[slurm-dev] Re: Setting up Environment Modules package

2017-10-05 Thread Blomqvist Janne
Hi, what we do is, roughly, a combination of your options #2 and #3. To start with, however, I'd like to point out that we're using Lmod instead of the old Tcl environment-modules. I'd really recommend you to do the same. So basically, we have our modules available on NFS, both the module

[slurm-dev] RE: Slurm array scheduling question

2016-09-21 Thread Blomqvist Janne
Hi, AFAIU the major optimization wrt. array job scheduling is that if the scheduler finds that it cannot schedule a job in a job array, it skips over all the rest of the jobs in the array. There's also some memory benefits, e.g. a pending job array is stored as a single object in the job

[slurm-dev] RE: multifactor2 priority weighting

2015-05-28 Thread Blomqvist Janne
Hi, much as I'd be sad to see my baby go, I agree with you that fair-tree is a better choice. So, +1. Furthermore, could the fair-tree algorithm be made the default when priority/multifactor is used? Is there any case where the current default is objectively better than fair-tree? -- Janne

2014-11-06 Thread Blomqvist Janne
Hi, as was already explained, the users/group DB must be available on all nodes. For your other question, why there is munge?, munge provides a mechanism to solve the problem of a slurm daemon receiving a message claiming to be from UID=12345; how can it verify that this is true and not a

11.2 Hi, Yes, that seems to be the problem. Can someone point me in the right direction to change the compile scripts? I'm willing to put some effort into this, but I don't really know where to start. - Jan On Tue, Sep 30, 2014 at 10:59 PM, Blomqvist Janne janne.blomqv

Hi, xcgroup.c (src/slurmd/common/xcgroup.c) handles the Linux-specific cgroups (https://en.wikipedia.org/wiki/Cgroups) stuff. Judging from your error message it appears that the solaris mount() function is different from the Linux one. But it doesn't really matter anyway, since cgroups don't

[slurm-dev] RE: fairshare - memory resource allocation

2014-07-30 Thread Blomqvist Janne
Hi, if I understand it correctly, this is actually very close to Dominant Resource Fairness (DRF) which I mentioned previously, with the difference that in DRF the charge rates are determined automatically from the available resources (in a partition) rather than being specified explicitly by

Hi, we had a slightly similar setup on an older cluster; - The frontend and the home directories were the same system - Home dirs were physically under /export/home - Compute nodes mounted the home dirs over NFS using the automounter at /home/$USER This sounds a bit like the situation you

[slurm-dev] Re: accounting same share

2013-05-03 Thread Blomqvist Janne
Hi, if you're on slurm 2.5 or newer, I recommend taking a look at the priority_multifactor2 plugin. It differs from the original priority_multifactor plugin by using a different algorithm for calculating fair-share priorities which makes a difference particularly when using account
