Enumeration Type Documentation

MemType

enum class fletcher::MemType

strong

Enumeration for different types of memory management.

Enumerator
ANY	Apply the least effort to make the data available to the device. For platforms where the device may access host memory directly, ANY will not copy data to device on-board memory to make it available to the device. If the platform requires a copy to on-board memory, then this will behave the same as the CACHE option.
CACHE	Cache the data to on-board memory of the device. If available, this forces the data to be copied to device on-board memory (e.g. some seperate DRAM chips sitting on the accelerator PCB next to the FPGA, but it could be HBM on top of the FPGA fabric in the same chip, or BRAM. This depends on the platform). Selecting CACHE may result in higher performance if there is data reuse by the kernel, but may result in lower performance if the data is not reused by the kernel (for example fully streamable kernels).
