Itanium
Itanium (; ) is a discontinued family of 64-bit computing, 64-bit Intel microprocessors that implement the Intel Itanium architecture (formerly called IA-64). The Itanium architecture originated at Hewlett-Packard (HP), and was later jointly developed by HP and Intel. Launching in June 2001, Intel initially marketed the processors for enterprise servers and high-performance computing systems. In the concept phase, engineers said "we could run circles around PowerPC...we could kill the x86". Early predictions were that IA-64 would expand to the lower-end servers, supplanting Xeon, and eventually penetrate into the personal computers, eventually to supplant Reduced instruction set computer, reduced instruction set computing (RISC) and complex instruction set computing (CISC) architectures for all general-purpose applications. When first released in 2001 after a decade of development, Itanium's performance was disappointing compared to better-established RISC and CISC processors. Em ...

Intel Itanium Architecture
IA-64 (Intel Itanium architecture) is the instruction set architecture (ISA) of the discontinued Itanium family of 64-bit Intel microprocessors. The basic ISA specification originated at Hewlett-Packard (HP), and was subsequently implemented by Intel in collaboration with HP. The first Itanium processor, List of Intel codenames, codenamed ''Merced'', was released in 2001. The Itanium architecture is based on explicit instruction-level parallelism, in which the compiler decides which instructions to execute in parallel. This contrasts with superscalar architectures, which depend on the processor to manage instruction dependencies at runtime. In all Itanium models, up to and including ''Tukwila (processor), Tukwila'', cores execute up to six instructions per cycle. In 2008, Itanium was the fourth-most deployed microprocessor architecture for enterprise information system, enterprise-class systems, behind x86-64, Power ISA, and SPARC. In 2019, Intel announced the discontinuation o ...

HPE Integrity Servers
HPE Integrity Servers is a series of server (computing), server computers produced by Hewlett Packard Enterprise (formerly Hewlett-Packard) since 2003, based on the Itanium processor. The Integrity brand name was inherited by HP from Tandem Computers via Compaq. In 2015, HP released the HP Superdome, Superdome X line of Integrity Servers based on the x86 Architecture. It is a 'small' Box holding up to 8 dual Socket Blades and supporting up to 16 processors/240 cores (when populated with Intel Xeon E7-2890 or E7-2880 Processors). General Over the years, Integrity systems have supported Windows Server, HP-UX#HP-UX 11i operating environments, HP-UX 11i, OpenVMS, NonStop (server computers), NonStop, Red Hat Enterprise Linux and SUSE Linux Enterprise Server operating systems on Integrity servers. As of 2020, the operating systems that are supported are HP-UX 11i, OpenVMS and NonStop. Early Integrity servers were based on two closely related chipsets. The zx1 chipset supported up to ...

64-bit Computing
In computer architecture, 64-bit integers, memory addresses, or other data units are those that are 64 bits wide. Also, 64-bit central processing units (CPU) and arithmetic logic units (ALU) are those that are based on processor registers, address buses, or data buses of that size. A computer that uses such a processor is a 64-bit computer. From the software perspective, 64-bit computing means the use of machine code with 64-bit virtual memory addresses. However, not all 64-bit instruction sets support full 64-bit virtual memory addresses; x86-64 and AArch64, for example, support only 48 bits of virtual address, with the remaining 16 bits of the virtual address required to be all zeros (000...) or all ones (111...), and several 64-bit instruction sets support fewer than 64 bits of physical memory address. The term ''64-bit'' also describes a generation of computers in which 64-bit processors are the norm. 64 bits is a Word (computer architecture), word size that defines ...

Hewlett-Packard
The Hewlett-Packard Company, commonly shortened to Hewlett-Packard ( ) or HP, was an American multinational information technology company. It was founded by Bill Hewlett and David Packard in 1939 in a one-car garage in Palo Alto, California, where the company would remain headquartered for the remainder of its lifetime; this HP Garage is now a designated landmark and marked with a plaque calling it the "Birthplace of 'Silicon Valley. HP developed and provided a wide variety of hardware components, as well as software and related services, to consumers, small and medium-sized businesses (small and medium-sized enterprises, SMBs), and fairly large companies, including customers in government sectors, until the company officially split into Hewlett Packard Enterprise and HP Inc. in 2015. HP initially produced a line of electronic test and measurement equipment. It won its first big contract in 1938 to provide the HP 200B, a variation of its first product, the HP 200A low-distor ...

X86-64
x86-64 (also known as x64, x86_64, AMD64, and Intel 64) is a 64-bit extension of the x86 instruction set architecture, instruction set. It was announced in 1999 and first available in the AMD Opteron family in 2003. It introduces two new operating modes: 64-bit mode and compatibility mode, along with a new four-level paging mechanism. In 64-bit mode, x86-64 supports significantly larger amounts of virtual memory and physical memory compared to its 32-bit computing, 32-bit predecessors, allowing programs to utilize more memory for data storage. The architecture expands the number of general-purpose registers from 8 to 16, all fully general-purpose, and extends their width to 64 bits. Floating-point arithmetic is supported through mandatory SSE2 instructions in 64-bit mode. While the older x87 FPU and MMX registers are still available, they are generally superseded by a set of sixteen 128-bit Processor register, vector registers (XMM registers). Each of these vector registers ...

Xeon
Xeon (; ) is a brand of x86 microprocessors designed, manufactured, and marketed by Intel, targeted at the non-consumer workstation, server, and embedded markets. It was introduced in June 1998. Xeon processors are based on the same architecture as regular desktop-grade CPUs, but have advanced features such as support for error correction code (ECC) memory, higher core counts, more PCI Express lanes, support for larger amounts of RAM, larger cache memory and extra provision for enterprise-grade reliability, availability and serviceability (RAS) features responsible for handling hardware exceptions through the Machine Check Architecture (MCA). They are often capable of safely continuing execution where a normal processor cannot due to these extra RAS features, depending on the type and severity of the machine-check exception (MCE). Some also support multi-socket systems with two, four, or eight sockets through use of the Ultra Path Interconnect (UPI) bus, which replaced ...
