[parallel-package] feature request: set default cluster type via environment variable
...ter| yields an overall better experience /on Linux/ than the |makePSOCKcluster|, for whatever definition of better. Let me just summarize that it works smoother. I believe, other people working with *parallel* on Linux can share this experience Also, we did really welcome the environment variable |MC_CORES|, to be able to specify (in job submit scripts) the amount of CPU cores a user has been granted, most importantly for /dynamic resource requests/ (see below for an example). What we would also appreciate - and now we finally get to the feature request - is another environment variable to choose t...

getOption() versus Sys.getenv
Hi there, I am trying to distinguish between getOption() and Sys.getenv(). My understanding is that these are both used to set values for variables. getOption is set something like this: option("var" = "A"). This can be placed in an .Rprofile or at the top of script. They are called like this getOption("var"). Environmental variables are set in the .Renviron file

SUGGESTION: Settings to disable forked processing in R, e.g. parallel::mclapply()
...ecommended to use PSOCK clusters (`parallel::makeCluster()`) rather than *forked* processes when running R from RStudio ( https://github.com/rstudio/rstudio/issues/2597#issuecomment-482187011). AFAIK, it is not straightforward to disable forked processing in R. One could set environment variable `MC_CORES=1` which will set R option `mc.cores=1` when the parallel package is loaded. Since `mc.cores = getOption("mc.cores", 2L)` is the default for `parallel::mclapply()`, this will cause `mclapply()` to fall back to `lapply()` avoiding _forked_ processing. However, this does not work when th...

RFC: MCA/MCE concept
Hello! The current MCA/MCE support in Xen is that it dumps the error and panics. In the following concept I propose here, there are two places where Xen has to react on. I) Xen receives a MCE from the CPU and II) Xen receives Dom0 instructions via Hypercall The term "self-healing" below is used in the sense of using the most propriate technique(s) to handle an error such as MPR
