{{TOCrightEx}}==Background=====Transactional memory===*Transactional memory is a general and flexible way to allow programs to read and modify disparate primary memory locations atomically as a single operation, much as a database transaction can atomically modify many records on disk.*[http://en.wikipedia.org/wiki/Transactional_memory Transactional memory] attempts to simplify parallel programming by allowing a group of load and store instructions to execute in an atomic way. Transactional memory is a concurrency control mechanism analogous to database transactions for controlling access to shared memory in concurrent computing. A transaction is a piece of code that executes a series of reads and writes to shared memory.*Transactional memory (TM) supports code sections that are executed atomically, i.e., so that they appear to be executed one at a time, with no interleaving between their steps. TM significantly reduces the difficulty of writing correct concurrent programs. A good TM implementation avoids synchronization between concurrently executed transactional sections unless they actually conflict. TM can significantly improve the performance and scalability of concurrent programs, as well as makes them easier to write, understand and maintain.*[http://appft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PG01&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.html&r=1&f=G&l=50&s1=%2220070156994%22.PGNR.&OS=DN/20070156994&RS=DN/20070156994 Transactional memory] generally refers to a synchronization model that allows multiple threads to concurrently access a shared resource (such as a data structure stored in memory) without acquiring a lock as long as the accesses are non-conflicting, for example, as long as the accesses are directed to different portions of the shared resource.

===Transactional programming models===*[http://research.sun.com/spotlight/2007/2007-08-13_transactional_memory.html Transactional programming models] can be supported in software using software-based transactional memory (STM), in hardware using hardware- based transactional memory (HTM), or in a combination of the two (Hybrid TM, or HyTM).**[Diabetes Overviewhttp://en.wikipedia.org/wiki/Software_transactional_memory Software based Transactional memory](STM) can allow sequences of concurrent operations to be combined into atomic transactions, thereby reducing the complexity of both programming and verification. STM is a scheme for concurrent programming with multiple threads that uses transactions similar to those used in databases.**Hardware based Transactional memory (HTM) system requires no read or write barriers within the transaction code. The hardware manages data versions and tracks conflicts transparently.**[http://www.eecs.harvard.edu/~fedorova/papers/asplos165-damron.pdf Hybrid Transactional memory]==(HyTM) implements Transactional memory in software so that it can use best-effort Hardware Transactional memory (HTM) to boost performance but does not depend on HTM.

===Maintaining a healthy weight is a challenge for most Americans=Dynamic STM (DSTM)====*66[http://research.3% of the adult population in the US weigh more than sun.com/scalable/pubs/PODC03.pdf Dynamic Software Transactional Memory (DSTM)] is healthy Where you carry your fat a low-level application programming interface (API) for syn-chronizing shared data without using locks.*DSTM supports dynamic-sized data structures. DSTM has non-blocking implementation. The non-blocking property is importantobstruction-freedom. Fat in Dynamic means that the mid-section – visceral fat – set of locations accessed by the transaction is worse, as this fat surrounds not known in advance and invades vital organsis determined during its execution. Few Americans add muscle and bone after their early twenties so nearly all added weight is fat* Daily caloric intake is the number of calories needed per day DSTM techniques allow transactions and transactional objects to maintain your current weightbe created dynamically. Maintaining a healthy weight is a balancing act Transactions may determine the sequence of calories consumed versus calories burnedWeight change = calories objects to access based on the values observed in – calories out* Small increases objects accessed earlier in daily caloric intake cause increases in body fat mass (Figure 1)[[Image:Maintaining_a_healthy_weight_is_a_challenge_for_most_Americans_01the same transaction.png|Figure 1.

DSTM2 significantly improves the programming interface of its predecessor DSTM. The code is provided in Java libraries and any Java programmer can use it easily. DSTM2 allows researchers to plug in their STM implementations and directly compare them with others.*The DSTM2 library assumes that multiple concurrent threads share data objects. The DSTM2 library provides a new kind of thread that can execute transactions, which access shared atomic objects. DSTM2 threads provide methods for creating new atomic classes and executing transactions.
====Nonblocking Software Transactional Memory====* Today, adult men and adult women are almost 25 pounds heavier than 40 years ago (Figure 2)[http://research.

