Hardware cluster requirements

[josian]

Hi,

We are exploring use Trinity with HPC and PBS in our lab. This is our hardware:

ServerA: QuadCore CPU and 8Gb RAM
ServerB: 16Cores and 128Gb
ServerC: 32Cores and 128Gb

Can we use ServerA as master and ServerB & ServerC as nodes? In that way the bigger servers can work in parallel and master server just manage the scheduler.

Your plan is spot on,

ServerA: QuadCore CPU and 8Gb RAM – PBS Pro Server/Sched
ServerB: 16Cores and 128Gb - PBS MoM ( compute node 1 )
ServerC: 32Cores and 128Gb - PBS MoM ( compute node 2)

Note: To avoid confusion of the word “server” in this context
PBS Server/Scheduler - distributes or schedules the jobs based on policy/limits etc
PBS Mom (Compute Nodes) – does the computational work

Thanks for the info and the clarification.

Is there any official documentation for OpenPBS? I found a website but is an interpretation of the concepts.

Documentation can be found at this link: https://www.pbsworks.com/SupportGT.aspx?d=PBS-Professional,-Documentation

Please note this is PBS Pro OSS and not OpenPBS, some information below:

PBS Default number of nodes and number of cpus

So a little history for your knowledge. PBS was originally developed for NASA under a contract project. Altair Engineering acquired the rights to all the PBS technology and intellectual property from Veridian in 2003. Altair Engineering currently owns and maintains the intellectual property associated with PBS, and also employs the original development team from NASA. The following versions of PBS are currently available: OpenPBS — original open source version released by MRJ in 1998 (not ac…
