 +====== Concurrent Applications using Elastic Transactions ======
 +**Master project**
 +In an attempt to make the programming abstraction as general as possible, Software Transactional Memory (STM) often hampers performance. In contrast with STMs, synchronization techniques at the core of a concurrent program that targets a single specific application can be genuinely tuned to enhance concurrency and to 
 +limit contention. ​
 +Elastic transactions is a variant of the transactional model.
 +Upon conflict detection, an elastic transaction might drop what it did so far within
 +a separate transaction that immediately commits, and initiate a new transaction which might 
 +itself be elastic. Elastic transactions are a complementary alternative to traditional ​
 +transactions,​ particularly appealing when implementing search structures. Both forms of transactions can
 +safely be combined within the same application.
 +The goal of the project is to implement a real concurrent application using [[http://​lpd.epfl.ch/​gramoli/​php/​estm.php|E-STM]],​ an STM implementing elastic and regular transactions,​ to enhance concurrency. The task is 
 +  * to propose some applications, ​
 +  * to implement some of them using the transaction API, 
 +  * to extend [[http://​lpd.epfl.ch/​gramoli/​php/​estm.php|E-STM]] with nesting of elastic transactions inside normal ones, and
 +  * to experiment them on a multicore machine.
