Dell Dumping Itanium
njcoder writes "In a PC World article it is disclosed and confirmed by Intel that Dell is dropping support for Itanium processors. 'After Advanced Micro Devices demonstrated that 64-bit extensions to the x86 instruction set offered a smoother transition to 64-bit computing, Intel released a version of Xeon with similar technology, and Dell now offers 64-bit Xeon processors across its product line.'" More from the article: "The chip maker has since backed off its original statements about Itanium and is now promoting the chip as a high-performance replacement for reduced instruction set computing (RISC) processors in Unix servers from companies such as Sun Microsystems and IBM. Hewlett-Packard, a co-designer of the processor, has embraced Itanium as the processor of choice for its high-end servers. Fujitsu. and NEC are also among the system vendors that sell servers with the processor." The story is also being reported at Ars Technica.
SGI uses Itanium for their Altix line of products that run Linux. They need Itanuim for its ability to handle hundreds of processors in one system with cc:NUMA, and its huge physical address space for their customers who need several terabytes of RAM in one system.
