...; Could you please help me? I suspect this is highly code-dependent. For example, it's probably feasible to use static analysis to determine error paths, at least for fairly well-behaved programs. A whole-program analysis might be able to better determine such paths but that's likely too heavyweight for a JIT. AOT could do it and use metadata to guide the JIT. On some codes, paths within a loop may be fairly evenly distributed over iterations while for others, execution may be highly biased toward a few. This is probably going to be the most difficult thing to analyze statically without a lo...

In general, I/O in a virtual guest is subject to performance problems. = The I/O can not be completed physically, but must be virtualized.

Just wondering what people tend to use for nullmailers on their centos boxes (i.e. a minimal outgoing-only MTA)? I guess the obvious solution is a minimal postfix config, but that seems reasonably heavyweight and easy to misconfigure - is there anything lighter floating around the centos universe?

Hi, as per the shorewall MultiISP documentation ( http://www1.shorewall.net/MultiISP.html ), it says "Use of this feature requires that your kernel and iptables include CONNMARK target and connmark match support (Warning: Standard Debian™ and Ubuntu™ kernels are lacking that support!)." it means MultiISP wont work properly if i am using Ubuntu server. if yes whats the

Hello All, There seems to have been a lot of interest in getting wxScintilla incorperated, and I think most of us who want it, want it so we can create an editor, so to avoid multiple projects comming out with the same goal (Not really that bad of a problem....), I''m going to kick start this, and ask that anyone interested in developing a Editor with wxRuby and wxScintilla, to send

...but here are some numbers on OS X for comparison: > > 5,282,356 libLLVMCodeGen.a Comparing the size of the static libraries makes little sense, and even less when they are compiled by different tools. What really matters is the size of the executables. I agree that LLVM can be considered a heavyweight dependency on this aspect. [snip]

I'm given to understand that the recommendation these days is to use libOption instead of cl::opt, on the grounds that it has a number of advantages including more control of which options are made available. Is there any information available on how to use libOption, any documentation or example programs? Do any existing programs use it except the clang driver programs? Those customise their

...e Omega a lot and it is a fine choice for the first solver. Although it is very powerful, even it cannot handle symbolic loop strides. Perhaps more importantly for common uses, for many trivial cases (A[x] and A[x+1]), setting up the Omega data structures to invoke the solver can be too heavyweight. It could be worthwhile to add one or more simple solvers (see the Allen and Kennedy textbook for examples) before falling back on Omega. > > > Sebastian > _______________________________________________ > LLVM Developers mailing list > LLVMdev at cs.uiuc.edu http://...

...nt in llvm.org only talk about pretty heavy weight integration tests (Tcl + FileCheck, .cpp -> (many compilers ...) which is fine, but, but as a sanity check, I can't seem to find an example of a test.cpp file that invokes a certain subset of LLVM API, and self-checks the result - Or is the heavyweight "compile a .cpp file and cross check LLVM-clang's output to gcc" the only way something like this supported? Thanks, -Jason. -jason

...rver shuts down unexpectedly, this isn't done, and the hardware clock might be off by a lot when it comes back up. So setting it periodically from a cron job could be useful. What do others do? Adding a one liner to /etc/cron.daily that invokes /etc/rc.d/init.d/ntpd would do it but it seems heavyweight to restart ntpd. Alas, the script doesn't export just the sync_hwclock function.

hi I try to understand the code of xen memory there are gmfn, gpfn and pfn in the xen and in the /xen/include/xen/mm.h there are some explanation about them as follows: * 1. gpfn/gpaddr: A guest-specific pseudo-physical frame number or address. * 2. gmfn/gmaddr: A machine address from the p.o.v. of a particular guest. * 3. mfn/maddr: A real machine frame number or address. * 4.

...th elements. Problems: feels like reinventing HDF, cross-platform issues, etc. * Store the data in a number of .RData files in a directory. Hence to get the N-th element just attach(paste("foo/A-",n,'.RData')) give or take a parameter or two. * Use a database. Seems a bit heavyweight, but maybe using RSQLite could work in order to keep it local. What I'm currently doing is keeping it OO enough that I can in theory implement all of the above. At the moment I have an implementation that does keep them all in R's memory as a list of data frames, which is fine for sm...

...ll be available to views, I write a helper function in one of the places set aside or that very task by Rails. If I want to write a little suite of functions to be mixed in by a number of model classes (but not all), where do I put them? Plug-ins look like AN answer, but they also seem a little heavyweight for simple, project-specific tasks.

...nOffice installed, so I'm not interested in the updates for OpenOffice 1.1.2-24.6.0.EL4 which are now coming in. Is there a way to instruct yum to ignore this update but accept other updates? Sorry if this is a dumb question, but in spite of many years working with Linux I'm not an rpm/yum heavyweight. I'm sure, however, others may appreciate the answer.

...apply only to a graphical menu, as I didn't see any effect with a text menu. The Wiki should clearly state what they apply to. 3. Is there a tool that would let me see the PXE boot menu at my desk, instead of having to go physically boot a machine to see it? Using a VM is too heavyweight. I would expect something in the syslinux suite or a 3rd party tool that could at least show the menu.c32 text menu at a [SSH] console or a graphical desktop.

...esitate to show up, would be so much appreciated!!! The NHW codec has a high speed, which makes it a good candidate for mobile, embedded devices.There are currently some exploration for a MotionJPEG replacement on low power processor (dual-core 240MHz Xtensa LX6) where MotionJPEG appears to be too heavyweight. With the recent updates, I think the NHW Project is still patent-free and royalty-free. And just the fact that it is royalty-free, should be worth the try. So with this new version, I hope the NHW Project could attract a company that would like to sponsorize the project (to adapt the codec to an...
