Code Optimization in the Polyhedron Model - Improving the Efficiency of Parallel Loop NestsA safe basis for automatic loop parallelization is the polyhedron model, which represents the iteration domain of a loop nest as a polyhedron in an n dimensional integer lattice. However, turning the parallel loop program in the model to efficient code meets with several obstacles, due to which performance may deteriorate seriously especially on distributed memory architectures. This thesis introduces a fine grained model of the computation performed
A safe basis for automatic loop parallelization is the polyhedron model, which represents the iteration domain of a loop nest as a polyhedron in an n-dimensional integer lattice. However, turning the parallel loop program in the model to efficient code meets with several obstacles, due to which performance may deteriorate seriously - especially on distributed memory architectures. This thesis introduces a fine-grained model of the computation performed and shows how this model can be applied to create efficient code.

THE favorite toy
Size: 1 Count (Pack of 1), Style: Shark, Size: 1 Count (Pack of 1), Style: Shark
I found this toy used at a thrift store almost 1 year ago. My Shih tzu mix loved it so much till all the seams ripped out and 2 out of 3 squeekers fell out and it was shambles, hardly usable at all. 1 week ago I decided to try my luck to find a similar shark toy for Finnegan. I couldn't believe my eyes when I found THE EXACT same toy!! When I unboxed it, I put the old and new side-by-side and imagine his surprise, it was priceless! Very pleased with this.

Best Dog Toy Ever!
Size: Small (Pack of 1), Style: Monkey, Size: Small (Pack of 1), Style: Monkey
Unbelievable. See below previous reviews. Today is 3/22/2023 (4th Update): Cavachon is now three years old. THIS MONKEY is STILL played with DAILY. She’s played with and lost interest in dozens of other toys in the past three years, but Monkey is always the go-to. Now only on Monkey #6, which is remarkable considering the daily torture she puts Monkey through. Other toys get destroyed, but Monkey endures. This toy is our dog’s best friend and playmate!
10/9/21 (3rd update): Its rare that any toy (without food inside) keeps the interest of our Cavachon for even 30 minutes… yet day after day, she runs around with Monkey for at least an hour. She’s on her 4th Monkey… and this thing gets mauled, chewed, super-squeaked, fetched, and shook violently EVERY DAY. Durability times ten!
2/21/21 (2nd Update): Crazy pup is now 14 months old, and she plays DAILY with “monkey”! She’s on her third monkey because eventually she pulls off the tail, but each of her first two lasted months.
ORIGINAL REVIEW MAY 2020: There is something really special about this monkey... Our 5-month-old Cavachon LOVES this toy. I recently ordered a second one, in case she wears out the first one. She knows it’s her “monkey” and finds it when we ask her “Where’s monkey?” She fetches it, walks around squeaking it, and she also zooms around the house shaking it furiously by the tail. She’s been playing with, and chewing on all parts of It, DAILY for three months. In the photo, you can compare the brand-new one, still on the cardboard, with the one she’s mauled for three months. Not much difference. I would say this is an extremely durable, and safe, toy.

Nice design, pay attention to the size specification
Size: Small (Pack of 1), Style: Monkey
Nice toy with minimal appendages - meaning that body parts are not quickly chewed off. I made the mistake of getting this one along with one for the Large dog. This monkey is intended to be a small dog toy and as soon as I felt it, I knew my English Shepherd of 8 months would probably have it torn up within a day or two.
I really like the design - no ropes or braids or legs, no small pieces for the eyes, etc. The monkey does have a small curly-Q tail but so far it's stayed attached to the monkey. It's durability has surprised me so far.
For years I have had a Jack Russell terrier, which I think might be considered a small/medium dog (at least mine was). This toy would have lasted him weeks or even months, he didn't set out to eat his toys. Now I have an English Shepherd and I forget that she's probably considered a large dog. She rarely chews up anything EXCEPT her toys, but when she gets a new toy, she spends hours "getting to know it" and she's got pretty sharp teeth.
The fabric on this toy is durable, not easily torn. Because there is no stuffing the squeaker is easy for the dog to squeak - and if your dog hasn't had squeaky toys before, that might freak them out just a little, it did my dog, she started off apprehensive of the toy but quickly grew to enjoy it.
Because this toy is hollow and not dense, my dog doesn't chew on it the same way as she did her rope-style toy, and therefore this toy has lasted longer than the KONG Pudge Braidz Pig Dog Toy, Medium/Large toy (which lasted about 10 minutes). Someone else here posted some good pictures of their larger sized dog with this toy, and that dog looks to be about the same size as mine. That person stated the toy didn't last long and showed pictures of how it looked after being dismantled. I expect that to happen to this one since that dog's size is similar to mine, although it's lasted so far more than a day. I guess it partially depends on not just the toy but the dog, too. Because there's no density to this toy, my dog doesn't seem to want to chew it like she does a bone, instead she tosses and wrestles it, occasionally making it squeak, then lies down next to it and takes a nap.
All in all, this is so far, my favorite dog toy brand. It's less dangerous than the Kong toys or the Nylabone toys, and especially less dangerous than the rope style toys. I purchased several other Petstages toys and so far, they have lasted longer than any other brand, including those named. I just should have been more attentive to the recommended dog size, as this toy is clearly not ideal for large dogs. The Petstages Gator toy is better for a large dog. I have also purchased that one and find it much more suitable.

Could be made much stronger & better
Size: Small (Pack of 1), Style: Monkey
Only 3 stars because the long fur is nasty and dogs chew it and it comes off … choking hazard. I trim it when I get them. The fabric is to easily tear doednt last long they should make this much stronger. I’ve bought 4 of these and about to buy 2 more my dogs love them.
