问题 I wrote the following code for calling Metis using Fortran and C, but still getting segmentation fault. The target of the code is to do partition for the input file chanelElements . module metis_vars use iso_c_binding !

How to install METIS on ubuntu

别说谁变了你拦得住时间么 提交于 2019-12-18 08:52:30
问题 I want to install the METIS package on ubuntu. I tried the instructions on the install.txt file which says to use $ make install which I did, after installing make as well. I also tried the sudo apt-get install metis which installed it successfully but when trying to use it in both cases I get metis.h: No such file in directory compilation terminated In case anyone asks I use g++ -I/path/to/file myprogram.cpp to specify the path where metis.h is. I believe I haven't done something correct in

How to install METIS package in python on windows?

老子叫甜甜 提交于 2019-12-13 20:04:07
问题 I am currently running a source code in python which uses METIS. I wanted to run it using Jetbrains PyCharm, conda interpreter and these are installed on windows 10. Although I have installed METIS using conda, I could not enable shared libraries and I faced this error: ModuleNotFoundError: No module named 'metis' When I tried to run it without conda I faced the following error although I have added the metis.dll location to the environment variables. RuntimeError: Could not load METIS dll

Interpretation of 'ufactor' on a toy graph clustering

问题 I am trying to do a imbalanced partition by METIS. I do not need equal number of vertices in each cluster(which is done by default in METIS). My graph has no constraints, it's a undirected unweighted graph. Here is a example toy graph clustered by METIS without no ufactor parameter. Then, i tried with different ufactor and at value 143, METIS starts to do the expected cluster like the following- Can anybody interpret this. Eventually, I want to find a way to guess an ufactor from any

Linux could not find metis.h

问题 I am trying to install Metis. Since I am working on a public server, I couldn't install it as a root user. So I have installed metis in my account /home/jd/metis. When I try to execute something, I get fatal error: metis.h: No such file or directory I guess the system looks for metis.h under /usr/local/include but couldnt find it there. How do I make linux look for metis.h under /home/jd/metis/include directory? I added this path to the $PATH variable. But still the same error. Please advise.

METIS seg faults when run from Fortran

牧云@^-^@ 提交于 2019-12-02 05:43:52
问题 I'm trying to use the METIS library for mesh partitioning as part of a Fortran program I've written for finite element computations. METIS is written in C but it's supposed to work just fine with Fortran 90. But I keep getting seg faults. One potential hiccup is that there are a few arguments to which I'm giving null pointers. Some other folks have had trouble getting a call to a C function from fortran to recognize a null pointer object. That was addressed here and I don't think that's the

首个智能运维项目开源!腾讯织云Metis,用算法替代人为指定规则

10月20日,腾讯织云Metis 智能运维学件平台在OSCAR开源先锋日上宣布,正式对外开源。Metis 是AIOps(Algorithmic IT Operations),即智能运维领域的首个开源产品。智能运维主张通过算法从海量运维数据中学习摸索规则,逐步降低对人指定规则的依赖,进而减少人为失误。 OSCAR 开源先锋日由中国信息通信研究院主办,中国信通院云大所所长何宝宏,中国信通院云大所云计算部副主任栗蔚,腾讯云副总裁赵建春,腾讯云运营部总经理肖世广共同参与Metis开源发布仪式。 (腾讯织云“Metis”开源项目正式发布) 腾讯云副总裁赵建春表示:“人工智能与运维的结合有了AIOps的新概念,如何在智能运维领域寻求到新的突破,从传统 API 转向运维学件,将腾讯海量数量训练出来的模型贡献开源社区和业内,我想这就是织云Metis 智能运维学件开源的意义,和大家共建 AI 运维场景,让人工智能和运维紧密结合。” (腾讯云副总裁赵建春) 在“腾讯织云Metis 智能运维学件平台”这一命名中,“学件”的概念由南京大学周志华教授提出。学件 = 模型 + 规约,具有可重用、可演进、可了解的特性。在此基础上,腾讯云副总裁赵建春先生进一步提出“运维学件”的概念,亦称 AI 运维组件,强调其具备对运维场景智能化解决方案的记忆能力。 “织云”指的是腾讯智能一体化运维平台,而“Metis

10月20日,腾讯开源三大运维开源项目——TARS、蓝鲸和织云Metis首次集结,参与了由中国信息通信研究院主办、云计算标准与开源推进委员会承办的 “OSCAR开源先锋日”。会上,腾讯开源团队与前线的技术工程师面对面交流运维经验,积极投入开源社区的建设。 在会上,腾讯开源运营负责人王春雨分享了腾讯自下而上做开源的历程。据了解,腾讯开源起始于2010年。在过去六年里,腾讯围绕做好开发者体验,实现从内部开源到对外开源,从开源新兵到开源先行者的跨越。在王春雨看来,好的开源不仅仅是代码、程序,更是一个建筑之上的、有着规则和制度的社区,是Community over Code。腾讯希望推动开源从技术驱动走向商业战略,凭借持续不断的技术创新,建设共赢的、健康的开发者生态。 (腾讯开源运营负责人王春雨) 作为本次活动的一大亮点,腾讯织云Metis 智能运维学件平台在会上正式宣布开源。Metis 是智能运维领域的首个开源产品,旨在通过算法从海量运维数据中学习摸索规则,逐步降低对人指定规则的依赖,减少人为失误。目前,Metis在运维质量、效率、成本三个方面逐步构建出成熟的智能化运维场景,从质量保障、效率提升、成本管理、智能检测、通用模型和规则学习6个方面大幅提升运维人员的工作效率。 (腾讯织云“Metis”开源发布仪式) 此次大会也是继今年3月,TARS与信通院宣布展开深度合作后的再度携手。TARS
