**HiPerGator consists of over 21,000 compute cores (processors). Though there are several generations of processors, all adhere to the X86_64 ABI (Application Binary Interface) and are largely software compatible. The industry trend toward more processors or "cores" per die rather than increasing clock frequencies has resulted in a fairly narrow range of processor frequencies (2 to 3 GHz) among our machines but a wide range of core counts (4 to 80). All of the processors available on HiPerGator are homogeneous in terms of instruction set and support the 64-bit extensions to the Intel X86 instruction set architecture (X86_64). This instruction set architecture is referred to as "AMD 64" by AMD and "Intel 64" by Intel. However, HiPerGator has several generations of processors from both AMD and Intel implementing what we will generically refer to as the X86_64 instruction set architecture (ISA). Currently, available processors range from older hex-core AMD Opteron 4184s to the newest 16-core AMD Opteron 6378s. In between we have several generations of Intel processors including a significant number of quad-core E5462s as well as the latest E5-2600 series. These processors range in clock speed from 2.0 GHz at the low end to 3.3 GHz at the high end. We will continue to add additional CPU resources to meet growing demand from our researchers. Older processors will be retired as they become economically inefficient to operate. The expansion of HiPerGator 2.0 consists of 30,000 cores of the latest Intel E5-2698 v3 (16 core, 2.3 GHz, 135 W) processors with 4 GB RAM per core in approximately 1,000 nodes made by Dell. The disk-less nodes have 128 GB of 2133 MHz DDR4 RAM. The total amount of RAM in HiPerGator 2.0 is 120 TeraBytes.
