Hey All, Curious about the best, easy to use virtualization management platform for small labs of 30-40 physical servers. Looking for something that's relatively simple to operate, install and lightweight but with enough maturity to provide monitoring as well as holistic views of the entire physical space etc. Hearing of oVirt, Xen and Eucalyptus to name a few but wondering what other options do I have for a small physical space? -- Cheers, Tom K.

...nce it's constrained to be the same as the 64-bit "input register". That means that you ought to make sure to set *both* output registers appropriately, one of them being 0 and the other being the 32-bit number. I think that's the only answer that actually makes any sense from a holistic code-generation sense. So it seems we are in violent agreement :-D. Cheers, Kyle Moffett

Hello, I run into a situation where I need to provide the library functions, such as sqrt() from <math.h> and rand() from <stdlib.h>, in the format of LLVM IR bitcode files. Then I can try to link the bitcode of my program against these library bitcode files to formulate a holistic bitcode file. However, these library functions are only available in object format. And the source files of them I found have many references to other library files. So, is there any way to translate the library source files into bitcode files, so that all the information that the library functio...

But it sounds like a redesign is planned for some time in the future. -Jochen

I had intended to come back to this but because I didn't really think I had anything to add to the discussion I put it at a low enough priority that I forgot about it. But I saw your bug report and was surprised to see that I was already unhelpful on this topic but because that original poster didn't have access to do an rm while you are trying to get a performance boost. I have

I don't think it's worth considering the two projects separately, we should lump and count.

...hich is part of the statistical analysis. And the structure of the data (data preparation) may need to change depending on the course of the analysis (including graphics, also part of the analysis). So I think your view reflects a na?ve view of the nature of data analysis, which is an iterative and holistic process. I suspect your training is as a computer scientist and you have not done much 1-1 consulting with researchers, though you should certainly feel free to reject this canard. Building software for large scale automated analysis of data required a much different analytical paradigm than the st...

This level is all about compile time, but in a holistic sense. It tries to perform basic optimizations to get reasonably efficient code, and get it very quickly. 4) Good, well-balanced optimizations, or '-O2' - Attribute: opt (new attribute) - Goal: produce a well optimized binary trading off compile time, space, and runtime efficiency.