===Hardware based Transactional memory===*HTM comprises hardware transactions implemented entirely in processor hardware. For hardware transactions, data may be stored in hardware registers and cache, such that all cache actions are done atomically in hardware and data in the HTM is only written to the main memory upon committing the transaction. The HTM holds all the speculative writes without propagating to the main system memory, such as a Random Access Memory (RAM) device, until the transaction commits. If the hardware transaction aborts, then the cache lines holding the tentative writes in the HTM are discarded. HTM hardware transactions may utilize cache coherency protocols to detect and manage conflicts between HTM hardware transactions. The cache coherency protocols keep track of accesses within a hardware transaction. If two hardware transactions are accessing a same memory location, then the HTM aborts one transaction if there is a conflict, else the transaction's changes may be committed to the system memory.*HTM transactions usually require less overhead then STM transactions because HTM transactions occur entirely in hardware. HTM transactions may be limited to smaller transactions due to hardware limitations, whereas STM transactions can handle large and longer transactions. [http://appft1.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PG01&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.html&r=1&f=G&l=50&s1=%2220070143287%22.PGNR.&OS=DN/20070143287&RS=DN/20070143287 Source]*The multi-core processor ''There 'Rock''' supports [http://research.sun.com/scalable/pubs/TRANSACT2008-ATMTP-Apps.pdf Hardware Transactional Memory] (HTM).*'''Rock'''’s HTM feature is an important but modest first step in integrating HTM support into a progression from normal blood sugar to type 2 diabetesmainstream commercial multi-core processor.*'''Rock''' supports HTM with two new instructions, chkpt and commit, and a new checkpoint status (cps) register.

====Best-effort Hardware Transactional Memory====
*Best-effort Hardware Transactional Memory transactions are committed in-cache and aborted if they don’t fit. Best-effort Hardware Transactional Memory has simple design.Best-effort Hardware Transactional Memory violates Principle of Least Astonishment. Programmer should not have to think about cache mapping, cache size, cache organization, etc.
*[http://research.sun.com/scalable/pubs/TRANSACT2008-ATMTP-Apps.pdf Best-effort HTM] does not guarantee to support transactions of any size and duration, and thus is free to simply abort transactions that exceed on-chip resources for HTM or encounter difficult events or situations.

Caches observe all reads and writes issued by a processor, can buffer a significant amount of data, and can be searched efficiently because of their associative organization. All HTMs modify the first-forlevel caches, but the approach extends to higher-diabeteslevel caches, both private and shared.*Conflict detection occurs as other processors receive the coherence messages from the committing transaction. Hardware looks up the received block address in the local caches. If the block is in a cache and has its R or W bit set, there is a read-write or a write-write conflict between the committing and the local transaction. The hardware signals a software handler, which aborts the local transaction and potentially retries it after a backoff period.*'''Direct memory updates:''' For direct updates, the hardware transparently logs the original value in a memory block before its first modification by a transaction.

The basic building block of a carbohydrate also to provide the ability to execute transactions using whatever HTM support is available in such a sugar molecule, a simple union way that the two types of carbon, hydrogen, and oxygentransactions can coexist correctly. Starches *The key idea to achieving correct interaction between software transactions and fibers are essentially chains of sugar moleculeshardware transactions is to augment hardware transactions with additional code that ensures that the transaction does not commit if it conflicts with an ongoing software transaction.
Carbohydrates were grouped into two main categories:====Phased Transactional Memory (PhTM)====* Simple carbohydrates included sugars such as fruit sugar [http://research.sun.com/scalable/pubs/TRANSACT2007-PhTM.pdf Phased Transactional Memory (fructosePhTM])supports switching between different “phases”, corn or grape sugar (dextrose or glucose), and table sugar (sucrose)each implemented by a different form of transactional memory support. * Complex carbohydrates included everything made PhTM allows to adapt between a variety of three or more linked sugarsdifferent transactional memory implementations.

