• torch.backends.cuda.cufft_plan_cache.clear()清空缓存。 如果不是管理和查询默认设备,你可以通过torch.backends.cuda.cufft_plan_cache索引到对应的设备对象,然后你就可以访问到上面列举出来的属性,例如设置设备1的缓存容量,你可以写成torch.backends.cuda.cufft_plan_cache[1].max_size = 10。 运行时编译 p...
一种可行的解决方案:在代码中设置CUDA_VISIBLE_DEVICES环境变量后,调用torch.cuda.device_count.cache_clear(),例如: importos os.environ['CUDA_VISIBLE_DEVICES']="1"importtorch torch.cuda.device_count.cache_clear()
答案是不能。用CUDA 写光栅化器的很多,但是说要完备(部分)的模拟绘制管线的工作很少,公开的基本上只...

相反,只能在 MPS 服务器启动时通过环境变量 CUDA_DEVICE_DEFAULT_PERSISTING_L2_CACHE_PERCENTAGE_LIMIT 指定预留大小。 3.2.3.2 L2持久化访问策略 访问策略窗口指定全局内存的连续区域和L2缓存中的持久性属性,用于该区域内的访问。 下面的代码示例显示了如何使用 CUDA 流设置L2持久访问窗口。 cudaStreamAttrValue ...
size_t size = min(int(prop.l2CacheSize * 0.75), prop.persistingL2CacheMaxSize); cudaDeviceSetLimit(cudaLimitPersistingL2CacheSize, size); /* set-aside 3/4 of L2 cache for persisting accesses or the max allowed*/ 在多实例 GPU (MIG) 模式下配置 GPU 时,L2 缓存预留功能被禁用。

libcudacxxis the CUDA C++ Standard Library. It provides an implementation of the C++ Standard Library that works in both host and device code. Additionally, it provides abstractions for CUDA-specific hardware features like synchronization primitives, cache control, atomics, and more. ...
