@luraess and I have been testing MPI.jl on OLCF's Crusher which uses cray-mpich. Runs execute as independent MPI processes, we think the issue is that MPIPreferences can't recognize the cray-mpich...
The following error appears for a large ROCArray, 50Kx50K (or larger) Float32 on `AMDGPU.rand!` It points at [this line in random.jl](https://github.com/JuliaGPU/AMDGPU.jl/blob/master/src/rand/random.jl#L50) and might be related to using `Int32`. To reproduce:...
Large array literals (hardcoded values in code): ```julia mats[1:34,1] = Int32[ 58, 59, 60, 61, 40, 42, 43, 44, 45, 46, 1, 2, 3, 7, 8, 9, 10, 29, 57,...
## Proposed changes - Refactor ProjectData class to meet coding standards - Add `is_complex` static variable for start migration from compile-time `QMC_COMPLEX` - Add unit test Related to #4099 ##...
**Is your feature request related to a problem? Please describe.** Currently QMCPACK separates `real` and `complex` functionality at compile-time. Thus, stakeholders need to create two separate executables to test, deploy...

**Is your feature request related to a problem? Please describe.** Currently, when PRs come simultaneously they get out-of-sync with any changes to the target `develop` branch. The goal is to...
In a recent [study](https://dl.acm.org/doi/10.1145/3624062.3624278) on Frontier, a 7-point stencil kernel under performs at half the bandwidth (~300 GB/s) of its HIP counterpart (~600 GB/s) on a single MI250x. The behavior...
The question is three-fold: 1. What's the best way to generate random numbers (not arrays) on device kernel code. 2. When trying `AMDGPU.randn(eltype(u), 1)` or `randn(eltype(u), 1)` (from Base), AMDGPU.jl...
**Describe the bug** Not a bug, but mostly to report that the current GrayScott.jl under simulations is outdated. The updated version can be found at [JuliaORNL/GrayScott.jl](https://github.com/JuliaORNL/GrayScott.jl) Asking the experts, I...
