detecting operating system in R (e.g. for adaptive .Rprofile files) -


i wondering how automatically detect operating system in r, example place things in .rprofile.

i'm not sure using sys.info() since page says not implemented on r platforms; maybe use .platform instead? ?.platform has lot of useful information, since:

‘.platform’ list details of platform under r built. provides means write os-portable r code.

it seems packages included r use .platform much more sys.info.

josh: /c/r/r-2.12.0-src/src/library > grep ".platform" */r/* | wc -l 144 josh: /c/r/r-2.12.0-src/src/library > grep ".platform\$os.type" */r/* | wc -l 99 josh: /c/r/r-2.12.0-src/src/library > grep "sys.info" */r/* | wc -l 4

What is happening when Matlab is starting a "parallel pool"? -

running parallel cpu processes in matlab starts command parpool() according documentation , function: [creates] special job on pool of workers, , [connects] matlab client parallel pool. this function takes bit of time execute, on order of 30 seconds. in other multi-cpu paradigms openmp, parallel execution seems totally transparent -- i've never noticed behavior analogous matlab (granted i'm not experienced parallel programming). so, happening between time parpool() called , when finishes executing? takes long? parallel computing toolbox enables run matlab code in parallel using several different paradigms (e.g. jobs , tasks, parfor , spmd , parfeval , batch processing), , run either locally (parallelised across cores in local machine) or remotely (parallelised across machines in cluster - either 1 own, or 1 in cloud). in of these cases, code run on matlab workers , copies of matlab without interactive desktop. if you're intending run on remo...
