JCuda.cudaMalloc介绍

[英]Allocate memory on the device.

cudaError_t cudaMalloc ( 
void** devPtr, 
size_t size )

Allocate memory on the device. Allocates size bytes of linear memory on the device and returns in *devPtr a pointer to the allocated memory. The allocated memory is suitably aligned for any kind of variable. The memory is not cleared. cudaMalloc() returns cudaErrorMemoryAllocation in case of failure.
[中]在设备上分配内存

cudaError_t cudaMalloc ( 
void** devPtr, 
size_t size )

在设备上分配内存。在设备上分配线性内存的大小字节，并在*devPtr中返回指向已分配内存的指针。为任何类型的变量适当地对齐分配的内存。内存未被清除。如果失败，cudamaloc（）返回cudaerrormoryalLocation。
