Many Integrated Cores (MIC)
Intel Many Integrated Core Architecture or Intel MIC is a multiprocessor computer architecture developed by Intel. The Intel Many Integrated Core architecture brings an SMP programming environment onto a single chip. A co-processor, code-named Knights Corner will be the first Intel product using the Intel MIC architecture. A prototype, called Knights Ferry, was offered as a PCIe card with 32 in-order cores at up to 1.2 GHz with 4 threads per core, 2 GB GDDR5 memory, and 8 MB coherent L2 cache (256 kB per core with 32 kB L1 cache),and a power requirement of ~300 W,built at a 45 nm process.
NVIDIA Graphics Processing Units
NVIDIA gave preview of its new generation of GPU arhictecture in GTC 2012 conference, San Jose, California. The new GPU architecture is called Kepler. There are two different Kepler GPUs in development. The Kepler1 (GK104) chip, also known as , is aimed at graphics cards and Tesla GPU coprocessors, where single-precision floating point math is what matters most. Kepler2 (GK110) GPUs will be tuned for double-precision floating point math and will support more GDDR5 memory with ECC support. Kepler2 will have different packaging aimed at servers, and will cost more money than Tesla cards based on the Kepler1 units. Nvidia increased the core counts and slowed down the clock speeds, increasing the parallelism and the overall performance of GPU while significantly lowering its power draw and heat dissipation.
New features:
- New SMX (Streaming Multiprocessor eXtreme) architecture with 192 CUDA cores per multiprocesor
- The core speed is 1006MHz, with turbo boost option allowing 1058MHz
- About three times better performance per watt of power consumption
- New Hyper-Q technology that enables multiple MPI tasks to run in parallel on the GPU (up to 32 MPI tasks)
- Dynamic parallelism - GPU can adapt to data and one kernel can dynamically launch another kernel.
