According to this question,

When you execute something synchronously, you wait for it to finish before moving on to another task

if this is the case, does multi-threaded synchronous execution means that other threads,say B,C,.. are waiting (blocked) for thread A to finish? if yes, then how can it differ from with single-threaded synchronous execution? what's the benefit?

EDIT:

In other words, does Multi-threaded Synchronous operation means :

thread A -> |----A-----|   
                        \  
thread B ------------>   ->|-----B-----------|   
                                              \   
thread C ---------------------------------->   ->|-------C------|

or it can be

thread A -> |----A-----|   
                         
thread B ->|-----B-----------|   
                                               
thread C ->|-------C------|

thanks.

No, other threads will just continue running. Only your current thread is blocked till the execution is finished. Normally you do this when you need the output for your next step.

  • ,if other threads continue running, can't we say that they are independent of thread A ,and then it would be asynchronous operations? – user3723486 Aug 19 '16 at 10:50
