GPU 딥러닝 모델 학습에 있어서 Amazon EC2 스팟 인스턴스의 활용법

2019-05-31 KENNETH 0

GPU 딥러닝 모델 학습에 있어서 Amazon EC2 스팟 인스턴스의 활용법 여러분이 데이터 세트를 수집하고, 심층 신경망 아키텍처를 설계하고, 학습 루틴 코드를 작성을 완료 하셨다면 지금부터는 강력한 GPU 인스턴스를 사용해 여러 epoch에 걸쳐 대규모 데이터 세트를 이용한 학습을 실행할 차례입니다. 여러분은 이미 NVIDIA Tesla V100 GPU에 기반한 Amazon EC2 P3 인스턴스가 컴퓨팅 집약적인 딥러닝 학습 작업에 적합하다는 사실을 알고 있지만 예산이 빠듯한 관계로 가능한한 학습 비용은 낮추고 싶습니다. 몇 시간 또는 며칠에 걸쳐 학습 작업을 실행하는 딥러닝 연구자 및 개발자라면, 스팟 인스턴스 요금을 통해 훨씬 경제적인 비용으로 고성능 CPU를 이용할 수 있습니다. 스팟 인스턴스를 사용하면 온디맨드 요금에 비해 대폭 할인된 가격으로 여분의 Amazon EC2 컴퓨팅 용량에 액세스할 수 있습니다. 인스턴스 및 리전별 최근 요금 목록을 보려면 스팟 인스턴스 어드바이저를 방문하십시오. 스팟 인스턴스와 온디맨드 인스턴스 사이의 주요 차이점을 알아보려면 이 Amazon EC2 사용 설명서를 검토해 보시기 바랍니다. 스팟 인스턴스는 딥러닝 워크플로우에 적합하지만, 온디맨드 [ more… ]

A Reminder to Update Your Systems to Prevent a Worm

2019-05-31 KENNETH 0

A Reminder to Update Your Systems to Prevent a Worm On May 14, Microsoft released fixes for a critical Remote Code Execution vulnerability, CVE-2019-0708, in Remote Desktop Services – formerly known as Terminal Services – that affects some older versions of Windows. In our previous blog post on this topic we warned that the vulnerability is ‘wormable’, and that future malware that exploits this vulnerability could propagate from vulnerable computer to vulnerable computer in a similar way as the WannaCry malware spread across the globe in 2017.   Microsoft is confident that an exploit exists for this vulnerability, and if recent reports are accurate, nearly one million computers connected directly to the internet are still vulnerable to CVE-2019-0708. Many more within corporate networks may also be vulnerable. It only takes one vulnerable computer connected to the internet to provide a potential [ more… ]

Ask NGINX | May 2019 Every month, we take a moment to share the expertise of our team, and answer a number of great questions we’ve received from both our customers and open source users. These questions range from how to use our products in a variety of use cases to how to effectively integrate third‑party tools and platforms with NGINX. These answers come from our experts including technical architects, systems engineers, and our award‑winning customer support specialists. How do I perform health checks for UDP servers in a load‑balanced upstream server group? Both NGINX Open Source and NGINX Plus perform passive UDP health checks by default: if a UDP server generates an error or times out in response to just one request, it is marked unavailable and removed from the load‑balancing rotation for ten seconds. You can change the defaults [ more… ]

USN-4001-2: libseccomp vulnerability

2019-05-31 KENNETH 0

USN-4001-2: libseccomp vulnerability libseccomp vulnerability A security issue affects these releases of Ubuntu and its derivatives: Ubuntu 14.04 ESM Summary libseccomp could allow unintended access to system calls. Software Description libseccomp – library for working with the Linux seccomp filter Details USN-4001-1 fixed a vulnerability in libseccomp. This update provides the corresponding update for Ubuntu 14.04 ESM. Original advisory details: Jann Horn discovered that libseccomp did not correctly generate 64-bit syscall argument comparisons with arithmetic operators (LT, GT, LE, GE). An attacker could use this to bypass intended access restrictions for argument-filtered system calls. Update instructions The problem can be corrected by updating your system to the following package versions: Ubuntu 14.04 ESM libseccomp2 – 2.4.1-0ubuntu0.14.04.2 To update your system, please follow these instructions: https://wiki.ubuntu.com/Security/Upgrades. This update uses a new upstream release which includes additional bug fixes. In general, a [ more… ]
