Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
Â
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Power Grid Model
The global energy transition is placing new and unprecedented demands on Distribution System Operators (DSOs). Alongside upgrades to grid capacity, processes such as digitization, capacity optimization, and congestion management are becoming vital for delivering reliable services.
Power Grid Model is an open source project from Linux Foundation Energy and provides a calculation engine that is increasingly essential for DSOs. It offers a standards-based foundation enabling real-time power systems analysis, simulations of electrical power grids, and sophisticated what-if analysis. In addition, it enables in-depth studies and analysis of the electrical power grid’s behavior and performance. This comprehensive model incorporates essential factors such as power generation capacity, electrical losses, voltage levels, power flows, and system stability.
Power Grid Model is currently being applied in a wide variety of use cases, including grid planning, expansion, reliability, and congestion studies. It can also help in analyzing the impact of renewable energy integration, assessing the effects of disturbances or faults, and developing strategies for grid control and optimization.
What to expect
For the upcoming meetup we are organizing, we have an exciting lineup of activities planned:
-Insightful presentations covering two practical applications of the Power Grid Model.
-An update on the latest advancements in Power Grid -Model technology during the first and second quarters of 2024.
-An interactive brainstorming session to discuss and propose new feature requests.

The introduction of DLAU and the CCB & CCX licensing model caused quite a stir in the HCL community. As a Notes and Domino customer, you may have faced challenges with unexpected user counts and license costs. You probably have questions on how this new licensing approach works and how to benefit from it. Most importantly, you likely have budget constraints and want to save money where possible. Don’t worry, we can help with all of this!
We’ll show you how to fix common misconfigurations that cause higher-than-expected user counts, and how to identify accounts which you can deactivate to save money. There are also frequent patterns that can cause unnecessary cost, like using a person document instead of a mail-in for shared mailboxes. We’ll provide examples and solutions for those as well. And naturally we’ll explain the new licensing model.
Join HCL Ambassador Marc Thomas in this webinar with a special guest appearance from Franz Walder. It will give you the tools and know-how to stay on top of what is going on with Domino licensing. You will be able lower your cost through an optimized configuration and keep it low going forward.

4. INTRODUCTION
Storing Electrical energy have been the subject of many researches during few past years since
more and more clean, cheap however not very stable renewable energy sources are being
introduced to the market. With a proper storage option the excess energy produced during off-peak
hours can be used for peak shaving thus reducing the total required capacity for the grid. For this
purpose the technologies has been implemented commercially so far, Compressed Air Energy
Storage (CAES). As much as 99% of the world’s storage capacity is done by the former with a total
of 127-129 GW all around the world. The latter technology is implementable in a wide range of
scales which can deliver up to 100MW+ of power per unit. [X. Luo, J. Wang, M. Dooner, J. Clarke,
and C. Krupke, “Overview of current development in compressed air energy storage technology,”
Energy Procedia, vol. 62, pp. 603–611, 2014.] A CAES plant use excessive energy of the grid to run
compressors in order to compress the air and store it in a reservoir. Later on during peak periods the
energy of stored compressed air is returned to the grid using an expander (e.g. a turbine) coupled
with a generator. Other than power-plants which use this technology, developments has been carried
out in order make this type of storage possible in smaller scales for a more distributed solution
5. PROBLEM STATEMENT
Pakistan is facing the worst power crises since last one decade. The major cause is the increase
in electrical demand of three to five times without extra generation plant being added to the
existing pool.
Compressed air energy storage (CAES) is a technique for supplying electric power to meet
peak load requirements of electric utility systems. It incorporates a modified state-of-the-art
gas turbine and an underground reservoir that may be an aquifer, a salt cavity or a mined hard
rock cavern.
6. PROPOSED OBJECTIVES
The objective of this research is to:
Design, developed and Analysis of a small scale compressed air energy storage
prototype for a small home as an un-interrupted power supply system.
7. The system is composite technology, which composes of energy storage system and electric
power supply system. the principle is based on compressing and storage of air during the hours
when electricity is available from the grid supply and using the stored energy to generate
electricity by means of a turbine-generator system during the hours of load shedding. the
essential components of the entire system consists of a source to make compress air and storage
cylinders. the output of the storage cylinders is coupled to the turbine through valve and regulator.
the turbine is coupled to the generator. regulated air form the compressed air cylinder is allowed
to flow to the turbine system by opening of a valve either operated manually or automatically
during the time when the supply is interrupted from the grid mains.
PROPOSED METHODOLOGY
8. In the present work, the idea is to use the concept of renewable energy resources such as solar
and wind. the energy will transfer from the renewable energy resource (solar plant) to the CAES
system drives the air compressor engine to produce high-pressure compressed air to be stored in
cylinders. CAES is used on demand or used in during the peak periods or when the solar energy
is not available to generate power by a special wind turbine coupled with generator as shown in
figure (1).
