Hi Xuwen, The release mpich-4.1.2 contains hydra-4.1.2. There is no difference. The hydra release is for those users who only need the job launcher. --- Hui Zhou ________________________________ From: Xuwen XW3 Dai via discuss <[email protected]> Sent: Monday, June 12, 2023 8:59 PM To: [email protected] <[email protected]> Cc: Xuwen XW3 Dai <[email protected]> Subject: [mpich-discuss] Ask for help with MPICH ********************************** IMPORTANT NOTICE: This email is from a third-party vendor and its personnel who provide services to Lenovo,and this email is not legally binding on Lenovo.

Recently, we are developing a project on a supercomputing platform, and we need to use the PBS scheduler to run the linpack job, and the mpi used is MPICH. I would like to ask what is the difference between mpich-4.1.2 (stable release) and hydra-4.1.2 (stable release) in the download options provided by the project official website? The linpack job I compiled using MPICH-4.1.2 can run, but PBS cannot obtain all the job process information of the multi-machine nodes. However, I use hydra-4.1.2 to run the linpack multi-machine job, and pbs can get the process information of all nodes. I can't understand the difference between the two installation packages hydra-4.1.2 and mpich-4.1.2 from the documents you provided, and I hope to get your help, thank you. This email uses Google translation, I hope you can understand it. Hi，MPICH的开发者你好，我是戴旭文，一名联想公司的开发人员。 最近我们在开发一个超算平台的项目，需要使用PBS调度器来运行linpack作业，使用的mpi是MPICH。 我想请问一下项目官网提供的下载选项里面，mpich-4.1.2 (stable release)和hydra-4.1.2 (stable release)有什么区别？我使用MPICH-4.1.2编译的linpack作业可以运行，但是PBS获取不到多机节点的所有作业进程信息。但是，我使用hydra-4.1.2 来运行的linpack多机作业，pbs就可以获取所有节点的进程信息。 我从你们提供的文档里无法理解hydra-4.1.2 和mpich-4.1.2这两个安装包的区别，希望能得到您的帮助，谢谢。 这封邮件使用谷歌翻译，希望您能看懂 BRs Dai Xuwen
