Upgrade GCC to 9.3.0
by guoge (A) 15 May '20

15 May '20

Hi, dev-team GCC 9.3 has been released on 2020-03-12, and we are ready to upgrade the master branch now. The kernel repo can be compiled through gcc 9.3, no changes needed. Below are the repos that may need to change a little bit, since gcc 9.3 provides libgfortran.so.5, no libgfortran.so.4 provides anymore. atlas future gegl04 gutenprint liberation-fonts liberation-sans-fonts nototools Numpy pcp pygtk2 python-fonttools python-pandas python-pillow python-scikit-learn scipy sil-padauk-fonts suitesparse xsane gimp libvma perl-Archive-Zip perl-MIME-Types the upgrade would be done on May 14th [1], the maintainer of the repos above should look at the daily build report.

测试在华为云 ECS 通过自定义镜像的方式安装了 openEuler(4.19.90-2003.4.0.0036.oe1.aarch64) ,安装成功后发现 yum ,dnf 默认都没有源配置，建议 openEuler 能在ISO 安装配置默认源。

既然这样，那太好了，可以从你最熟悉的地方入手，比如你使用的big data是什么软件栈，可以尝试把你现在用的软件栈(可以具体看)迁移到openeuler上(x86_64和aarch64)，看openeuler上能否满足功能、性能要求，然后我们去弥补差距，这就是很大的贡献。如果你对其他的有兴趣，也可以提出来。 1. 我们的软件库是基于centos还是需要下载源码自己编译? 你说的这些软件库是什么软件库。 2. 我在一个issue里看到您已经跑过spark和TensorFlow。那么最终提供给用户是类似于cloudera这样的集成环境还是原生包让用户选择? 咱们是操作系统，我们要从操作系统的角度思考问题：操作系统不提供这些成熟的商业软件，而是提供基础能力，即当cloudera这样的厂商或使用cloudera的人要在openeuler上使用时，能够很方面的构建、运行起来，功能、性能无损失，甚至有提高。 3. 我是否可以参加下次周会? 是周一还是周五呢？欢迎参加，后面的例会会议通知会提前发到@dev @tc 和sig-ai-bigdata@openeuler.org(筹建中，最近会OK)，所有订阅这三个邮件列表的人都可以收到，并可以接入。祝好。在 2020-05-13 20:48:56，"hao zhang" <unioah(a)gmail.com> 写道：谢谢很详细的讲解。我之前做过一些软件打包，主要是对ubuntu和 archlinux的。我本人一直从事big data方面的开发应用，也算对这一块有些了解。我想我可以先从搭建环境开始， 1. 我们的软件库是基于centos还是需要下载源码自己编译? 2. 我在一个issue里看到您已经跑过spark和TensorFlow。那么最终提供给用户是类似于cloudera这样的集成环境还是原生包让用户选择? 3. 我是否可以参加下次周会? 是周一还是周五呢？谢谢，浩 On Wed, May 13, 2020, 3:44 AM 正心 <sinever(a)126.com> wrote: 浩，你好，非常感谢你的关注，也非常欢迎你的加入。 sig-ai-bigdata的使命如同你在sig的介绍中看到的： 1. 提供openeuler上ai和bigdata的基础运行能力； 2. 提供openeuler上ai和bigdata的竞争力构建； 3. 提供openeuler上ai和bigdata的创新性预研； 4. 提供openeuler上ai和bigdata的新硬件的支持、加速； Openeuler是华为基于上游社区完全从零构建的操作系统，很多软件栈都在构建中，在因此在ai和bigdata上的支持也方兴未艾，当前的首要任务是提供openeuler上ai和bigdata的基础运行能力，包括对各种硬件、各种主流软件包、软件框架的支持，可以做的工作还是很多，如验证典型ai和bigdata软件在openeuler的支持情况，分析他们的依赖，架构梳理，并提供在openeuler的支持(基于openeuler进行构建，提供安装包)，你个人有相关经验吗，如OS打包、ai框架开发使用、bigdata框架的开发使用等或者你个人有什么想法，我们可以讨论或者根据你现有的能力和爱好安排。另外，也欢迎你介绍更多的小伙伴加入进来，一起构建ai和bigdata在openeuler上的未来，期待你的精彩表现。祝 0 error 0 warning sinever | | 正心 | | 邮箱：sinever(a)126.com | 签名由网易邮箱大师定制 On 05/13/2020 00:36, hao zhang wrote: Hi Sinever, 您好，我是新加入到openeuler sig-ai-bigdata 方向的兼职开发人员。根据这次会议的记录，我想在bigdata上面提供帮助。请问具体我可以做些什么？谢谢，浩

Roadmap of GCC & OpenJDK in openEuler
by guoge (A) 12 May '20

12 May '20

Hi, tc-team Please review this roadmap of GCC & OpenJDK, two of most important compilers in OS, any questions are welcomed. GCC: The currently supported gcc version is 7.3, it will be upgraded soon, and there will only be ONE existing repo of GCC, the Compiler SIG has prepared well for the next coming gcc 9.3, and it will the candidate(depends on the compatibility & performance between gcc 9.3 and 10.x) default C/C++ compiler in 20.09 LTS. The Compiler SIG has also started the work of gcc 10.1, GNU has released gcc 10.1 on May 7th. OpenJDK: We will support 3 versions of JDK in openEuler，8/LTS/latest，they are all essential components of a commercial OS. 8: Still the most popular adoption of JDK, about over 50% of applications still run on JDK 8[1]. LTS(11): newest version of LTS but incompatible with JDK 8, supporting modularity/AOT/ZGC/stream enhancement/more efficient G1GC/…, we hope developers migrate their code to Java 11 ASAP. Latest(14): OpenJDK is bootstrap but only supports version n-1, which means you can only compile JDK 14 with JDK 13, JDK 15 with JDK 14, and so on, so the latest release of JDK is needed if we want to support the next LTS(17). We have supported OpenJDK 8 & 11 now, they will be updated quarterly to get critical patch update. The next step is to support the latest version of OpenJDK(14), which is under development.
