ACCESSING GLOBAL DATA FROM ACCELERATOR DEVICES

摘要

An aspect includes a table of contents (TOC) that was generated by a compiler being received at an accelerator device. The TOC includes an address of global data in a host memory space. The global data is copied from the address in the host memory space to an address in the device memory space. The address in the host memory space is obtained from the received TOC. The received TOC is updated to indicate that global data is stored at the address in the device memory space. A kernel that accesses the global data from the address in the device memory space is executed. The address in the device memory space is obtained based on contents of the updated TOC. When the executing is completed, the global data from the address in the device memory space is copied to the address in the host memory space.

主权项

1. A method for accessing global data from an accelerator device, the method comprising:
receiving, at an accelerator device, a table of contents (TOC) generated by a compiler, the TOC including an address of global data in a host memory space; copying the global data from the address in the host memory space to an address in the device memory space, the address in the host memory space obtained from the received TOC; updating the received TOC to indicate that that global data is stored at the address in the device memory space; executing a kernel that accesses the global data from the address in the device memory space, the address in the device memory space obtained based on contents of the updated TOC; and based on the executing of the kernel completing, copying the global data from the address in the device memory space to the address in the host memory space.