NZTM can execute transactions using best-effort hardware transactional memory or by using compatible software transactional memory system.
Foods contain three major types of nutrients====[http: carbohydrates //research.microsoft.com/~larus/Papers/p80-larus.pdf Hardware-Accelerated STM (carbsHASTM), proteins and fats]====*Hardware-Accelerated STM (HASTM) system proposes hardware support to reduce the overhead of STM instrumentation. Carbohydrate foods most often come from plants, such as fruits, vegetables The supplementary hardware allows software to build fast filters that could accelerate the common case of read set maintenance.*HASTM provides the STM with two capabilities through per-thread mark bits at the granularity of cache blocks. *'''Conflict detection:''' Software can check if a mark bit was previously set for a given block of memory and grainsthat no other thread wrote to the block since it was marked. Carbohydrates are chains *'''Validation:''' Software can query if potentially there were writes by other threads to any of sugar molecules; thus, they have the greatest effect on blood-sugar levels when these chains are digested (broken down)memory blocks that the thread marked.
Complex carbohydrates are longer chains of sugars====[http://research.

A hardware Bloom filter outside of the caches computes the signatures.b Software instrumentation provides the filters with the addresses of the objects read or written within a transaction. To detect conflicts, hardware in the computer monitors coherence traffic for requests for exclusive accesses to a cache block, which indicates a memory update. [[image:carbohydrates types*The hardware tests if the address in a request is potentially in a transaction’s read or write set by examining the transaction’s signatures. If so, the memory reference is a potential conflict and the STM can either abort a transaction or turn to software validation.jpeg|center|thumbs|800 px]]
====Carbohydrates and the Glycemic Index====A new system for classifying carbohydrates known as the glycemic index, measures how fast and how far blood sugar rises after you eat a food that contains carbohydrates----
White bread, for example, is converted almost immediately to blood sugar, causing it to spike rapidly. It's classified as having a high glycemic index. Brown rice, in contrast, is digested more slowly, causing a lower and more gentle change in blood sugar. It has a low glycemic index.
Diets filled with high-glycemic-index foods, which cause quick and strong increases in blood sugar levels, have been linked to an increased risk for both diabetes and heart disease. [http://www.hsph.harvard.edu/nutritionsource/carbohydrates.html Source]

The glycemic index measures how fast a food is likely to raise your blood sugar. This can be helpfu. For example, if your blood sugar is low and continuing to drop during exercise, you would prefer to eat a carb that will raise your blood sugar quickly. On the other hand, if you would like to keep your blood sugar from dropping during a few hours of mild activity, you may prefer to eat a carb that has a lower glycemic index and longer action time. If your blood sugar tends to spike after breakfast, you may want to select a cereal that has a lower glycemic index.----

* Fiber content. Fiber shields the starchy carbohydrates in food immediate and rapid attack by digestive enzymes. This slows the release of sugar molecules into the bloodstream.* Ripeness. Ripe fruits and vegetables tend to have more sugar than unripe ones, and so tend to have a higher glycemic index.* Type of starch. Starch comes in many different configurations. Some are easier to break into sugar molecules than others. The starch in potatoes, for example, is digested and absorbed into the bloodstream relatively quickly.* Fat content and acid content. The more fat or acid a food contains, the slower its carbohydrates are converted to sugar and absorbed into the bloodstream.* Physical form. Finely ground grain is more rapidly digested, and so has a higher glycemic index, than more coarsely ground grain.----

