Questions tagged [intel]

For issues related to Intel semiconductor chips and assemblies, Intel architectural features and ISA extensions, and Intel chips micro-architecture.

Intel Corporation is an American multinational semiconductor chip maker corporation headquartered in Santa Clara, California, United States. Intel is the inventor of the x86 processor architecture and makes central processing units, motherboard chipsets, graphic processing units, network interface controllers and much more devices related to communications and computing.

In addition to their hardware offerings Intel also produces a variety of software including compilers, libraries for mathematical computation(Intel MKL), threading(OpenMP, Intel Performance Primatives, Threading Building Blocks), parallel communication(MPI,OFED/True Scale Infiniband Stack) and several other products included in the Intel Parallel Studio toolkit. In addition to these offerings which are widely used in HPC Intel also produces software for datacenter management and is one of the most prolific contributors to the Linux kernel.

This tag should be used for questions about Intel hardware and software.

The x86 and/or x86-64 tags are better choices for questions about assembly programming for the architecture, rather than things like performance tuning specifically for Intel's implementation of x86.
