Hi all,I am working in a multi core machine and I am trying to make some
parallel code to speed up the process.
I have seen already the foreach packet but it looks like that it always combine
the results on a list. My case though is simpler since I am plotting and saving
in external files, inside the loop, and thus I do not need to keep anything
from the loop.My code looks like
expandMeanSigmaOn<-expand.grid(1:100,100:200,5:10,5000:6000)
for (i in 1:length(expandMeanSigmaOn$Var1)){
mean1<-expandMeanSigmaOn$Var1[i]
mean2<-expandMeanSigmaOn$Var2[i]
sd1<-expandMeanSigmaOn$Var3[i]
sd2<-expandMeanSigmaOn$Var4[i]
fitcass1<-mix(mydata,mixparam(c(mean1,mean2),(c(sd1,sd2)),"gamma")))
pdf(file=paste(filename,"ON.pdf",sep=""));plot(fitcass1);dev.off() # plotting
and saving
save(OnFitList,file=paste(filename,"ON.Rdata",sep="")) # plotting and saving
}
}
}
as you can see from the code above, given some input values I am trying some
fits, which then I am saving the results. Do you think that the foreach
packaget would be suitable (since the returning list can grow very large and
eat up memory) or should I try some alternative package?
I would like to thank you in advance for your replyRegardsAlex
