<p class="x_MsoNormal"><span lang="EN-US">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.</span></p>
<p class="x_MsoNormal"><span lang="EN-US">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.</span></p>
<p class="x_MsoNormal"><span lang="EN-US">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.</span></p>
