If you use gkrellm, you'll get a plot of each core's activity so it's easy to see how many are being used. yum install gkrellm. HTH On 07/01/2018 06:16 AM, Jeff Newmiller wrote: > Use "top" at the bash prompt. > > Read about the "mc.cores" parameter to mclapply. > > Make a simplified example v

Re: [R] parallel processing in r...

Use "top" at the bash prompt. Read about the "mc.cores" parameter to mclapply. Make a simplified example version of your analysis and post your question in the context of that example [1][2][3]. You will learn about the issues you are dealing with in the process of trimming your problem, and wi

Re: [R] parallel processing in r...

The effectiveness of parallelizing code, be it with mclapply or otherwise, depends in large part on the code, which you failed to show. I cannot answer your other question. Cheers, Bert Bert Gunter "The trouble with having an open mind is that people keep coming along and sticking things into

Re: [R] parallel processing with foreach

It seems you don't quite understand how foreach works. foreach (..) %dopar% { ... } takes the last value from each of the second {...} evaluations and feeds them to the .combine function (in your case rbind()). Since your last call in the %dopar% {...} block is assign(), you are not getting anythin

Hi Rainier, Thanks for your suggestions. I should have been more specific, I am using multiple cores on a Mac Pro running Snow Leopard. I can see where that makes a difference. --David On 4/18/12 12:13 AM, "Rainer M Krug" wrote: -BEGIN PGP SIGNED MESSAGE- Hash: SHA1 On 17/04/12 20

Hi Sandeep, still missing an answer? Perhaps you cross check your post with the rules of the posting guide and find what is missing at all here. Anyway, depending on your OS, package multicore, snow/snowfall may fit your needs - but you have to re-formulate your loop using adequate multicore *appl
