Multicore processors often run far below expected performance. Finding the cause of the problem is often a lot harder than fixing it.
It is a complex and challenging task to take full advantage of today’s high performance computer architectures. Their deep memory hierarchies make it difficult to reach full performance potential, even for the most astute application programmer. Due to the wide and ever increasing memory gap, today’s fast processors often devote more than half of their time waiting for data to arrive from memory or are stalled due to a congested memory bus.
