The product's most recent version, "Superdome 2," was released in 2010 supporting 2 to 32 sockets (up to 128 cores) and 4 TB of memory. The Superdome used PA-RISC processors when it debuted in 2000. Since 2002, a second version of the machine based on Itanium 2 processors has been marketed as the HP Integrity Superdome.
With GCC, which does not support the aforementioned pragma, [11] this can be globally controlled by the -ffp-contract command line option. [12] The fused multiply–add operation was introduced as "multiply–add fused" in the IBM POWER1 (1990) processor, [13] but has been added to numerous other processors since then: HP PA-8000 (1996) and above
HP announced Superdome 2 in April 2010, offering resiliency improvements, a modular, bladed design, common components and crossbar fabric that routes transactions to the optimal pathway between blades and I/O. [6] Superdome 2 addresses requirements for high-performance computing by providing flexible scalability and fault tolerance necessary ...
C2 (often known as Stop-Clock) is a state where the processor maintains all software-visible state, but may take longer to wake up. This processor state is optional. C3 (often known as Sleep) is a state where the processor does not need to keep its cache coherent, but maintains other state. Some processors have variations on the C3 state (Deep ...
The PA-8000 is a four-way superscalar microprocessor that executes instructions out-of-order and speculatively. [1] [4] These features were not found in previous PA-RISC implementations, making the PA-8000 the first PA-RISC CPU to break the tradition of using simple microarchitectures and high-clock rate implementation to attain performance.

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.
HP planned to use Spectrum to move all of their non-PC compatible machines to a single RISC CPU family. In early 1982, work on the Precision Architecture began at HP Laboratories, defining the instruction set and virtual memory system. Development of the first TTL implementation started in April 1983. With simulation of the processor having ...
