Cedar has a total of 27,696 CPU cores for computation, and 584 GPU devices. Total theoretical peak double precision performance is 936 teraflops for CPUs, plus 2,744 for GPUs, yielding over 3.6 petaflops of theoretical peak double precision performance. 22 fully connected "islands" of 32 base or large nodes each have 1024 cores in a fully non-blocking topology, with each island designed to yield over 30 teraflops of double-precision performance (measured with high performance LINPACK). There is a 2:1 blocking factor between the 1024 core islands. | Cedar has a total of 27,696 CPU cores for computation, and 584 GPU devices.
