support libraries for unstructured mesh particle in cell simulations on GPUs and CPUs
While developing on a new particle code, `Comet`, I encountered the following issue: - If using `CabM` particle structure, when the number of particles per GPU is `>~50 million`, information...
This is a summary of [issue #418](https://github.com/SCOREC/core/issues/418) as it is more appropriate here. For a simple partitioned mesh: rectangular domain with 4 mesh parts, the vertex classification on some mesh...
Tried to do a partition of the mesh toroidally into 512 parts Failed with the following core file output (successful upto 256 parts). ``` #0 0x0000000000882a38 in std::tuple::tuple(long const&) ()...
We've noticed some strange behavior for the pseudo-push operation on our performance tests. The code for this test is located [here](https://github.com/SCOREC/pumi-pic/blob/acf7a6a917d391ccb9a61971bc39d3cd349462f7/performance_tests/ps_combo160.cpp#L143-L179). On multiple tests we've seen some seemingly random patterns...
I've been working on the `cabmBuild` branch and noticed that we have some unexpected behavior while testing `CSR`. A new version of the testing code, `ps_combo.cpp`, was made to test...
After creating the DPS data structure and initializing the particles with the participle velocity, particles are not found in the element. This doesnot happen till ~20 million particles/GPU but on...
