#2745: Inclusion of GRHayL library and associated MHD thorns Reporter: Samuel Cupp Status: new Milestone: ET_2023_11 Version: Type: enhancement Priority: major Component: EinsteinToolkit thorn Comment (by Samuel Cupp): For the full library documentation, I point them to the GitHub wiki where we give details on all the library functions. Hopefully that is sufficient. -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2745/inclusion-of-grha…

#2745: Inclusion of GRHayL library and associated MHD thorns Reporter: Samuel Cupp Status: new Milestone: ET_2023_11 Version: Type: enhancement Priority: major Component: EinsteinToolkit thorn Comment (by Samuel Cupp): Sorry if I was unclear before, but we aren’t trying to get the MHD into this release anymore. Just `GRHayLib`, `GRHayLHD(X)`, and `GRHayLID(X)`. I have documentation.tex that I have been working on, but I haven’t finished and pushed it yet. I will update as soon as I do. -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2745/inclusion-of-grha…

#2745: Inclusion of GRHayL library and associated MHD thorns Reporter: Samuel Cupp Status: new Milestone: ET_2023_11 Version: Type: enhancement Priority: major Component: EinsteinToolkit thorn Comment (by Peter Diener): The tests for GRHayLHD now runs, but the new data is for 1 processor whereas the test requirement is for running on 2 processors. The test for GRHayLMHD still sets wrong parameters. After fixing those, the test fails with differences in all output files. GRHayLib has no documentation. I would think that a library in order to be really useful would have documentation that describe the provided interfaces. ‌ ‌ -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2745/inclusion-of-grha…

#2745: Inclusion of GRHayL library and associated MHD thorns Reporter: Samuel Cupp Status: new Milestone: ET_2023_11 Version: Type: enhancement Priority: major Component: EinsteinToolkit thorn Comment (by Samuel Cupp): I ported all the changes made to `GRHayLHD` and `GRHayLID` to the X versions and added a test to `GRHayLHDX.` I also checked that the test looks the same for both versions \(as much as they can with cell/vertex differences\). -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2745/inclusion-of-grha…

#2756: SystemTopology fails to handle Intel CPUs with performance and efficiency cores

#2756: SystemTopology fails to handle Intel CPUs with performance and efficiency cores Reporter: Roland Haas Status: new Milestone: Version: Type: bug Priority: major Component: EinsteinToolkit thorn SystemTopology fails on new Intel CPUs with an assert similar to: ``` cactus_sim: configs/sim/build/SystemTopology/system_topology.cc:471: void {anonymous}::set_bindings(hwloc_topology_t, const mpi_host_mapping_t&): Assertion `num_pus % num_cores == 0' failed. ``` where in the case of a 12th Gen Intel\(R\) Core\(TM\) i7-12700 [https://en.wikipedia.org/wiki/List\_of\_Intel\_Core\_i7\_processors#Golden\… with performance \(16\) and efficiency \(4\) logical cpus hwloc reports: core\_depth 5 num\_cores 12 pu\_depth 6 num\_pus 20 and the assert \`num\_pus % num\_cores == 0\` fails \(b/c only the 8 performance cores have hyperthreads\). This has been reported on the mailing list in [https://lists.einsteintoolkit.org/pipermail/users/2023-August/009036.html](… Not sure if the asserted property is indeed required by SystemTopology or if this is only a sanity check that can be removed without affecting functionality. Certainly performance will be unbalanced between MPI ranks and OpenMP threads that run on P or E cores respectively \(and also if a hyperthread pair was split among two MPI ranks\). This may mostly affect workstations and laptops as I would not expect server class CPUs \(on HPC systems\) to have efficiency cores \(do they?\). -- Ticket URL: https://bitbucket.org/einsteintoolkit/tickets/issues/2756/systemtopology-fa…
