2019-05-01 KENNETH 0

AMD 기반 Amazon EC2 T3a 인스턴스 정식 출시 작년에 약속했던, AMD EPYC 기반 T3a 인스턴스를 정식 출시했습니다. 최근 발표한 M5ad 및 R5ad 인스턴스와 마찬가지로, T3a 인스턴스는 AWS Nitro System에 구축되었으며, 이를 통해 비용과 성능을 기준으로 혼합된 인스턴스의 균형을 맞출 수 있습니다. T3a 인스턴스 소개 이 인스턴스는 버스트 가능한 경제적인 성능을 제공하며, 높은 컴퓨팅 성능을 지속할 필요는 없지만, 사용량에서 일시적으로 스파이크가 발생하는 워크로드에 매우 적합합니다. 넉넉한 수준의 기본 처리 능력이 보장되고, 더 많은 처리 능력이 필요한 경우 얼마든지 오랫동안 최대 코어 성능으로 투명하게 확장할 수 있는 기능을 제공합니다. T3 및 T3a에서 공통된 버스트 가능한 컴퓨팅 모델에 대해 자세히 알아보려면 새로운 T3 인스턴스 – 버스트 가능하고 경제적인 성능을 참조하십시오. 오늘 T3a 인스턴스는 미국 동부(버지니아 북부), 미국 서부(오레곤), 유럽(아일랜드), 미국 동부(오하이오) 및 아시아 태평양(싱가포르) 리전에서 온디맨드, 스팟, 예약 인스턴스 형식의 7개 크기로 출시되었습니다. 사양은 다음과 같습니다. 인스턴스 이름 vCPU RAM EBS 최적화 대역폭 [ more… ]

Enhancing Non-packaged Desktop Apps using Windows Runtime Components

2019-05-01 KENNETH 0

Enhancing Non-packaged Desktop Apps using Windows Runtime Components Windows 10 Version 1903, May 2019 Update adds support for non-packaged desktop apps to make use of user-defined (3rd party) Windows Runtime (WinRT) Components. Previously, Windows only supported using 3rd party Windows Runtime components in a packaged app (UWP or Desktop Bridge). Trying to call a user-defined Windows Runtime Component in a non-packaged app would fail because of the absence of package identity in the app, no way to register the component with the System and in turn no way for the OS to find the component at runtime. The restrictions blocking this application scenario have now been lifted with the introduction of Registration-free WinRT (Reg-free WinRT). Similar to the classic Registration-free COM feature, Reg-Free WinRT activates a component without using a registry mechanism to store and retrieve information about the component. [ more… ]

Announcing Windows Vision Skills (Preview)

2019-05-01 KENNETH 0

Announcing Windows Vision Skills (Preview) Today, we’re announcing the preview of Windows Vision Skills, a set of NuGet packages that make it easy for application developers to solve complex computer vision problems using a simple set of APIs. Figure 1- From left to right, you are seeing in action the Object Detector, Skeletal Detector, and Emotion Recognizer skills. With Windows Vision Skills, An app developer can use out-of-box WinRT APIs to add pre-built vision skills like object detection, skeletal detection and face sentiment analysis in their Windows applications (.NET, Win32, and UWP). A computer vision developer can leverage hardware acceleration frameworks on Windows devices by packaging their solution as a Vision Skill – without worrying about low-level APIs. All Windows Vision Skills inherit the base classes and interfaces in Microsoft.AI.Skills.SkillInterfacePreview. This open framework can easily be extended to work with [ more… ]
