Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
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).

zkStudyClub - LatticeFold: A Lattice-based Folding Scheme and its Application...Alex Pruden
Folding is a recent technique for building efficient recursive SNARKs. Several elegant folding protocols have been proposed, such as Nova, Supernova, Hypernova, Protostar, and others. However, all of them rely on an additively homomorphic commitment scheme based on discrete log, and are therefore not post-quantum secure. In this work we present LatticeFold, the first lattice-based folding protocol based on the Module SIS problem. This folding protocol naturally leads to an efficient recursive lattice-based SNARK and an efficient PCD scheme. LatticeFold supports folding low-degree relations, such as R1CS, as well as high-degree relations, such as CCS. The key challenge is to construct a secure folding protocol that works with the Ajtai commitment scheme. The difficulty, is ensuring that extracted witnesses are low norm through many rounds of folding. We present a novel technique using the sumcheck protocol to ensure that extracted witnesses are always low norm no matter how many rounds of folding are used. Our evaluation of the final proof system suggests that it is as performant as Hypernova, while providing post-quantum security.

A simple hand-operated slicer that can slice
bamboo splits in thick slivers used in manufacturing
fine basketry and novelty items.
This die consists of four tools having a
length of 40 mm height of 25 mm and the end
thickness of 2.5mm. These tools are placed parallel
to each other and having a clearance of 2 mm so that
we get the slices of about 1.5 mm. These tolls are
fitted between two flat plates having a thickness of 4
mm. The splitted bamboo pieces are forced by using
hydraulic force on to the slicing cutters in such a

four pieces of 1.5 mm to 2 mm. The actual slicing
die and CAD model of the same is also showed in

A number of experiments were conducted Fig 7: Slicing Die
to study the effects of various machining parameters
on bamboo processing operations. These studies
have been undertaken to investigate the effects of
various sizes of bamboo, speed, cutters and other
machine parameters on torque, energy and time
required in processing operations. During
experimentation various variety and sizes of
bamboo samples are collected and processed at three
different speeds. For splitting operation different
diameter of bamboos were taken in to consideration
for obtaining cutting force required to split bamboos
of different diameters. The result of the same is
shown below. In the next step the already spllited
bamboo pieces are forced on to the slicing tool and
it gets sliced in four pieces, the actual slices are also
shown in figure no 8. Fig 8 : Bamboo Slices alongwith slicing die.
Conclusion:-
After conducting a number of experiments on
different dies for producing slices from bamboo
splits, we estimated the power required to produce
slices from different dies, the quality of slices and
time required to produce slices out of each split
