Figure 5

Relative change in instructions retired (top row), clockticks per instruction retired (CPI, middle), and clockticks (bottom) during spike delivery for P2RB (including SRR as in Figure 4), and noSSG as a function of the number of MPI processes. Raw data for all three quantities was obtained by VTune (Section 3.4.1). Left column DEEP-EST CM and right column JURECA CM: linear-log representation for number of MPI processes M∈{2; 4; 8; 16; 32; 64; 90} and M∈{2; 4; 8; 16; 32; 64;  128; 256; 512}, respectively. Black dotted line at zero percent (ORI, Section 2.3) indicates the performance of the original code. Weak scaling of benchmark network model as in Figure 4.
