Remember that votes above 10 do not help a proposal to complete its definition phase, so many people consider every vote over 10 to be a wasted vote. It is far more useful to use your votes to approve of questions with fewer than 10 votes. Also, if a question you have already voted on now has more than 10 votes, remember that you can remove your up vote at any time and put it on another suitable question. – Mark Booth Apr 12 at 16:30

How do you virtualize a GPU? How do companies offer GPU's based cloud solutions?
added by Saariko Oct 4 '12 at 5:41

The second question is shopping, which is off-topic on all SE sites. – Chris S Feb 22 at 21:44
@Chris How is "how do companies offer such solutions?" a shopping question? – mattdm Feb 22 at 21:59
It might worth 2 questions indeed, but shopping? That's not the intention of the question. Had I asked: Which company offer .... - alas... The idea is to understand how do companies, and with which/what technology they use to offer such GPU virtualization – Saariko Feb 23 at 16:53

How about "How can I tune performance in VMWare on a Mac with a dual-core processor, 4GB of RAM, and OS X 10.7 without using up too much resources on the host?". This would be less broad and more specific and answerable. – jmort253 Oct 4 '12 at 5:53
