mem_usage consists of the following fields:

for_lu (float)
     The amount of space used in bytes for the L\U data structures.
total (float)
     The amount of space needed in bytes to perform factorization.
expansions (int)
     Number of memory expansions during the LU factorization.

void duser_free_dist	(	int_t	bytes,
		int_t	which_end
	)

duser_malloc_dist()

void * duser_malloc_dist	(	int_t	bytes,
		int_t	which_end
	)
