Memory management strategies

The purpose of this exercise is to compare 6 different memory management strategies and their computational overhead. The following functions are called at the end of this file by the main() function:

  • The function explicitMem() represents a basic explicit memory management strategy
  • The function explicitMemPinned() represents an explicit memory management strategy with pinned host memory
  • The function explicitMemNoCopy() represents an explicit memory management strategy where the data can reside at GPU memory during an iterative loop (no recurring memory copies needed)
  • The function unifiedMem() represents a basic unified memory management strategy
  • The function unifiedMemPrefetch() represents a unified memory management strategy with prefetching
  • The function unifiedMemNoCopy() represents a unified memory management strategy where the data can reside at GPU memory during an iterative loop (no recurring memory copies needed)

The task is to fill the missing function calls in the code indicated by lines beginning with #error, and followed by a descriptive instruction. To compile this rocm/5.3.3 is needed, older rocm modules do not support memory asynchronous malloc/free (they hang)
