I started this page today, as I think it deserves a page. IMHO, and it is shared by at least some others, the Mathematica page has often been used as an advertising medium for Wolfram Research, with anything not in the interest of Wolfram Research often removed. Let's try not to do this here. Let us try to keep it neutral. I'm not a user of this product, so perhaps someone with more knowledge can add some examples. It could probably do with being put into the same format as other software, showing version, developer etc. I might do that if I have time. Drkirkby 08:17, 8 October 2007 (UTC)Reply

The product is called gridMathematica with a lower case 'g' at the start. It would seem most logical for the Wikipedia page to be spelt like this, but my attempts to create the page always resulted in the first letter being changed to a capital G. Drkirkby 08:17, 8 October 2007 (UTC)Reply

I created a page on gridMathematica. I'm not a user (yet), so are not an expert. Someone else can perhaps improve it, but I've made a start. Keep it NPOV - the Mathematica does tend to be rather propmotional.

There is an interesting point at the top of this talk page by ChrisChiasson when he complianed about the "vaguely promotional tone" He later went on to say: "I am not an impartial entity with respect to WRI. That is why I haven't edited the article.~"

There is some logic to that. It would tend to avoid the sort of pro-Wolfram bias the Mathematica article suffers at times. But I can see that those with the best knowledge of the product are likely to work for Wolfram Reserach. This is I guess even more true of gridMathematica than the normal version. But if someone from Wolfram Reserach wants to edit it, try to keep it neutral. Drkirkby 12:35, 10 October 2007 (UTC)Reply

You didn't source it. Were you planning to? If no one does, your gridMathematica article is highly vulnerable to nomination for deletion. --Pleasantville 13:20, 10 October 2007 (UTC)Reply

No, I was not planning to, as I was not aware of this! Can you explain more? Drkirkby 13:40, 10 October 2007 (UTC)Reply

Articles about people, products, or companies that are not referenced to what Wikipedia calls a "reliable source" often get tagged either for what's called "speedy deletion" or get tagged as being unsourced, which can lead toward deletion. This is somewhat random in that whether this happens depends on the disposition of Wikipedians stumbling upon the article. This is part of Wikipedia's immune system to keep people and companies from using WIkipedia for self-promotion. --Pleasantville 13:49, 10 October 2007 (UTC)Reply

I'll see what I can dig up. --208.54.95.163 14:48, 10 October 2007 (UTC)Reply

OK. I've added a few references, but I didn't use them to source particular points. I just listed them as External references. --208.54.95.163 15:15, 10 October 2007 (UTC)Reply

The recent edit by JonMcLoone on the personal grid version says "Only four worker processes are provided". Yet the specifications on the Wolfram web site says "Each Mathematica Personal Grid Edition unit comes with five Mathematica kernel processes, one Mathematica front-end process, and one Parallel Computing Toolkit." Jon should know, so there is either a mistake somewhere, or I am mis-understanding the concept. Drkirkby 12:27, 13 October 2007 (UTC)Reply

Poor writing on my part. One Kernel generally does not participate in the parallel task. While, with some careful programming it could be fully utilized, its principal role in most cases is to handle the scheduling and distribution of tasks. So the master kernel IS a fifth kernel, but I think it would be misleading to list it in the same way as the four worker kernels. Not sure the best way to describe that succinctly.

JonMcLoone 13:28, 13 October 2007 (UTC)Reply

I've attempted to sumarise that, but someone else might feel they can do better - is so do so. Does this work similarly in gridMathematca, with 9 kernel proccess, only 8 of which are intended to be workers? 213.78.42.15 06:30, 14 October 2007 (UTC)Reply

Almost the same for gridMathematica. 9 Kernels provided, 8 as workers and 1 as master. The only difference is that if you purchase additional units (eg have 2 gridMathematicas) then you would have 18 kernels, with UP TO 2 as masters. While you could have two users with 8 workers, or 1 user with 4 workers and 1 with 12 etc... you could combine them with one user and up to 17 workers (IE the spare master can be re-deployed as a worker if you have only 1 user. Put another way Limit[Max[workers],gridUnits->Infinity]==9 ). This isn't an issue for Personal Grid as it is not extensible.JonMcLoone 09:18, 16 October 2007 (UTC)Reply

I provided some additional info that, I think, addresses this. —Preceding unsigned comment added by JonMcLoone (talk • contribs) 12:29, 31 October 2008 (UTC)Reply

With the release of gridMathematica 7, the design has changed significantly, so I have done a big re-write of the page. While I think that I have got across the main points, I can't spend the time to make this polished, and so it needs some additional editing. Also, I should disclose that I have been significantly involved in the release of this product. JonMcLoone (talk) 14:02, 19 March 2009 (UTC)Reply
