[jdmilion]

not sure if this is even the right area,

 

but what in the hell is the xeon phi? seems to be a second proccesor that can go in the pcie slot to help your cpu? will it make videos render faster? i want to knwo everything.

 

please and thanks

please and thanks

its for super computers and such, Im not sure if any consumer software supports it

[CoolaxGaming]

I would like to know this as well

[Enderman]

its a coprocessor for computing tasks

massive parallel computing performance with tons of cores (72+)

 

only special motherboards support it, not just any PCIe slot

also programs that use it need to be specially coded for compatibility, you cant just use it to render a video in after effects or something like that

[Hasleo]

in short it is "it is for massive computers and daisy chaining A LOT of CPU´s "

[jdmilion]

can i put it in my pcie hehehe

 

i have a z97 arock extreme 3

 

I WANT IT

Current Xeon Phi is also known as Knight's Corner.  It's 60-something Pentium 1 cores fabbed at 22 nm.  The next iteration coming out this year or next year is 72 Atom cores fabbed at 14nm.  I don't remember exact details, but that iteration I think will also be sold as a socketable CPU instead of just a PCI-e card.  Dunno if it's a true CPU or still just a coprossesor though.

 

Allegedly easier to work with than Cuda or OpenCL because you can start with x86 code and worry about parallelizing it straight away instead of having to do a full rewrite.

 

They cost like $4k apiece and only recently have been made available direct-to-consumers.  The initial launch was 2 years ago and you could only get one buying from HP or Dell with a business account (because Intel wanted to make sure people had a "good experience" for the launch).

so can i put it in my mobo

[jdmilion]

and will it render faster

[ZetZet]

so can i put it in my mobo

History[edit] Background[edit]
The Larrabee microarchitecture (in development since 2006^%5B7%5D) introduced very wide (512-bit) SIMD units to a x86 architecture based processor design, extended to a cache-coherentmultiprocessor system connected via a ring bus to memory; each core was capable of four-way multithreading. Due to the design being intended for GPU as well as general purpose computing the Larrabee chips also included specialised hardware for texture sampling.^{%5B8%5D%5B9%5D} The project to produce a retail GPU product directly from the Larrabee research project was terminated in May 2010.^%5B10%5D
Another contemporary Intel research project implementing x86 architecture on a many-multicore processor was the 'Single-chip Cloud Computer', (prototype introduced 2009.^%5B11%5D), a design mimicking a cloud computing computer datacentre on a single chip with multiple independent cores: the prototype design included 48 cores per chip with hardware support for selective frequency and voltage control of cores to maximize energy efficiency, and incorporated a mesh network for interchip messaging. The design lacked cache-coherent cores and focused on principles that would allow the design to scale to many more cores.^%5B12%5D
The Teraflops Research Chip (prototype unveiled 2007^%5B13%5D) is an experimental 80-core chip with two floating point units per core, implementing a 96-bit VLIW architecture instead of the x86 architecture.^%5B14%5D The project investigated intercore communication methods, per-chip power management, and achieved 1.01 TFLOPS at 3.16 GHz consuming 62 W of power.^{%5B15%5D%5B16%5D}
Knights Ferry[edit]
Intel's MIC prototype board, named Knights Ferry, incorporating a processor codenamed Aubrey Isle was announced May 31, 2010. The product was stated to be a derivative of theLarrabee project and other Intel research including the Single-chip Cloud Computer.^{%5B17%5D%5B18%5D}
The development product was offered as a PCIe card with 32 in-order cores at up to 1.2 GHz with four threads per core, 2 GB GDDR5 memory,^%5B19%5D and 8 MB coherent L2 cache (256 KB per core with 32 KB L1 cache), and a power requirement of ~300 W,^%5B19%5D built at a 45 nm process.^%5B20%5D In the Aubrey Isle core a 1,024-bit ring bus (512-bit bi-directional) connects processors to main memory.^%5B21%5D Single board performance has exceeded 750 GFLOPS.^%5B20%5D The prototype boards only support single precision floating point instructions.^%5B22%5D
Initial developers included CERN, Korea Institute of Science and Technology Information (KISTI) and Leibniz Supercomputing Centre. Hardware vendors for prototype boards included IBM, SGI, HP, Dell and others.^%5B23%5D

In June 2011, SGI announced a partnership with Intel to utilize the MIC architecture in its high performance computing products.^%5B24%5D In September 2011, it was announced that the Texas Advanced Computing Center (TACC) will use Knights Corner cards in their 10 petaFLOPS "Stampede" supercomputer, providing 8 petaFLOPS of the compute power.^%5B25%5D According to "Stampede: A Comprehensive Petascale Computing Environment" the "second generation Intel (Knights Landing) MICs will be added when they become available, increasing Stampede's aggregate peak performance to at least 15 PetaFLOPS."^%5B26%5D
On November 15, 2011, Intel showed an early silicon version of a Knights Corner processor.^{%5B27%5D%5B28%5D}
On June 5, 2012, Intel released open source software and documentation regarding Knights Corner.^%5B29%5D
In June 2012, Cray announced it would be offering 22 nm 'Knight's Corner' chips (branded as 'Xeon Phi') as a co-processor in its 'Cascade' systems.^{%5B30%5D%5B31%5D}
In June 2012, ScaleMP announced it will provide its virtualization software to allows using 'Knight's Corner' chips (branded as 'Xeon Phi') as main processor transparent extension. The virtualization software will allow 'Knight's Corner' to run legacy MMX/SSE code and access unlimited amount of (host) memory without need for code changes.^%5B32%5D
The Knight's Corner chip was announced as being rebranded as 'Xeon Phi' at the 2012 Hamburg International Supercomputing Conference.^{%5B33%5D%5B34%5D}
Tianhe-2 the world's fastest supercomputer according to the TOP500 list for June and November 2013 utilizes Xeon Phi accelerators based on Knights Corner.
Knights Landing[edit]
Code name for the second generation MIC architecture product from Intel.^%5B26%5D Intel officially first revealed details of its second generation Intel Xeon Phi products on June 17, 2013.^%5B6%5D Intel said that the next generation of Intel MIC Architecture-based products will be available in two forms, as a coprocessor or a host processor (CPU), and be manufactured using Intel's 14nmprocess technology. Knights Landing products will include integrated on-package memory for significantly higher memory bandwidth.
Knights Landing will be built using up to 72 Airmont (Atom) cores with four threads per core,^{%5B35%5D%5B36%5D} support for up to 384 GB of DDR4 RAM and 8–16 GB of stacked 3D MCDRAM (based on Micron's Hybrid_Memory_Cube). Each core will have two 512-bit vector units and will support AVX-512F (AVX3.1) SIMD instructions with Intel AVX-512 Conflict Detection Instructions (CDI), Intel AVX-512 Exponential and Reciprocal Instructions (ERI), and Intel AVX-512 Prefetch Instructions (PFI), along with Intel's full x86 instruction set except TSX.^%5B37%5D Knights Landing's TDP will range from 160 to 215 W.^{[citation needed]}
