Edge to Cloud Tools: A Multivocal Literature Review

Edge-to-cloud computing is an emerging paradigm for distributing computational tasks between edge devices and cloud resources. Different approaches for orchestration, offloading, and many more purposes have been introduced in research. However, it is still not clear what has been implemented in the industry. This work aims to merge this gap by mapping the existing knowledge on edge-to-cloud tools by providing an overview of the current state of research in this area and identifying research gaps and challenges. For this purpose, we conducted a Multivocal Literature Review (MLR) by analyzing 40 tools from 1073 primary studies (220 PS from the white literature and 853 PS from the gray literature). We categorized the tools based on their characteristics and targeted environments. Overall, this systematic mapping study provides a comprehensive overview of edge-to-cloud tools and highlights several opportunities for researchers and practitioners for future research in this area.

Electroweak $SU(2)_L \times U(1)_Y$ model with strong spontaneously fermion-mass-generating gauge dynamics

Higgs sector of the Standard model (SM) is replaced by quantum flavor dynamics (QFD), the gauged flavor $SU(3)_f$ symmetry with scale $Λ$. Anomaly freedom requires addition of three $ν_R$. The approximate QFD Schwinger-Dyson equation for the Euclidean infrared fermion self-energies $Σ_f(p^2)$ has the spontaneous-chiral-symmetry-breaking solutions ideal for seesaw: (1) $Σ_f(p^2)=M_{fR}^2/p$ where three Majorana masses $M_{fR}$ of $ν_{fR}$ are of order $Λ$. (2) $Σ_f(p^2)=m_f^2/p$ where three Dirac masses $m_f=m_{(0)}1+m_{(3)}λ_3+m_{(8)}λ_8$ of SM fermions are {\it exponentially suppressed w.r.t. $Λ$}, and {\it degenerate for all SM fermions in $f$}. (1) $M_{fR}$ break $SU(3)_f$ symmetry completely; $m_{(3)},m_{(8)}$ superimpose the tiny breaking to $U(1) \times U(1)$. All flavor gluons thus acquire self-consistently the masses $\sim Λ$. (2) All $m_f$ break the electroweak $SU(2)_L \times U(1)_Y$ to $U(1)_{em}$. Symmetry partners of the composite Nambu-Goldstone bosons are the genuine Higgs particles: (1) Three $ν_{R}$-composed Higgses $χ_i$ with masses $\sim Λ$. (2) Two new SM-fermion-composed Higgses $h_3, h_8$ with masses $\sim m_{(3)}, m_{(8)}$, respectively. (3) The SM-like SM-fermion-composed Higgs $h$ with mass $\sim m_{(0)}$, the effective Fermi scale. $Σ_f(p^2)$-dependent vertices in the electroweak Ward-Takahashi identities imply: The axial-vector ones give rise to the $W$ and $Z$ masses at Fermi scale. The polar-vector ones give rise to the fermion mass splitting in $f$. At the present exploratory stage the splitting comes out unrealistic.

Towards computing the lepton and quark mass spectra and their consequences

We demonstrate that the chiral gauge flavor $SU(3)_f$ dynamics spontaneously generates the chiral symmetry breaking fermion self energies $Σ(p^2)$ resulting in wide and wild spectra of lepton and quark masses. The Goldstone theorem then necessarily implies: (1) Gauge bosons of gauged chiral symmetries absorb the underlying 'would-be' Nambu-Goldstone (NG) bosons and become massive. Masses are determined by $Σ(p^2)$s of those fermions to which they couple, and by the corresponding gauge coupling constants. (2) Charges of anomalous Abelian chiral fermion currents create composite mixed-parity pseudo NG bosons with calculable couplings to fermions and gauge bosons: (i) the Higgs-looking $h$ with mass due to the $SU(3)_f$ instanton; (ii) the Weinberg-Wilczek axion $a$ with mass due to the QCD instanton; (iii) the Anselm-Uraltsev arion $b$ with mass due to the electroweak instanton. (3) There are the true composite NG bosons, the majorons.
