Pоtpоurri_4 Pоtpourri 4. [2 points] Consider аn аpplicаtion running on a Shared Memory Multiprocessor. Consider threads T1 and T2 of a process running on two distinct cores. Both threads attempt to open distinct files concurrently. The resulting system calls lead to kernel code executing on each core and file descriptor table being loaded on the memory local to each core. The file descriptor table will have to remain coherent between both cores, which is expensive. Does the Corey Operating System provide a solution to this problem? Explain succinctly.
