DPUCAHX8H can be
deployed with one or two cores on the Alveo
U50/U50LV card or with one, two, or three cores on the Alveo U280/U55C card. They are named core0, core1, and core2. You can
locate core0 on SLR0, core1 on SLR1, and core2 on SLR2. To get the best performance of
HBM, DPU AXI ports should be connected with the following rules.
