Hardware Tuning

Reduce cross-chip data overheads.

Install the NVMe SSDs and NIC into the same riser card.

Populate one DIMM Per Channel (1DPC) to maximize the memory performance. That is, populate the DIMM 0 slot of each channel.

Preferentially populate DIMM 0 slots (DIMM 000, 010, 020, 030, 040, 050, 100, 110, 120, 130, 140, and 150). Of the three digits in a DIMM slot number, the first digit indicates the CPU, the second digit indicates the DIMM channel, and the third digit indicates the DIMM. Populate the DIMM slots whose third digit is 0 in ascending order.
