Summary
editDescriptionIKJikj.gif |
English: Animation of blocked matrix multiplication in IKJikj order:
for ( int iMacroRow = 0; iMacroRow < rnRows ; iMacroRow += bs ) // I for ( int iMacroSum = 0; iMacroSum < rnCols ; iMacroSum += bs ) // K for ( int iMacroCol = 0; iMacroCol < rnColsB; iMacroCol += bs ) // J for ( int iRow = iMacroRow; iRow < std::min( iMacroRow+bs,rnRows ); ++iRow ) // i for ( int iSum = iMacroSum; iSum < std::min( iMacroSum+bs,rnCols ); ++iSum ) // k for ( int iCol = iMacroCol; iCol < std::min( iMacroCol+bs,rnColsB); ++iCol ) // j C[i,j] += A[i,k]*B[k,j]Currently accessed elements are marked red. To the right is the memory representation of the matrices, thereby allowing to see problems caused by strides and non-linear access. |
