Sessions WG agenda items for today?
by Pritchard Jr., Howard 31 Oct '22

31 Oct '22

HI All, Does anyone have agenda items they would be prepared to discuss today? If not I suggest canceling. However, if we do meet, remember for non-EU (UK?) folks, we will be starting an hour later as EU (or at least Berlin) is back on regular time. At the next joint meeting with FT, we will continue discussions of the mpiexec hard/soft, MPI_Comm_spawn and errors and all that. At some point soon we should resume discussion of dynamic process sets/groups and related topics, but I myself am not ready to discuss these topics in depth today.

Hi All, I have a conflict and will not be able to attend the Sessions WG meeting later today. I suggest we cancel and pick up next week with the FT WG to pick up on the discussion from last week of a couple of items: * Fault tolerance and MPI\_Comm\_create\_from\_group * Range/context for errors Thanks, Howard — [signature_61897647] Howard Pritchard Research Scientist HPC-ENV Los Alamos National Laboratory howardp(a)lanl.gov [signature_2377146383]<https://www.instagram.com/losalamosnatlab/>[signature_3282098556]<https://twitter.com/LosAlamosNatLab>[signature_1424968369]<https://www.linkedin.com/company/los-alamos-national-laboratory/>[signature_2273420083]<https://www.facebook.com/LosAlamosNationalLab/>

Hi folks As per my promise, I have created the DynaSched github web page and included the paper I published way back in the early 00's plus some references I accumulated at that point. I'm sure you folks have access to paper archives and can easily update those references (I don't, I'm afraid). https://dynasched.github.io/ <https://dynasched.github.io/> HTH Ralph > On Oct 3, 2022, at 1:25 PM, Pritchard Jr., Howard <howardp(a)lanl.gov> wrote: > > Thanks Ralph!

Schedulers et al

Hi folks I thoroughly enjoyed today's discussion about schedulers and their interactions with applications. Martin had asked about papers/info on the Lagrangian Receding Horizon dynamic scheduler and dynamic schedulers in general - I am going to setup a collection of references on the subject on the DynaSched github web page and will post it here. Give me a day to do it - I remain rather groggy from all the drugs to manage the back pain. Howard had also asked about the definition of static vs dynamic schedulers. I have attached a writeup I recently provided to my "boss" on the subject. Thanks again for the discussion - I look forward to continuing it at the PMIx Tools WG! Ralph
