A Doubt about the Source Code of MSCCL #61
Description
I am currently studying the source code of MSCCL, I have some doubts about the count variable in this structure. What does it mean?
// TODO: compress this by a lot!
struct mscclTransfer {
int16_t srcoffset;
int16_t dstoffset;
uint8_t srcbuffer; // follow MSCCL_THIS_INPUT/MSCCL_THIS_OUTPUT macros
uint8_t dstbuffer; // follow MSCCL_THIS_INPUT/MSCCL_THIS_OUTPUT macros
int16_t depencePointer; // index to the first dependence
int16_t numDependences; // depencePointer+numDependences indicate the last dependence
int8_t has_dependence;
int16_t numReductions; // number of reductions with the same dst
int16_t reductionPointer; // where the reduction starts
uint8_t type;
//--------------//
uint8_t count; //
//--------------//
};
