Even so, GPU programming types (CUDA, HIP) are hardware dependent. To be able to allow for products to generally be deployed on as quite a few HPC techniques as you can, preserving numerous programming models inside the source code that focus on distinctive HPC architectures results in being necessary. While this ends in complex code and elevated program upkeep initiatives (specialized credit card debt), not offering these abilities will drastically Restrict the design's applicability in “true-world” use scenarios (Hokkanen et al., 2021). You will find further difficulties when porting application across HPC devices associated with supporting strong and common workflows to cope with various software stacks, file devices, schedulers, etc. We don't tackle these difficulties Within this paper.
