A distributed lock manager (DLM) provides distributed software applications with a means to synchronize their accesses to shared resources.

A distributed lock manager (DLM) provides distributed software applications with a means to synchronize their accesses to shared resources.

DLMs have been used as the foundation for several successful clustered file systems, in which the machines in a cluster can use each other's storage via a unified file system, with significant advantages for performance and availability. The main performance benefit comes from solving the problem of disk cache coherency between participating computers. The DLM is used not only for file locking but also for coordination of all disk access.

Multivariate State Space model in r (dlmodeler)

I'm trying to fit a multivariate dlm using the dlmodeler package. The model is a state space representation of a simplified macroeconomic model, as such: Observation equations: h(t) = c + A * h(t-1) + B * r(t) - B *rs(t) + err1(t) pi(t) = C *…

How to implement special cases of state space models in dlm? Or how to obtain a Kalman-smoother from the FKF package?

I am trying to estimate a state-space model to obtain the potential output (y_p) from data on output (y) and the unemployment rate (u) using R. The model is already programmed in EViews and I simply want to reproduce its results. The model is…

state space using package DLM and FKF

The state space model I am trying to implement is as follows: $ y_t= CY + FF* X_t + Ve_t$ $(X_t-m0)= GG (X_{t-1}-m0) +W\eta_t$ In DLM I am using following modification (because DLM does not allow intercept in measurement and transition…
