WebSep 26, 2024 · The unified memory feature available in recent GPU architectures introduces another option, implicit management. However, our experiments show that it incurs several performance issues, especially under GPU memory oversubscription. In this paper, we propose a compiler and runtime collaborative approach to manage OpenMP GPU data … WebNov 11, 2024 · Popular deep learning frameworks like PyTorch utilize GPUs heavily for training, and suffer from out-of-memory (OOM) problems if memory is not managed properly. CUDA Unified Memory (UM) allows the oversubscription of tensor objects in the GPU, but suffers from heavy performance penalties.

Examples of CR_Memory, CR_Socket_Memory, and CR_CPU_Memory type consumable resources Of the three different memory allocation strategies for GPU oversubscription using Unified Memory, the optimal choice for an allocation method for a given application depends on the memory access pattern and reuse of on-GPU memory. When you are choosing between the fault and the pinned system … See more To evaluate Unified Memory oversubscription performance, you use a simple program that allocates and reads memory. A large … See more In this test case, the memory allocation is performed using cudaMallocManagedand then pages are populated on system (CPU) memory in the following way: Then, a GPU kernel is executed and the performance of the … See more For the fault-driven migration explained earlier, there is an additional overhead of the GPU MMU system stalling until the required memory range is available on GPU. To overcome this overhead, you can distribute memory … See more As an alternative to moving memory pages from system memory to GPU memory over the interconnect, you can also directly access the pinned … See more Webof GPU architecture have led to wider adoption of GPUs by general purpose applications [10], [24]. Traditionally, ... oversubscription, and (ii) sparse accesses benefit from low latency direct access.
