Detailed Description

template<GT_MMAP_METHOD MM, typename... VARS>
class gtpin::GtMapped< MM, VARS >

Template container of host-to-device mapped variables.

Parameters:

MM	The method of the memory mapping and sharing
VARS	Types of variables to be mapped

   Usage:
      auto mySharedVars      = GtMakeShared(myVar1, myVar2);        // Declare myVar... variables as host<->device synchronized
      auto mySharedConstVars = GtMakeSharedConst(myCvar1, myCvar2); // Declare myCvar... variables as host->device synchronized
      auto mySharedRetVars   = GtMakeSharedRet(myRvar1, myRvar2);   // Declare myRvar... variables as host<-device synchronized
      
      MyTool::OnKernelBuild(IGtKernelInstrument& instrumentor)
      {
          auto& mapper = instrumentor.MemoryMapper();
          mySharedVars.Map(mapper);        // Share myVar... variables using GT_MMAP_SHARE method
          mySharedConstVars.Map(mapper);   // Share myCvar... variables using GT_MMAP_SHARE_CONST method
          mySharedRetVars.Map(mapper);     // Share myRvar... variables using GT_MMAP_SHARE_RET method
      }
