OUYA: The ‘Open’ Video Game Console for Users and Developers

OUYA Game Console

OUYA Game Console


Amazingly, OUYA, the open video game console platform raised $8,596,474 in funds on KickStarter. OUYA is based on the Android 4.0 operating system. The idea is to create a low cost console (currently $99) available for consumers that also allows developers to publish their Android games/apps to OUYA without requiring the purchase of an expensive SDK and paying licensing, retail, and publishing fees. Anyone is free to develop and publish games that can be easily downloaded and tried for free; if the user likes the app or game, he/she may purchase the full version. It’s actually quite innovative in the sense that the traditional closed living room gaming experience is now open to any developer without the traditional costs associated with developing games for known platforms like Nintendo Wii, Microsoft Xbox, or Sony Playstation.

Intel VT FlexMigration and AMD-V Extended Migration – Enabling Dynamic, Agile Data Centers

Saturday, December 3rd, 2011

VMware VMotionServer virtualization/consolidation is becoming a norm and data centers and enterprises are now looking towards the horizon at how to bring dynamic, agile, and flexible capabilities to their IT infrastructure.

What I will focus on here is one specific technology that helps meet this goal called Live Migration, the capability to move active Virtual Machines (VMs) across a pool of physical servers with no downtime. If a VM is running on a server that is reaching high utilization or where resources are becoming constrained, Live Migration can migrate the active VM to a different physical server with absolutely no downtime. Now this is what I call truly dynamic and agile! (more…)

Intel Hyper-Threading Technology

Saturday, December 3rd, 2011

Intel Core i7Intel Hyper-Threading Technology (HT Technology) enables each processing core to run multiple tasks or “threads” at the same time. Intel HT Technology also improves overall performance on threaded software by increasing processor throughput. For each physical processor core, the operating system addresses two virtual processors. For example, a processor with two cores with HT Technology will be capable of 4-way multitasking. (more…)

Symmetrical Multiprocessing in the Physical and Virtual World

Quad Core Intel Xeon E7500

Quad Core Intel Xeon E7500

The continuous shrinking of transistor size has pushed the limits of how many transistors can be placed on a single die (currently in the millions). In consequence, to utilize the increased amount of transistors, the CPU or “the core” has been replicated multiple times on the same die. Todays CPUs contain multiple cores with each core having fast L1 caches and sharing either a larger L2 or L3 cache, the bus interface, and the external die connections. For example, an Intel Xeon 7500 can support 8 sockets each with 8 cores for a total of 64 cores. Physical machines now commonly use multiple processors, but even in a multi-core processor, each core is treated as a seperate CPU. What this means is that even a multi-core CPU is taking advantage of symmetrical multiprocessing (SMP). (more…)
