Build Instructions for XDD release -- Supported OS: Linux, AIX, OSX On supported OS: > ./configure > make > make install By default, XDD and supporting scripts are installed in /usr/bin and /usr/lib, in order to change the installation path, use --prefix=<new path> during the configure step. By default, the following features are enabled: XFS support, NUMA support, and Infiniband support. If you do not need these features, or cannot install the relevant support libraries, you can disable each of these features individually during configure with the following flags, respectively: --disable-xfs, --disable-numa, and --disable-ib. Build instructions for XDD repository code -- If you are using the git repository version of XDD (i.e. you are a prospective XDD developer), you will need to add one more step during the software build process. We also suggest enabling debug mode. On supported OS: > autoconf > ./configure --enable-debug > make > make install XFS pre-allocation support -- File preallocation on end-to-end transfers currently only works for the XFS file system. This is mainly because the posix_fallocate call is supported inconsistently in Linux, and so we are making the direct fctl call in the case of XFS file systems. We attempt to enable preallocate on XFS if we can find the correct headers in the default places. But if the headers are not easily locatable then we do not enable XFS preallocation support. The configure script controls xfs preallocation with with an explicit enable/disable flag. To guarantee that XFS preallocation is enable, use the following: > ./configure --enable-xfs To disable XFS preallocation, use the following instead: > ./configure --disable-xfs The defaults have been tested on Fedora 12, Scientific Linux, and Suse only. Qdepth/Thread count advisory -- In XDD, the number of threads is often governed by the queue depth option or the thread count option. The number of threads than may be created is system dependent. For example, on my laptop I can only create 916 threads before the system returns a "resource busy or unavailable" error. Its not just a simple memory limitation necessarily either (i.e. reducing the pthread stack size doesn't automatically increase the number of threads you can create). In general, the number of threads that can be initialized by XDD is limited by the system rather than XDD. This is mainly interesting when using fork-thread type access patterns.