The long-held belief that eating foods containing "sugar" (sweets) will cause your blood glucose levels to rise higher and more quickly than starchy foods (bread, rice, pasta, etc.) has not been supported by scientific evidence. Both are forms of carbohydrates and both cause blood glucose to increase.---
Research has shown that your total daily amount of carbohydrate intake affects your blood glucose levels. Carbohydrates have the most immediate effect on blood glucose levels, since carbohydrates are broken down into glucose ==Key companies==* Intel(sugar26 patents) early during digestionand Sun Microsystems (19 patents) are major players. It is important to eat the suggested amount of carbohydrate at each meal, along with some protein, * Microsoft(11 patents) and fatIBM(7 patents) are next to them.
Carbohydrates are mainly found in three food groups[[Image: Fruit; Milk and Yogurt; and Bread, Cereal, Rice, Pasta and Starchy Vegetables. You will need to consider the total amount of carbohydrates when working out your daily meal planAssignee_graph-Transactional_memory. jpg|align|thumb|center|500px|Top Assignees]]
'''Carbohydrate counting'''Counting grams of carbohydrate and evenly distributing them at meals will help you manage your blood glucose. Carbohydrate counting is a method of meal planning that is a simple way to keep track of the amount of total carbohydrate you eat each day. Instead of following an exchange list, you monitor how much carbohydrate (sugars and starches) you eat daily. One carbohydrate choice is equal to 15 grams of carbohydrate. Note: your consumption of protein and fat still counts as calories.----
With carbohydrate counting==Top IPC and US Classes==*'''Top IPC class:''' G06F*'''Top US class:''' 711, you can pick up almost any food product off the shelf707, read the label712, and use the information about grams of carbohydrate to fit the food into your meal plan.717, 718
Carbohydrate counting is most useful for people who take multiple daily injections of insulin, use an insulin pump, or who want more flexibility and variety in their food choices[[Image:IPC_class-Transactional_memory. The amount and type of insulin you are prescribed may affect the flexibility of your meal planjpg|align|thumb|left|500px|IPC class]][[Image:US_class-Transactional_memory.jpg|align|thumb|right|500px|US class]]
A registered dietitian can help you determine how much carbohydrate, as well as other foods, you should include in your daily meal plan.
Carbohydrate counting may not be for everyone, and the traditional method of following food exchange lists may be used instead.----

The initial binding of insulin to its receptor initiates Transactions are executed using local shared transactional memory, such as a signal transduction cascade that communicates the message delivered by insulin: remove glucose from blood plasma (see panel 3)cache memory. Among Upon overflowing the wide array of cellular responses resulting from insulin ‘activationshared transactional memory,the key step in glucose metabolism transactional memory is the immediate activation virtualized and increased levels of GLUT4 glucose transporters. By the facilitative transport of glucose /or extended into the cells, the glucose transporters effectively remove glucose from the blood stream. Insulin binding results in changes in the activities and concentrations of intracellular enzymes such as GLUT4. These changes can last from minutes to hours. As important as insulin is to preventing too high of a blood glucose higher-levelmemory, it is just such as important that there not be too much insulin and hypoglycemia. As one step in monitoring insulin levels, the enzyme insulinase (found in the liver and kidneys) breaks down blood-circulating insulin resulting in a half-life of about six minutes for the hormone. This degradative process ensures that levels of circulating insulin are modulated and that blood glucose levels do not get dangerously lowsystem memory.[[image:image12.jpeg|-|align = "center" bgcolor = "#969696"|700 px|thumb]]<font color="#00FFFF">9</font>Insulin binding to the insulin receptor induces a signal transduction cascade which allows the glucose transporter (GLUT4) to transport glucose into the cell|align = "center"|<font color="#0000FF"><u>[http://appft1uspto.gov/netacgi/nph-Parser?Sect1=PTO2&Sect2= Analysis of Oreo cookies HITOFF&u=%2Fnetahtml%2FPTO%2Fsearch-adv.html&r=1&f=G&l=50&d=Key ingredient of Oreo cookiesPG01&p=1&S1=20080098374.PGNR.&OS=DN/20080098374&RS=DN/20080098374 US20080098374A1]</u></font>Identifies |Method and apparatus for performing dynamic optimization for software transactional memory|align = "center"|Dynamic STM (DSTM)|The present invention relates to a method and apparatus for performing dynamic optimization for STM.
