سلام دوستان با اجازه اساتيد اين بخش من باز ميكنم تا بحث و خبر مربوط به كد رمز يعني Larrabee GPU قرار دهيم.
خوب كمي از بحث خودم مي برم جلو :
اول بايد 2 چيز مشخص كنيم يهني فعلا معلوم نيست اينتل اين GPU به چه شكلي ميخواد عرضه كنه يعني اينكه ايا اين GPU ميخواد:
1. رو برد جدا گانه بزنه
يا
2.ميخواد چند گرافيك مجتمع بر روي پردازنده خودش قرار بده كه بدون شك با همين اسم هم عرضه ميشه
البته شايدم بخواهد هر دو به انجام برسون كه به نظر من همين طور و اين ميشه گفت 100% با توجه به مشخصات كه تا الان داده شده :1. (26):
خوب براي اينكه اين موضوع بفهميم بايد ايستاد ببينم تا سال 2008 كه مدل سمپل اين كارت به نمايش گذاشته ميشه ديد
خوب حال ميخواهيم به بررسي قسمت هاي تشكيل شده ان بپردازيم
اول بگم كه واقعا با يك نسل كاملا جديد graphics رو به رو هستيم واقعا يك مولتي GPU ميشه ناميد كه داراي 16 core كه هر كدام قابليت هاي گوناگوني ميدن
Larrabee is a GPU, Physics
از اين متن ميشه فهميد كه يك پردازنده فيزيكي هم همراهش كه اين من فرض بر اين ميكنم كه يكي از 16 core باشه يعني 16 قابليت ها وهيمن طور از GPGPU هم پشتيباني به عمل مياد كه كار براي برنامه نويسان وطراحان گرافيك راحت ميكنه يعني ديگر نياز نيست مداوم از كدها API استفاده نمايند (تا اونجايي كه مدونم)
Intel is preparing to re-enter the GPU market with a bang. In secret underground facilities, Intel is developing a next generation graphics architecture called Larrabee. It may be based on x86 but with "mini-cores" that have the "smart" parts of CPU cores stripped out and extra vector units added. The cores just need to stream data, mostly vector data. It'll have many cores, more than CPUs. Each core will process multiple threads simultaneously.
Many Cores (16+)
Hyper-Threading (4 Threads Per Core)
1024-bit or 2048-bit Bidirectional Internal Ring Bus
Large Cache
GDDR5 Memory
PCI Express 2.0
Release Date: Q4 2008 or Q1 2009
The architecture will later (2010+) be integrated in some Intel CPUs.
پشتيباني هاي ان :
اول از همه كارت از دايركس 11 همچين مدل هاي اوليش از 10.1 هم پشتيباني داره
PCI Express 2-3 پشتيباني خواهد داشت البته مدل هاي اوليه از 2 وبه بعد 3
سرعت باورنكردي 1.7-2.5 GHz را براي Core خواهد داشت و به همراه 16-24 texture sampling units كه در سرعت انواع معادلات گرافيك تاثير باورنكردني خواهد داشت
در مدل هاي 45 و همچنين 32 نانومتري عرضه ميشود كه مقدار TDP 150W خواهند رساند البته مدل هاي فوق High-End ان
و اخر هم بگم كه يك مدل هم براي كنسل ها هم توليد خواهد شد
اين متن ها هم حتما بخوانيد خيلي مفيد هستن :
At IDF it was confirmed that Larrabee will be a discrete GPU for "high-end" graphics. The processor should also handle physics acceleration. Expect the Havok physics engine (now owned by Intel) to be optimized for Larrabee.
The plan is to have 45nm Larrabee in 2009, a 32nm update in 2010 with more cores, and a new GPU architecture in 2011.
Larrabee is not only for graphics/visualization.
منظورش اين كه Larrabee تنها يك گرافيك و تصويري نيست
كه در ادامه اين گفته :
Gelsinger said that Intel has begun planning products based on a highly parallel, IA-based programmable architecture codenamed "Larrabee." It will be easily programmable using many existing software tools, and designed to scale to trillions of floating point operations per second (Teraflops) of performance. The Larrabee architecture will include enhancements to accelerate applications such as scientific computing, recognition, mining, synthesis, visualization, financial analytics and health applications.

Larrabee: 16 Cores, 2GHz, 150W, and more
16 Cores : فكر كنم منظور اين كه 16 پردازش مي توانه انجام بده كه مربوط به همين قابليت هايي كه در بالا گفتم هست يعني 16 قابليت نه فقط گرافيك
متن اصلي :
It is amazing how much information is out there in the wild, when you know where to look. TG Daily has just published an article partially based on a presentation they were tipped off about, and which was uploaded on the 26th of April. It reveals a substantial amount of new information, which we will not focus on analysing right now, so we do encourage you to read it for yourself.
Page 1 discusses the possibility that Larrabee is a joint effort between NVIDIA and Intel, which we find unlikely, and is possibly just a misinterpretation of the recently announced patent licensing agreement between the two companies. Page 2 is much more interesting however, as they link to the presentation above and also uncover the hidden Larrabee PCB diagram on slide 16.
We would tend not to agree with most of the analysis and speculation provided by TG Daily, but it's still worth a good read along with the presentation, which we are very glad they uncovered. Especially interesting are slides 16, 17, 19, 24 and 31. That last one includes some very interesting and previously unknown information on Intel's upcoming Gesher CPU architecture (aka Sandy Bridge), which is aimed at the 32nm node in the 2010 timeframe. Larrabee, on the other hand, will presumably be manufactured on Intel's 45nm process but sport a larger die size.
