I have the adjacency matrix of a graph. I'm trying to find all triangles (embeddings of C_3). This doesn't work: index = function(l) seq(l)[l] pairs = do.call(rbind, lapply(seq(nrow(adj)), function(x) cbind(x, index(adj[x,])))) triangles = do.call(rbind, apply(pairs, 1, function(x) cbind(x, index(adj[x[1],] & adj[x[2],])))) I'm absolutely certain I've gone down the wrong path

I was looking at "trunc" to downcast a signed integer, say sint32 to sint16, but it seems to handle unsigned integers only. How do you downcast a signed integer? P.S. This question is for my "Mapping High-Level Constructs to LLVM IR" document :-) -- Mikael -------------- next part -------------- An HTML attachment was scrubbed... URL:

One piece of code I'm writing has a lot of intermediates, and I'm trying to optimize down the number of memory accesses. Here's a snippet from the start of the function, where I think there is some low-hanging fruit: # BB#0: pushq %rbp pushq %r15 pushq %r14 pushq %r13 pushq %r12 pushq %rbx movq %rdx, %rcx movq %rdi, -16(%rsp) # 8-byte Spill movq (%rsi), %rdi movq

I'd like to convert a dist into a table/matrix/thingy of the form: A B value A C value B C value (assuming the dist was over 3 names). Is there a way to do this without using a for loop? -- Taral <taralx at gmail.com> "Please let me know if there's any further trouble I can give you." ? ? -- Unknown

I saw some mail go by a bit ago about doubles-vs-floats, but I seem to have lost it. I'm interested in rewriting the mdct code using Altivec on MacOS X. Altivec doesn't support doubles, though -- the only floating point vector type is single precision floats. Vorbis currently has doubles everywhere -- is this really necessary? Doubles are supposedly faster than floats in the PPC

Hello > I was looking at "trunc" to downcast a signed integer, say sint32 to sint16, > but it seems to handle unsigned integers only. No. In twos-complement notation (which LLVM assumes) there no difference between signed and unsigned truncation - you just throw out the spare sign bits and that's all. Please note that that the "numbers" in LLVM IR is neither signed

Hi, I don't really know the details of the discussion, but I'd like to present this issue from a user-oriented perspective, and from the perspective of how Nautilus wants to use data files. In brief, Nautilus makes the assumption that the mime type is sufficient to pick the right applicatiob or pluggable component to view/edit a particular content type. This is quickly coming to be the

An update, and a very interesting one! After I started stracing rsync, all I could see was lstat calls, quite slow ones, over and over, which is expected. For example: lstat("uploads/2016/10/nexus2cee_DSC05339_thumb-161x107.jpg", {st_mode=S_IFREG|0664, st_size=4043, ...}) = 0 I googled around and found https://gist.github.com/nh2/1836415489e2132cf85ed3832105fcc1, which is seeing this

Today, our network has been excruciatingly slow. I checked the log.nmb file, and I noticed that today, the Samba PDC has been losing its "local master browser" status every 2 minutes or so, for about 15 seconds, to a Win9x client. Before today, this also happened, but only a few times each day. Network configuration: 1. All clients are Win9x. 2. Server is SuSE 6.1, with Samba 2.0.5.

I’m taking a first look at InstCombine performance. I picked up the caching patch and ran a few experiments on one of our larger C++ apps. The size of the *.0.2.internalize.bc no-debug IR is ~ 30M. Here are my observations so far. Interestingly, caching produced a slight but measurable performance degradation of -O3 compile time. InstCombine takes about 35% of total execution time, of which ~20%

Running Mac OS 10.5.8 Wine version 1.2.3 I'm trying to play Civ II, and it plays, just everything moves excruciatingly slow - even for Civ. How can I speed it up?

Everyone might be interested in knowing that videolan's cvs tree, combined with the excruciatingly simple patch attatched, is capable of playing back chained ogg/theora+vorbis streams. (encoded with example cvs). For example, icecast video. videolan has decided to parse vorbis, speex, theora headers with its own code. There's an ogg demuxer (the file I patched) and the codecs are each

Hi all, Is it a necessity to use the winbind nss module? I have run a few tests and having it enabled creates a massive bottleneck. It's not nss_winbind itself that is the bottleneck but something in the background (I'm guessing uid/rid->username code). If I disable winbind in nsswitch.conf what impact will it have? Will the system continue to work? eg: #nss_winbind enabled on

I have to say... since it''s bugged me _many_ times, that i *hate* these text boxes with the sliders that are being used to display text (for instance, on Rails documentation pages... but it''s not just Rails). Very often you can''t really read the text because it goes past the right border of the box. So you have to go to the bottom of the box to move the slider to
