Patent number: 9781027Abstract: Various systems and methods to facilitate general communication, via a memory network, between compute elements and external destinations, while at the same time facilitating low latency communication between compute elements and memory modules storing data sets, without impacting negatively the latency of the communication between the compute elements and the memory modules. General communication messages between compute nodes and a gateway compute node are facilitated with a first communication protocol adapted for low latency transmissions. Such general communication messages are then transmitted to external destinations with a second communication protocol that is adapted for the general communication network and which may or may not be low latency, but such that the low latency between the compute elements and the memory modules is not negatively impacted. The memory modules may be based on RAM or DRAM or another structure allowing low latency access by the compute elements.Type: GrantFiled: April 2, 2015Date of Patent: October 3, 2017Assignee: Parallel Machines Ltd.Inventors: Avner Braverman, Ofir Shalvi, Lior Khermosh, Ofer Bar-Or, Eyal Benjamin Raz Oren, Gal Zuckerman

Patent number: 9690713Abstract: Various systems and methods to use a plurality of linked lists for keeping track of changes to be made in data sets currently in a flash memory. To enhance efficiency of the system, the changes to be made in any particular data set are aggregated in a random access memory (“RAM”) until a sufficient volume of changes have been aggregated to justify a rewrite of the flash memory block in which the particular data set is stored. Since a flash memory may have millions of memory blocks and data sets, there are potentially tremendous demands on the memory resources of the RAM to keep track of all the changes, but the problem presented by these potential demands is avoided through the use of linked lists, in which each list links all of the changes that have been aggregated in RAM and that apply to one specific data set.Type: GrantFiled: April 19, 2015Date of Patent: June 27, 2017Assignee: Parallel Machines Ltd.Inventors: Lior Khermosh, Ofer Bar-Or, Gal Zuckerman
