What does Itanium-based systems mean?

What does Itanium-based systems mean?

Itanium (/aɪˈteɪniəm/ eye-TAY-nee-əm) is a discontinued family of 64-bit Intel microprocessors that implement the Intel Itanium architecture (formerly called IA-64). Itanium-based systems were produced by HP/Hewlett Packard Enterprise (HPE) (the HPE Integrity Servers line) and several other manufacturers.

Why was Itanium discontinued?

Put simply, Itanium failed in part because Intel pushed a task into software that software compilers aren’t capable of addressing all that effectively. More details on this issue are available here.

What is Itanium ABI?

In this document, we specify the Application Binary Interface (ABI) for C++ programs: that is, the object code interfaces between different user-provided C++ program fragments and between those fragments and the implementation-provided runtime and libraries.

What happened to HP UX?

Support for HPE’s Itanium-powered Integrity servers, and HP-UX 11i v3, will come to an end on December 31, 2025, though it’s unclear exactly when new sales will be wrapped up.

Is IA64 same as x64?

IA64 – or Intel Itanium – processors run 64-bit natively and offer 32-bit emulation, but you cannot install 32-bit Windows on it. x64 is the term Microsoft uses to collectively refer to processors that run both 32- and 64-bit code natively without emulation – both AMD64 and EM64T.

What is Itanium C++?

The Itanium C++ ABI is an ABI for C++. Accordingly, it is used as the standard C++ ABI for many major operating systems on all major architectures, and is implemented in many major C++ compilers, including GCC and Clang.

What is the C++ ABI?

As C++ evolved over the years, the Application Binary Interface (ABI) used by a compiler often needed changes to support new or evolving language features. Consequently, programmers were expected to recompile all their binaries with every new compiler release.

What is Intel Itanium?

Intel Itanium is a 64-bit processor family based on IA-64 Instruction Set Architecture (ISA). In a joint venture with Hewlett-Packard (HP), Intel decided to develop a new type of processor that would better suit the modern workloads and implement some new ideas in the processor architecture realm.

How many Itanium processors are in a computer?

A typical system uses eight or more Itanium processors. By 2012, only a few manufacturers offered Itanium systems, including HP, Bull, NEC, Inspur and Huawei. In addition, Intel offered a chassis that could be used by system integrators to build Itanium systems.

Who makes Itanium microprocessors?

Itanium-based systems were produced by HP/ Hewlett Packard Enterprise (HPE) (the HPE Integrity Servers line) and several other manufacturers. In 2008, Itanium was the fourth-most deployed microprocessor architecture for enterprise-class systems, behind x86-64, Power ISA, and SPARC.

What is a Tukwila Itanium processor?

The “Tukwila” Itanium processor model had been designed to share a common chipset with the Intel Xeon processor EX (Intel’s Xeon processor designed for four processor and larger servers). The goal was to streamline system development and reduce costs for server OEMs, many of which develop both Itanium- and Xeon-based servers.
