Note:
PackedList constructor initializes to zero, faster not to do it
ourselves.
ie,
PackedList foo(nPoints);
vs.
PackedList foo(nPoints, 0);
saves an extra nPoints operations with shifts/masks etc.
If speed is important, change this type of code
PackedList isMaster(nPoints, 1u);
for (loop)
{
if (condition)
{
isMaster.set(i, 0u); // unset bit
}
}
return isMaster;
into this:
PackedList notMaster(nPoints);
for (loop)
{
if (!condition)
{
notMaster.set(i, 1u);
}
}
notMaster.flip();
return notMaster;
or this:
PackedList isMaster(nPoints);
isMaster.flip();
for (loop)
{
if (condition)
{
isMaster.set(i, 0u);
}
}
return isMaster;
