Contains the following sections: - INTRODUCTION - DEPENDENCIES - BUILDING - BUILDING USING MAKEFILE - BUILDING USING RPMBUILD (CREATING SOURCE AND BINARY RPM'S) - INSTALLING USING MAKEFILE - INSTALLING USING RPM - RELATED SOFTWARE TO PSM INTRODUCTION ------------ This README file discusses how to build, install and test the PSM 2 library source code. The PSM 2 library supports a number of fabric media and stacks, and all of them run on version 7.X of Red Hat Enterprise Linux (abbreviated: RHEL), and SuSE SLES. Only the x86_64 architecture is supported. As of this writing, (July 21, 2015) OPA is not natively supported in any RHEL 7.X kernel, and building PSM on a host w/o native OPA is not possible unless you have the correct kernel-devel package; but if you have a modern version of the IFS (Infiniband Fabric Suite), you should be able to build it. It is easier if you wait until the hfi1 driver is upstreamed and becomes part of the RHEL 7.X. There are two mechanisms for building and installing the PSM 2 library: 1. Use provided Makefiles to build and install or 2. Generate a tarball that can be used to build source and binary RPMs using rpmbuild DEPENDENCIES ------------ The following packages are required to build the PSM 2 library source code, all packages are for the x86_64 architecture: compat-rdma-devel gcc-4.8.2 glibc-devel glibc-headers kernel-headers libuuid-devel In addition to depending on these packages, root privileges are required to install the runtime libraries and development header files into standard system location. BUILDING -------- The instructions below use $PRODUCT and $RELEASE to refer to the product and release identifiers of the opa-psm RPM. BUILDING USING MAKEFILES ------------------------ 1. Untar the tarball: $ tar zxvf opa-psm-$PRODUCT-$RELEASE.tar.gz 2. Change directory into the untarred location: $ cd opa-psm-$PRODUCT-$RELEASE 3. Run make on the command line. This will build the PSM 2 library. $ make BUILDING USING RPMBUILD ----------------------- This is a two step process: Generate a PSM distribution tarball which can then be used to generate source and binary RPMs using the rpmbuild command with the -ta option. 1. Untar the tarball: $ tar zxvf opa-psm-$PRODUCT-$RELEASE.tar.gz 2. Change directory into the untarred location: $ cd opa-psm-$PRODUCT-$RELEASE 3. Generate distribution tarball $ make dist 4. Generate source and binary packages $ rpmbuild -ta hfi1-psm-$PRODUCT-$RELEASE.tar.gz As of this writing (July 21, 2015), this command results in the following collection of rpm's and source code rpm's to populate your rpmbuild directory tree in your home directory: RPMS/x86_64/hfi1-psm-0.7-95.x86_64.rpm RPMS/x86_64/hfi1-psm-devel-0.7-95.x86_64.rpm RPMS/x86_64/hfi1-psm-compat-0.7-95.x86_64.rpm RPMS/x86_64/hfi1-psm-compat-devel-0.7-95.x86_64.rpm RPMS/x86_64/hfi1-psm-debuginfo-0.7-95.x86_64.rpm SRPMS/hfi1-psm-0.7-95.src.rpm INSTALLING USING MAKEFILE ------------------------- Install the libraries and header files on the system (as root): $ make install The libraries will be installed in /usr/lib64, and the header files will be installed in /usr/include. This behavior can be altered by using the "DESTDIR" and "LIBDIR" variables on the "make install" command line. "DESTDIR" will add a leading path component to the overall install path and "LIBDIR" will change the path where libraries will be installed. For example, "make DESTDIR=/tmp/psm-install install" will install all files (libraries and headers) into "/tmp/psm-install/usr/...", "make DESTDIR=/tmp/psm-install LIBDIR=/libraries install" will install the libraries in "/tmp/psm-install/libraries" and the headers in "/tmp/psm-install/usr/include", and "make LIBDIR=/tmp/libs install" will install the libraries in "/tmp/libs" and the headers in "/usr/include". INSTALLING USING RPM -------------------- You can install the rpm's and source rpm's previously built using rpmbuild using the rpm command, as the root user. See the rpm man page for details of installing rpm's. RELATED SOFTWARE TO PSM ======================= MPI Libraries supported ----------------------- A large number of open source (OpenMPI, MVAPICH, MVAPICH2) and Vendor MPI implementations support PSM for optimized communication on HCAs. Vendor MPI implementations (HP-MPI, Intel MPI 4.0 with PMI, Platform/Scali MPI) require that the PSM runtime libraries be installed and available on each node. Usually a configuration file or a command line switch to mpirun needs to be specified to utilize the PSM transport. OpenMPI support --------------- It is recommended to use the OpenMPI v1.5 development branch. Prior versions of OpenMPI have an issue with support PSM network transports mixed with standard Verbs transport (BTL openib). This prevents an OpenMPI installation with network modules available for PSM and Verbs to work correctly on nodes with no HFI hardware. This has been fixed in the latest development branch allowing a single OpenMPI installation to target HFI hardware via PSM or Verbs as well as alternate transports seamlessly. PSM header and runtime files need to be installed on a node where the OpenMPI build is performed. All compute nodes additionally should have the PSM runtime libraries available on them. OpenMPI provides a standard configure, make and make install mechanism which will detect and build the relevant PSM network modules for OpenMPI once the header and runtime files are detected. MVAPICH and MVAPICH2 support ---------------------------- Both MVAPICH and MVAPICH2 support PSM transport for optimized communication on HFI hardware. MVAPICH2 1.4 and MVAPICH 1.2 versions are recommended. PSM header and runtime files need to be installed on a node where MVAPICH builds are performed. All compute nodes additionally should have the PSM runtime libraries available on them. MVAPICH provides a shell script in its top level directory called make.mvapich.psm to configure, make and install MVAPICH with PSM support. MVAPICH2 provides a standard configure and make infrastructure. In order to MVAPICH2 for PSM the following should be performed from the top level directory: - ./configure --prefix=<path_to_install_mvapich2> --with-device=ch3:psm - make - make install OFED Support ------------ OFED 1.5.1rc2 or above should be installed on the node. Prior versions of OFED have an older HFI driver (ib_qib) and do not fully support all the PSM features with this release.
