Nvidia cuda driver api

Otherwise, the compatible mode is disabled. Used internally, for example, to handle unaligned IO and optimal IO path routing. This value might be rounded down to the nearest GPU page size. This might be rounded down to the nearest GPU page size. If poll mode is enabled, an IO size less than or equal to the threshold value is used for polling.

Parameters poll Boolean to indicate whether to use the poll mode. The default value is 4KB. See the following for more information: cuFileDriverGetProperties. The max direct IO size must be 4K aligned. The default value is KB. Description This API is used with cuFileGetDriverProperties and is used to set the maximum direct IO size used by the library to specify the nvidia-fs kernel driver the maximum chunk size in which the latter can issue IO to the underlying filesystem.

Refer to the following for more information: cuFileDriverGetProperties. The max cache size must be 4K aligned. The max pinned size must be 4K aligned.

The default value corresponds to the maximum PinnedMemory or the physical memory size of the device. This API overrides the default value that may be set by the properties. The following table lists the usage of different configuration parameters: Configuration Parameter Description logging:dir The log directory for the cufile.

If the log directory has not been enabled, the log file is created under the current working directory. ERROR indicates log critical errors only.

DEBUG indicates the log information that includes error, informational, and debugging the library. The default value is set to 16MB. The default value is set to MB.

Polling might be useful for small IO transactions. The default value is false. The purpose is to test newer file systems for environments where GDS applications do not have the kernel driver installed, or for comparison tests.

This is applicable for reads and writes. Not applicable for DFS. Parameters fh Valid pointer to the OS-neutral cuFile handle structure supplied by the user but populated and maintained by the cuFile runtime.

But if compatibility mode is enabled, then this requirement is relaxed. It is recognized that in order to be fully compatible, cuFileHandleRegister should not limit the set of flags that are supported, relative to a POSIX pread or pwrite.

But those conditions are not fully tested. We anticipate additional relaxation on restrictions over time. Parameters fh File descriptor for the file. However, GDS functionality does not take any special responsibility for writing that metadata back to permanent storage.

The data is not guaranteed to be present after a system crash unless the application uses an explicit fsync 2 call. See the following for more information: cuFileBufDeregister. If non-NULL, the action is ordered in the stream. The current context of the caller is assumed. Parameters fh The cuFile handle for the file.

The number of bytes successfully read. All other errors return a negative integer value of the CUfileOpError enum value. CUDA stream in which to enqueue the operation. If NULL, make this operation synchronous. All other errors will return a negative integer value of the CUfileOpError enum value. The value must be greater than 0. Notices Notice This document is provided for information purposes only and shall not be regarded as a warranty of a certain functionality, condition, or quality of a product.

If true , falls back to using compatibility mode when the library detects that the buffer file descriptor opened cannot use GPUDirect Storage. If false , forces compatibility mode to be used for writes even when the underlying file system is capable of performing GPUDirect Storage writes. Batch Read. Batch Write. The initial value. Set once enqueued into the driver. Invalid parameters. Successfully completed. The operation has timed out.

You can update the device driver from the following locations:. Adobe supports those versions of Windows and macOS that are still actively supported by Microsoft and Apple. For macOS, that typically means the three most recent versions. That holds true for the latest releases as well.
