Solve the following python programming problem given the following code:
def check_memory_size(memLimit, num_of_threads, memoryAssignment, my_cgroups) : 
    'Check whether the desired amount of parallel benchmarks fits in the memory.
    Implemented are checks for memory limits via cgroup controller "memory" and
    memory bank restrictions via cgroup controller "cpuset",
    as well as whether the system actually has enough memory installed.
    @param memLimit: the memory limit in bytes per run
    @param num_of_threads: the number of parallel benchmark executions
    @param memoryAssignment: the allocation of memory banks to runs (if not present, all banks are assigned to all runs)
    ' 
    try : 
        def check_limit(actualLimit) : 
            if (actualLimit < memLimit) :

else : 
                if (actualLimit < (memLimit * num_of_threads)) : 
                    sys.exit ('Cgroups allow only {} bytes of memory to be used, not enough for {} benchmarks with {} bytes each. Please reduce the number of threads'.format (actualLimit, num_of_threads, memLimit)) 
if (not os.path.isdir ('/sys/devices/system/node/')) : 
            logging.debug ('System without NUMA support in Linux kernel, ignoring memory assignment.') 
            return
