Example 1 with ServerIntFloatRow

use of com.tencent.angel.ps.storage.vector.ServerIntFloatRow in project angel by Tencent.

the class RowSplitCombineUtils method combineServerIntFloatRowSplits.

private static Vector combineServerIntFloatRowSplits(List<ServerRow> rowSplits, MatrixMeta matrixMeta, int rowIndex) {
    int colNum = (int) matrixMeta.getColNum();
    int elemNum = 0;
    int size = rowSplits.size();
    for (int i = 0; i < size; i++) {
        elemNum += rowSplits.get(i).size();
    }
    IntFloatVector row;
    if (elemNum >= (int) (storageConvFactor * colNum)) {
        row = VFactory.denseFloatVector(colNum);
    } else {
        row = VFactory.sparseFloatVector(colNum, elemNum);
    }
    row.setMatrixId(matrixMeta.getId());
    row.setRowId(rowIndex);
    Collections.sort(rowSplits, serverRowComp);
    int clock = Integer.MAX_VALUE;
    for (int i = 0; i < size; i++) {
        if (rowSplits.get(i) == null) {
            continue;
        }
        if (rowSplits.get(i).getClock() < clock) {
