BUILD.NOTES

This information is meant primarily for the Slurm developers. 
System administrators should read the instructions at
http://www.llnl.gov/linux/slurm/quickstart_admin.html
(also found in the file doc/html/quickstart_admin.shtml).
The "INSTALL" file contains generic Linux build instructions.

Simple build/install on Linux:
  ./configure --enable-debug \
              --prefix=<install-dir> --sysconfdir=<config-dir>
  make
  make install

To build the files in the contribs directory:
  make contrib
  make install-contrib
  (The RPMs are built by default)

If you make changes to any auxdir/* or Makefile.am file, then run
_snowflake_ (where there are recent versions of autoconf, automake 
and libtool installed):
 ./autogen.sh
then check-in the new Makefile.am and Makefile.in files

Here is a step-by-step HOWTO for creating a new release of SLURM on a
Linux cluster (See BlueGene and AIX specific notes below for some differences).
0. svn co https://eris.llnl.gov/svn/slurm/trunk slurm
   svn co https://eris.llnl.gov/svn/chaos/private/buildfarm/trunk buildfarm
   put the buildfarm directory in your search path
1. Update NEWS and META files for the new release. In the META file,
   the API, Major, Minor, Micro, Version, and Release fields must all
   by up-to-date. **** DON'T UPDATE META UNTIL RIGHT BEFORE THE TAG ****
   The Release field should always be 1 unless one of
   the following is true
   - Changes were made to the spec file, documentation, or example
     files, but not to code.
   - this is a prerelease (Release = 0.preX)
2. Tag the repository with the appropriate name for the new version.
   svn copy https://eris.llnl.gov/svn/slurm/trunk \
     https://eris.llnl.gov/svn/slurm/tags/slurm-1-2-0-0-pre3 \
     -m "description"
3. Use the rpm make target to create the new RPMs. This requires a .rpmmacros 
   (.rpmrc for newer versions of rpmbuild) file containing:
	%_slurm_sysconfdir      /etc/slurm
	%_with_debug            1
	%_with_sgijob		1
	%_with_elan		1   (ONLY ON SYSTEMS WITH ELAN SWITCH)
   I usually build with using the following syntax:
   build  -s https://eris.llnl.gov/svn/slurm/tags/slurm-1-2-0-0-pre3
4. Remove the RPMs that we don't want:
   rm -f slurm-perlapi*rpm slurm-torque*rpm
5. Move the RPMs to
   /usr/local/admin/rpms/llnl/RPMS-RHEL4/x86_64 (odevi, or gauss)
   /usr/local/admin/rpms/llnl/RPMS-RHEL4/i386/ (adevi)
   /usr/local/admin/rpms/llnl/RPMS-RHEL4/ia64/ (tdevi)
   send an announcement email (with the latest entry from the NEWS
   file) out to linux-admin@lists.llnl.gov.
6. Copy tagged bzip file (e.g. slurm-0.6.0-0.pre3.bz2) to FTP server
   for external SLURM users.
7. Copy bzip file and rpms (including src.rpm) to sourceforge.net:
   ncftp upload.sf.net
   cd upload
   put filename
   Use SourceForge admin tool to add new release, including changelog.

BlueGene build notes:
3. Use the rpm make target to create the new RPMs. This requires a .rpmmacros
   (.rpmrc for newer versions of rpmbuild) file containing:
	%_slurm_sysconfdir      /etc/slurm
	%_with_debug            1
	%_with_bluegene         1
	%with_cflags		CFLAGS=-m64
   Build on Service Node with using the following syntax
   rpmbuild -ta slurm-...bz2

To build and run on AIX:
0. svn co https://eris.llnl.gov/svn/slurm/trunk slurm
   svn co https://eris.llnl.gov/svn/buildfarm/trunk buildfarm
   Put the buildfarm directory in your search path
   Also, you will need several commands to appear FIRST in your PATH:

      /usr/local/tools/gnu/aix_5_64_fed/bin/install
      /usr/local/gnu/bin/tar
      /usr/bin/gcc

