Dear Srs, In the page: http://wiki.centos.org/HowTos/Virtualization/OpenVZ Section -> "Additional Resources" "Performance evaluation of Xen vs. OpenVZ by HP Labs" link is broken, it points to: http://www.hpl.hp.com/techreports/2007/HPL-2007-59.pdf And the PDF has been moved to: http://www.hpl.hp.com/techreports/2007/HPL-2007-59R1.pdf Regards, -- Santi Saez http://woop.es

C++ and Java memory models impose restrictions for locks and unlocks, such as a thread that releases a lock must acquired the lock, or the number of locks must be larger than the number of unlocks in the same thread... for enabling some optimizations, for example, simplifying trylocks (http://www.hpl.hp.com/techreports/2008/HPL-2008-56.html), and moving some instructions inside lock acquires (http://www.hpl.hp.com/techreports/2005/HPL-2005-217R1.html). What is the rationale that the LLVM memory model ignores such restrictions? On Mon, Jul 18, 2011 at 8:22 PM, Eli Friedman <eli.friedman at...

...rge enough. In our case we run find . -print0 -type f | xargs -0 cat > /dev/null on the client until the buffer cache reaches ~15-20GB. (The lustre file system has lots of small files so this takes up to an hour.) Kill the find process and start a single node parallel application, we use HPL (high performance linpack). We run on all 16 cores on the system with 1GB ram per core (a normal run should complete in appr. 150 seconds.) The system monitoring shows a 10-20% system cpu overhead and the HPL run takes more than 200 secs. After running "echo 3 > /proc/sys/vm/drop_cac...

There was some discussion a while back about adding a C++0x-style memory model and atomics for LLVM a while back (http://thread.gmane.org/gmane.comp.compilers.llvm.devel/31295), but it got stalled. I'm going to try and restart progress on it. Attached are two patches; the first adds a section to LangRef with just the memory model, without directly changing the documentation or implementation

Some of you may have noticed that I addedd include/llvm/System/ Atomics.h to the repository briefly, which will be used for adding support for threading in LLVM. I have tried to provided appropriate implementations of the atomic ops (currently memory fence and CAS) for platforms we care about, but my knowledge of these, and my ability to test them, is limited. So, please, if you run on

If you're interested in the evolution of C++'s memory model, here are some papers on the topic: http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2008/n2664.htm http://open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2429.htm http://open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2427.html A working draft for the next C++ standard is also available:

I haven't noticed any work on Trusted HP-UX 10.26 in the archives (then again maybe I missed it). I have made changes to get sshd working on trusted HP-UX, ssh already worked. I can supply a patch, but before I did I was wondering if it is best to send the patch to this list, or file it as a bug report? The patch is just around 6k, and includes changes to configure.ac and acconfig.h, allong

Hi, I'm involved in a bioinformatics project at my university, and we're doing a comparison paper between some methods of classification of nc-RNA. I've been encharged of ploting the ROC curves' graphs. But I'm new on working with R and I'm having some difficulty with the prediction-class. I don't get where the values of ROCR.simple$predictions, for example, came from

...re the reboot. The worst I have seen are a couple of "Timer went backwards" error messages but they don''t always show up in the logs. Anything else I should be poking at to figure out why this might be happening and if there are any potential fixes?
