processors __________

11. A parallel programming model in which the programmer is given the illusion that he/she has a distributed shared memory system. __________

12. A synchronization mechanism which is used to make sure that a critical code section is only executed by a single thread at a time ____________

13. A programming model which can be described as one-sided ______________

14. A parallel computer architecture in which all processing elements perform the same instruction in the same time _____________

15. A parallel computer architecture in which synchronization is done via software ____________

16. An inter-process (or inter-thread) communication call at which the process will stop till the operation is completed by all executing processes_______________

17. A parallel architecture in which synchronization is done in the hardware ______________

Explanation / Answer

process algebra multiprocess runs on separate node process id Graphical User Interface Parallel Processing Bounded buffer problems Memory nodes shared main memory and cache powerful process and wide memory peer to peer systems synchronized block point to point and collective increases efficiency serial computation communication among lightweight and heavyweight processes. taxamony
