Re: [gpfsug-discuss] Pool migration and replicate

No need to specify REPLICATE(1), but no harm either. No need to specify a FROM POOL, unless you want to restrict the set of files considered. (consider a system with more than two pools...) If a file is already in the target (TO) POOL, then no harm, we just skip over that file. From: "Simon

Re: [gpfsug-discuss] Pool migration and replicate

Hallo Simon replication attributes of a file won't be changed just by the fact , that the pool attribute is changed.. or in other words .. if a file gets migrated from POOLA to POOLB, does not change the replication automatically... even if the pool consists of NSDs with multiple fgso depending

[gpfsug-discuss] Pool migration and replicate

Hi all, We'd like to move some data from a non replicated pool to another pool, but keep replication at 1 (the fs default is 2). When using an ILM policy, is the default to keep the current replication or use the fs default? I.e.just wondering if I need to include a "REPLICATE(1)" clause.

Re: [gpfsug-discuss] Singularity + GPFS

Regarding MPI-IO, how do you mean “building the applications against GPFS”? We try to advise our users about things to avoid, but we have some poster-ready “chaos monkeys” as well, who resist guidance. What apps do your users favor? Molpro is one of our heaviest apps right now. Thanks, — ddj

Re: [gpfsug-discuss] Singularity + GPFS

Happy to share on the list in case anyone else finds it useful: We use GPFS for home/scratch on our HPC clusters, supporting engineering applications, so 95+% of our jobs are multi-node MPI. We have had some questions/concerns about GPFS+Singularity+MPI-IO, as we've had issues with GPFS+MPI-IO

Hi Lohit, Nathan Would you be willing to share some more details about your setup? We are just getting started here and I would like to hear about what your configuration looks like. Direct email to me is fine, thanks. Bob Oesterlin Sr Principal Storage Engineer, Nuance From:

Re: [gpfsug-discuss] Singularity + GPFS

I have my own sandbox set up to explore this, but nothing worth reporting just yet. I too though would be interested in any wisdom that others can share. Daniel  

Re: [gpfsug-discuss] Singularity + GPFS

We do run Singularity + GPFS, on our production HPC clusters. Most of the time things are fine without any issues. However, i do see a significant performance loss when running some applications on singularity containers with GPFS. As of now, the applications that have severe performance issues

Re: [gpfsug-discuss] Singularity + GPFS

We are running on a test system at the moment, and haven't run into any issues yet, but so far it's only been 'hello world' and running FIO. I'm interested to hear about experience with MPI-IO within Singularity. On 26 April 2018 at 15:20, Oesterlin, Robert wrote:
