Detailed Description
device-specific data for these lauch params - each instance needs its own host- and device-side memory to store the parameter values (to avoid messing with other launches if and when we use multiple async launches in parallel!)
Constructor & Destructor Documentation
◆ DeviceData()
| owl::LaunchParams::DeviceData::DeviceData | ( | const DeviceContext::SP & | device, |
| size_t | dataSize | ||
| ) |
constructor, which allocs all the device-side data
Member Data Documentation
◆ deviceMemory
| DeviceMemory owl::LaunchParams::DeviceData::deviceMemory |
the cuda device memory we copy the launch params to
◆ hostMemory
| PinnedHostMem owl::LaunchParams::DeviceData::hostMemory |
host-size memory for the launch paramters - we have a host-side copy, too, so we can leave the launch2D call without having to first wait for the cudaMemcpy to complete
◆ stream
| cudaStream_t owl::LaunchParams::DeviceData::stream = nullptr |
a cuda stream we can use for the async upload and the following async launch
The documentation for this struct was generated from the following files:
- owl/LaunchParams.h
- owl/LaunchParams.cpp