   I do this by making symlinks to those commands in the buildfarm directory,
   then making the buildfarm directory the first one in my PATH.
   Also, make certain that the "proctrack" rpm is installed.
1. export OBJECT_MODE=32
2. Build with:
   ./configure --enable-debug --prefix=/opt/freeware \
	--sysconfdir=/opt/freeware/etc/slurm
	--with-ssl=/opt/freeware --with-munge=/opt/freeware
   make
   make uninstall  # remove old shared libraries, aix caches them
   make install
3. To build RPMs (NOTE: GNU tools early in PATH as described above in #0):
   Create a file specifying system specific files:
	#
	# RPM Macros for use with SLURM on AIX
	# The system-wide macros for RPM are in /usr/lib/rpm/macros
	# and this overrides a few of them
	#
	%_prefix                /opt/freeware
	%_slurm_sysconfdir      %{_prefix}/etc/slurm
        #%_defaultdocdir         %{_prefix}/doc
	%_with_debug            1
	%_with_aix		1
	%with_ssl               "--with-ssl=/opt/freeware"
	%with_munge             "--with-munge=/opt/freeware"
	%with_proctrack         "--with-proctrack=/admin/llnl/include"
   Log in to the machine "uP".  uP is currently the lowest-common-denominator
     AIX machine.
   CC=/usr/bin/gcc build -s https://eris.llnl.gov/svn/slurm/tags/slurm-1-2-0-0-pre3
4. export MP_RMLIB=./slurm_ll_api.so
   export CHECKPOINT=yes
5. poe hostname -rmpool debug
6. To debug, set SLURM_LL_API_DEBUG=3 before running poe - will create a file
     /tmp/slurm.*
   It can also be helpful to use poe options "-ilevel 6 -pmdlog yes"
   There will be a log file create named /tmp/mplog.<jobid>.<taskid>
7. If you update proctrack, be sure to run "slibclean" to clear cached
   version.
8. Remove the RPMs that we don't want:
   rm -f slurm-perlapi*rpm slurm-torque*rpm
   and install the other RPMs into /usr/admin/inst.images/slurm/aix5.3 on an 
   OCF AIX machine (pdev is a good choice).

AIX/Federation switch window problems
To clean switch windows:     ntblclean =w 8 -a sni0
To get switch window status: ntblstatus

BlueGene bglblock boot problem diagnosis
  - Logon to the Service Node (bglsn, ubglsn)
  - Execute /admin/bglscripts/fatalras
    This will produce a list of failures including Rack and Midplane number
    <date> R<rack> M<midplane> <failure details>
  - Translate the Rack and Midplane to SLURM node id: smap -R r<rack><midplane>
  - Drain only the bad SLURM node, return others to service using scontrol

Configuration file update procedures:
  - cd /usr/bgl/dist/slurm (on bgli)
  - co -l <filename>
  - vi <filename>
  - ci -u <filename>
  - make install
  - then run "dist_local slurm" on SN and FENs to update /etc/slurm

Some RPM commands:
  rpm -qa | grep slurm                  (determine what is installed)
  rpm -qpl slurm-1.1.9-1.rpm            (check contents of an rpm)
  rpm -e slurm-1.1.8-1                  (erase an rpm
  rpm -i --ignoresize slurm-1.1.9-1.rpm (install a new rpm)
For main SLURM plugin installation on BGL service node:
  rpm -i --force --nodeps --ignoresize slurm-1.1.9-1.rpm


To clear a wedged job:
  /bgl/startMMCSconsole
  > delete bgljob ####
  > free RMP###

Starting and stopping daemons on Linux:
  /etc/init.d/slurm stop
  /etc/init.d/slurm start

Patches:
  - cd to the top level src directory
  - Run the patch command with epilog_complete.patch as stdin:
    patch -p[path_level_to_filter] [--dry-run] < epilog_complete.patch

To get the process and job IDs with proctrack/sgi_job:
  - jstat -p

CVS and gnats:
Include "gnats:<id> e.g. "(gnats:123)" as part of cvs commit to
automatically record that update in gnats database. NOTE: Does
not change gnats bug state, but records source files associated
with the bug.

For memory leaks (for AIX use zerofault, zf; for linux use valgrind)
 valgrind --tool=memcheck --leak-check=yes --num-callers=6 --leak-resolution=med ./slurmctld

Before new major release:
 - Test on ia64, i386, x86_64, BGL, AIX, OSX, XCPU
 - Test on Elan and IB switches
 - Test fail-over of slurmctld
 - Test for memory leaks in slurmctld and slurmd
 - Change API version number
 - Review and release web pages
 - Review and release code
 - Run "make check"
 - Test that the prolog and epilog run
 - Run the test suite with SlurmUser NOT being self
