Question

In concurrent programming, what are the differences and the common points (if any) between a race and a dead lock ? An detailed answer would be appreciated ;).

Answer 1

Have a look at Description of race conditions and deadlocks

Race Conditions

A race condition occurs when two
threads access a shared variable at
the same time. The first thread reads
the variable, and the second thread
reads the same value from the
variable. Then the first thread and
second thread perform their operations
on the value, and they race to see
which thread can write the value last
to the shared variable. The value of
the thread that writes its value last
is preserved, because the thread is
writing over the value that the
previous thread wrote.

Deadlocks

A deadlock occurs when two threads
each lock a different variable at the
same time and then try to lock the
variable that the other thread already
locked. As a result, each thread stops
executing and waits for the other
thread to release the variable.
Because each thread is holding the
variable that the other thread wants,
nothing occurs, and the threads remain
deadlocked.
