The project can be found at: http://sourceforge.net/projects/linuxsuperpages The major benefit of supporting Superpages is increased memory reach of the processor's TLB, which reduces the number of TLB misses in applications that have large data sets. Some benchmarks have been improved 20% in execution time. Reference www.cs.rice.edu/~jnavarro/superpages/ for more information about the Rice University's Superpages project. The project is being made available to the Open Source community to share the implementation and knowledge. With the enhancements to the x86 architectures to support multiple and large page sizes there should be increased interest in this functionality. /Tom Tom Wildman Hewlett-Packard Company 200 Forest Street Phone: 978.841.7648 Marlboro, MA 01752 Email: tom.wildman@hp.com -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
