Intel Larrabee @ SIGGRAPH 2008
http://www.siggraph.org/s2008/attendees/program/item/?type=papers&id=34
ovo mi zvuci kao do sada najpreciznija definicija Larrabija:
"Larrabee a many-core hardware architecture, a new software rendering pipeline, a many-core programming model, and performance analysis for several applications. Larrabee uses multiple in-order x86 CPU cores that are augmented by a wide vector processor unit, as well as fixed-function co-processors. This provides dramatically higher performance per watt and per unit of area than out-of-order CPUs on highly parallel workloads and greatly increases the flexibility and programmability of the architecture as compared to standard GPUs"
Jasno je da Larrabee nema apsolutno nikakve veze sa onim na sta lice moderni GPU-ovi. narocito je indikativna ova "sitnica": "as well as fixed-function co-processors"... nije mi jasno kako se to uklapa u svet danasnjih veoma programabilnih GPU-ova i standardizovanih API-a koji podrzavaju tu programabilnost!?
Ocigledno nikako, jerbo Intel za Larrabee ima novi API!!
"A new programming language for general-purpose computation on the GPU. A BSGP program looks much the same as a sequential C program. Programmers need to supply only a bare minimum of extra information to describe parallel processing on GPUs. As a result, BSGP programs are easy to read, write, and maintain. And the ease of programming does not come at a performance cost."
istini za volju ovo i nije graficki API, vec direktna konkurencija CUDA-i:
"Benchmark analysis shows that BSGP programs achieve performance that is similar to or better than well-optimized CUDA programs, while source-code complexity and programming time are significantly reduced."
Ajd da sacekamo i taj avgust ne bi li mozda dobili jos razjasnjenja, ali mi Larrabee sve manje izgleda kao akcelerator za igrice i grafiku, a sve vise kao GPGPU resenje na Intelov nacin. Cini mi se da i NVIDIA tako posmatra Larrabee, pa bas iz tog razloga u promociji GT200 daje izuzetan akcent na GPGPU pricu i CUDA-u!
Mozda genuine moze malo vise informacija na tu temu da nam da?
