	Fast Parallel Permutation Algorithms

Abstract:
We investigate the task of permuting $n$ data items on a PRAM with $p$
processors. The task is trivial if $n$ additional cells of global memory
are available. Each processor moves $n/p$ items to the additional storage
and then writes these items back in permuted order.

However, if the additional storage is less than $n$, the task gets
more difficult. Because not all items can be backed up, at least some of
them have to be permuted without additional storage. This can be done by
starting with an item $x$ and following the cycle
$x,\pi(x),\pi(\pi(x)),\ldots,x$. At most two items have to be backed up,
no matter how long the cycle is.

We consider three cases, where the permutation is
- fixed.
- a linear function $\pi(x)=ax\bmod n$.
- arbritrary.

For the first case, Aggarwal, Chandra and Snir (1989) give an optimal
solution if $p\leq n^{1-\epsilon}$. However, their algorithm has large
constant factors that make it impractical.

For the second case, an optimal algorithm is given for $p\leq n/\log n$.
This algorithm exploits the regular structure of the cycles for linear
permutations.

For the third case, a family of algorithms $({\cal A}_k)_k$ is given for
$p=n/\log n$. The algorithms show a time-space tradeoff. ${\cal A}_k$
needs time $D\log n\log^{(k)} n$, where $\log^{(k)} n$ denotes $k$ times
application of $\log$ to $n$. The storage requirements for ${\cal A}_k$
are $n$ global bits, $n/\log n$ global memory cells if $k\geq 2$, and
$D\log n/\log^{(k-1)} n$ local memory cells per processor if $k\geq 2$.
We present simulation results that hint that in practice even
${\cal A}_1$ has an acceptable run time.

The most recent "paths" file spit out by pathalias on this site
recently, lists the fastest path between telly and "gatech" (Georgia
Tech) is through becker!ibmcan!mcnc!gatech.

Most of my paths to Internet sites go by the logical and intended manner,
thorugh the site(s) which agree to forward my Internet mail for me one
hop away.

Is Georgia Tech not on the Internet? It's quite well connected, and some
paths that I wouldn't expect (like ann-arbour.mi.us) go through this
quite convoluted path.

Is the ibmcan -> mcnc route of low enough cost to justify stuff routing
there rather than direct to the Intenet?

Any suggestions?

I bought myself a VCR on Boxing Day in Toronto, which I now find may need
some service because on playback the audio's not always that great.  Normally
this isn't something I need to post about, but a number of things strike me
funny:

1) there was no warranty card in the box; there was a description of
   the warranty bearing an American address, but no card to fill in or
   send anyplace
2) the serial number sticker is not in the usual place, nor is it the
   usual form (6 digits preceeded by "A", white-on-black; this one has
   a 5-digit number only, black-on-white)
3) there is no "CSA approved" sticker anyplace on it

This all suggests that the place I bought it sent someone across the border
who bought it, and brought it back here to sell it to someone cheap.

I guess my question is: What can I do to get warranty service, given that I
bought the unit in good faith?  Is the retailer responsible for providing
the full warranty service?  Is he guilty of any crime?  Am I entitled to
anything like a full refund?  What are my options?

Any advice would be appreciated.

"Grey market" really means that you got it from a channel that the manufacturer
wasn't intending - as such, the distributor/retailer *may* be in violation of
contracts with the manufacturer.  Ie: if Fanyo issued an exclusive
sales/service right in Canada to "The Block", and "Peon's" went down
to the USA and bought a truckload from Fanyo directly, and you bought from Peon's.
Since Canadian warrantee service is via The Block, and the equipment was
bought from outside of their exclusive sales channel, The Block has no obligation
to service the equipment.  In such a case, however, The Block may end up suing
Fanyo (for breach of contract) if they could demonstrate that Fanyo knew the
equipment was going to Canada.

[There are other types of "grey market", many of which are actually fraud.
In which case, warrantees aren't going to be honoured by anyone.]

It's difficult to see how they could enforce mandatory manufacturer's warrantee
when the manufacturer is out-of-country.  Nor would imposing the warrantee 
on the licensed service organization be fair anyways.  Seller, I guess,
would have to become liable for whatever's required under the Manufacturer's
warrantee provision (ie: they may have to pay out of their own pockets to
the "proper" service organization to fulfill the warrantee).

On the other hand, there are laws that impose legal minimum warrantees on
the seller.  That is another approach you can take - if you can demonstrate
that the equipment is defective.

Reason 2 makes sense if you had opened the CD and taped it, then returned
it.  In that scenario, you would 1)get a "free" copy of the recording" and
2)violated copyright laws by making an unauthorized recording.  Since the
record store cannot verify that no copies of the CD have been made, they
cannot accept it unless it has a defect.  I think that I would have to 
agree with them that you should have looked at the titles first.

Well, let me get my two cents in on this thread.  I think that if a product has
Underwriter's Lab approval (look for a sticker that says UL instead of CSA) it
is good enough to hook up to your electric system, but, check with your local
electric supplier, as I might not have any idea what I am talking about.  UL
is the CSA of the States (more or less).

"Good enough" ain't good enough.  It is illegal to sell non-CSA-approved
electrically operated equipment in Canada.  This can be made legal if the seller
obtains Hydro-approval (per unit, costs about $75) or from some other organizations
(See Ontario Hydro Electrical Safety Code for details).

CSA is somewhat stricter than UL.

In the States UL is advisory only, and required only indirectly: ie: the NEC
(US electrical code) requires UL compliance in wiring components before wiring
(ie: house wiring) can be approved and occupancy permits issued.

ULC (UL of Canada) approval means nothing legally - ULC is advisory only here.

CSA is not advisory.  CSA compliance/approval is mandatory.

Price Club got charged with this when it was discovered that some of their
off-shore merchandise was unapproved, or, indeed, had false stickers applied
by their suppliers.  If I recall correctly, they got off on most of it because
they could prove that the suppliers falsified compliance documents etcetera
and lied to PC.
