Question about llvm vectors
...agree, the name does not very well describe what it is
doing. And yes hadd could be summing all the vector elements, but I think
that the usual terminology for that is reduce_add.
In my case I use it for computing the mono signal of a stereo interleaved
signal:
a = load(in);
b = load(in + K);
l = suffle(a, b, 0, 2, 4, 6, ...); // l and r have the same size as a
r = suffle(a, b, 1, 3, 5, 7, ...);
m = .5 * (l + r); // m has the same size as a and b which is maybe optimal
for memory I/O?
store(m, out);
As you said it, I could have m being half of the size of a, and I would not
need to load b. Which...

lists: removing elements, iterating over elements,
...Question: am I deleting the list elements properly?
I do not find explicit documentation for R on how to remove elements
from lists, but trial and error tells me
myList[[5]] <- NULL
will remove the 5th element and then "close up" the hole caused by
deletion of that element. That suffles the index values, So I have to
be careful in dropping elements. I must work from the back of the list
to the front.
Is there an easier or faster way to remove the redundant clusters?
Now, the next question. After eliminating the redundant sets from the
list, I need to calculate the total...

3 questions regarding matrix copy/shuffle/compares
...k). I would like
two independent copies.
(2) If I wanted to change the order of *rows* in my matrix 'pop', is there
an easy way to shuffle these? I don't want to change anything in the
columns, just the complete rowsn (E.g., in Python I could just say
something like suffle(pop) assuming pop is a list of list) - is there
an equivalent for R?
(3) I would like to compare the contents of 'keep_pop' with 'pop'. Though
the order of rows may be different it should not matter as long as
the same rows are present. Again, in Python this would b...

Question about llvm vectors
Hi,
I love llvm vectors, yet I wonder why some advanced vector operations are
specific to some CPU targets?
Let me take an example:
/// Horizontally adds the adjacent pairs of values contained in two
/// 128-bit vectors of [4 x float].
///
/// \headerfile <x86intrin.h>
///
/// This intrinsic corresponds to the <c> VHADDPS </c> instruction.
///
/// \param __a
/// A

Iterative sampling with restrictions
Hi all,
I'm working on a seemingly trivial problem that I can't figure out how
to implement in R. I'd be most grateful for any help here.
I want to do the following: first, randomly assign each of n units to
one of g groups of size n/g. Then, randomly re-assign each of the n
units to a different group (i.e., same as the first step, but the unit
can't be assigned to a group to
