Course Announcement
Dear everyone, Your code is slow and you are interested in performance optimization for scientific software? Figuring out where’s the bottlenecks guided by performance evaluation tools. If you are interested in porting your code to a HPC hardware platform and architecture, than OpenACC as a user-driven directive-based performance-portable parallel programming model might be a solution.

labRow/labCol options in heatmap()
The function heatmap() allows to specify row/column labels via the options labRow/labCol. From the code of heatmap(), I understand that when no labels are specified, the row/column labels (or indices) of the input matrix are taken as labels and re-ordered together with the rows and columns of the matrix before plotting, whereas labels supplied via labRow/labCol are plotted in the original order.

pheno package
Dear R-people, I tried to use a command seqMK(x) of the pheno package. However, the installation of the package fails with following error message: Error in library(pkg, character.only = TRUE) : 'pheno' is not a valid package -- installed < 2.0.0? What is the matter? Can anybody help me? I installed the latest version of R. Cheers, Anja --

[LLVMdev] Git repository to use (read-only)?
Hi, we want to use LLVM together with clang internally for preprocessing and Co. Therefor we would like to integrate it in our buildsystem. The nicest thing for us would be a local git repository mirror, to allow us to easily create own branches and Co. Is there some official git repository to clone from? I looked up the archives and seen that creating own clones of the SVN via git svn is not

Question about llvm::Value::print performance
Hi, I want to use llvm::Value::print to output the assembly strings for llvm::Instructions inside a rather large llvm::Module (linked module with lots of types/...). I started with plain ::print and switched over to http://llvm.org/docs/doxygen/html/classllvm_1_1Value.html#a04e6fc765eeb0c4c90ac5d55113db116 with a ModuleSlotTracker I pass in myself to avoid some complexity. Still now I have

RE: [ofa-general] Infiniband performance
Hi Jan, I asked almost the exact same question as you about 6 months ago and someone provided some Gen4 results for me (But I can''t seem to find them in email), they were a fair bit better than Gen3. With IPOIB, you want connected mode and a large 32Kb+ MTU for max bandwidth, 1Gbyte/sec or more should be possible with Gen 4. Here are some of my original test results on my Opteron

[LLVMdev] Git repository to use (read-only)?
It's not *very* easy to do, but if you were to pull in the new branch, and then rebase the old branches onto the proper revisions of the new one, you *could* keep your branches. Also, any idea what is *very* soon? Are we talking this month, or maybe this year?

[LLVMdev] Question about non-UTF-8 filesystems
Hi, it seems that e.g. on Windows, where the filename encoding is not UTF-8, it is impossible to use any filenames containing e.g. german umlauts or chinese characters, because the in LLVM used encoding collides with the encoding used by the OS. There is a open bug for this http://llvm.org/bugs/show_bug.cgi?id=10348 It seems there were patches submitted to fix it, but they were never applied as

Correct modelling of instructions with types smaller than the register class
Hi Quentin, thank you for the reply! This clears up a lot of the questions I was having. It seems like we should definitely invest some time in rewriting some of our legalization rules then! I also posted some questions further down below. I would appreciate getting your opinion on them. > Hi Dominik, > > I’ll do a brief reply here and if you want more information we can talk further

Exceptions not getting caught on bare-metal target
Hi, We're working on adding exception handling support for a downstream bare-metal target. I read through the LLVM exception handling docs [1] and went through some patches from other backends to understand what parts we need to implement. We're now at a point were it feels like it should work, but unfortunately exceptions are still not getting caught. Our target uses DWARF

I've surfed through the R- an Omegahat-Pages, because I'd like to use RGTK2, GTK 2.10.11 in combination with glade on Windows XP (perhaps later Unix, Mac). I've found a lot of different information. Because of the information I'm not sure, if this combination is running on Windows XP and I'm unsure how it works. Is

Supporting freeze in GlobalISel / freeze semantics in MIR
Hi all, After a recent upstream merge into our downstream sources we are suddenly encountering the freeze instruction in LLVM IR for div/rem pairs. This seems to be related to [1]. Our downstream target is GlobalISel only and unfortunately GlobalISel doesn't support this instruction yet, so most of our internal test-suite is now breaking due to GlobalISel not being able to translate this

WISP-survey part of created area?
Dear R-Team! I am a beginner in R and use the WISP library for a project. I am using mark-recapture to estimate abundance. I would like to know if it is possible to only survey a part of the created area (with the created population) and not all of it. I am trying to quantify bias introduced by non random sampling design (i.e. the area is 24x100 but I only wanna search 24x40) Thank you already in
