...s the easiest way to program SIMD units is to use a single-program, multiple-data (SPMD) model, with each instance of the program mapped to one SIMD lane. We discuss language features that make ispc easy to adopt and use productively with existing software systems and show that ispc delivers up to 35x speedups on a 4-core system and up to 240x speedups on a 40-core system for complex workloads (compared to serial C++ code). -------------- next part -------------- An HTML attachment was scrubbed...

...gt; Any thoughts? From <http://www.rockbox.org/wiki/CodecPerformanceComparison> it seems that the decoding of -8 is about 6% slower than -5. Sometimes the difference is bigger but doesn't exceed 10%. The only exception is "Freescale i.MX21 (454MHz ARM926EJ?-S, Fuze+)": 43x vs 35x realtime. But the decoding time is so small (4 sec vs 5 sec) that it can be some measurement error.

...ted dependency on http://wiki2.dovecot.org/Plugins/FTS/Lucene, but not part of the FreeBSD makefile: maybe that helped, maybe it was irrelevant). However, I now get some anomalous results. I'm putting them together as they may be related. Or, maybe not. 1) Searching from Thunderbird returns 35x as many results for the same term as searching from the command line. I'm not sure if the indexes are created or enumerable. 2) There seems to be a glitch in the maildir naming structure that results in a double slash (//) which doesn't seem to impact IMAP serving or Sieve, but maybe is...

...became popular recently. Unfortunately it does not prove to be good. I suggest you check the related work in QEMU. DBT part of both QEMU and Valgrind works in similar way. And there were a bunch of works on using LLVM as a QEMU backend. They resulted in slowdown mostly. In [1] the authors reported 35x slowdown, in [2] there were around 2x slowdown. Finally in [3] the authors reported performance gain, but there are some catches. 1. They used LLVM not only for backend. They replaced internal representation with LLVM. This is not an option for Valgrind because you'll need to rewrite all exist...

Welcome, I''ve been using btrfs for over a 3 months to store my personal data on my NAS server. Almost all interactions with files on the server are done using unison synchronizer. After another use of bedup (https://github.com/g2p/bedup) on my btrfs volume I experienced huge perfomance loss with synchronization. It now takes over 3 hours what have taken only 15 minutes! File

Along the same lines as the last question - how can I get to functions like MakeOpenFile via Win32API? It doesn''t seem to be exported by msvcrt-ruby18. Possible? Or am I out of luck?

Hi, Is the http://xenbits.xensource.com/linux-2.6-xen.hg tree still being updated? if not, what''s the preferred Linux tree to track that has all of the Xen bits?
