Shared Variables

#pragma MP taskloop shared (list_of_shared_variables) specifies all the variables that should be treated as shared variables for this loop. All other variables used in the loop that are not explicitly specified as private, readonly, storeback or reduction variables, will be either shared or private as defined by the default scoping rules.

A shared variable is a variable whose current value is accessible by all processors processing iterations of a for loop. The value assigned to a shared variable by one processor working on iterations of a loop may be seen by other processors working on other iterations of the loop.
