2
Stable vs. Development Series
  • Much like the Linux kernel, Condor provides two
    different releases at any time
  • Stable series
  • Development series
  • Allows Condor to be both a research project and a
    production-ready system

3
Stable series
  • Series number in version is even (e.g. 6.2.0)
  • Releases are heavily tested
  • Only bug fixes and ports to new platforms are
    added on a stable series

4
Stable series (cont.)
  • A given stable release is always compatible with
    other releases from the same series
  • Recommended for production pools

5
Development Series
  • Series number in the version is odd (e.g. 6.1.17,
    6.3.0)
  • New features and new technology are added
    frequently
  • Versions from the same development series are not
    always compatible with each other

6
Development Series (cont.)
  • Releases are not as heavily tested
  • Generally not recommended for production pools
  • unless new features are required
  • unless we recommend otherwise )

7
Where is Condor Today?
  • New stable version 6.2.0 recently released
  • Previous development series cycle, ver 6.1., was
    far too long
  • This was our first stable/development series
    we're hopefully learning...

8
New Ports in 6.2.0
  • Full support (with checkpointing and remote
    system calls)
  • All current versions of Linux (x86)
  • Kernel 2.2. and 2.0.
  • C Library glibc-2.01 and libc-5
  • NOTE libc5 support dropped
  • Solaris 2.7 and 2.8(Sparc and x86)
  • Irix 6.5

9
New Ports in 6.2.0 (cont.)
  • Clipped" support (no checkpointing or remote
    system calls, but all other functionality is
    available)
  • Windows NT
  • Alpha Linux

10
What is New in 6.2.0?
  • Personal Condor and Grid Support
  • Flocking
  • Proof-of-concept support for
  • Globus Job Universe
  • Globus Glide-In
  • Full, integrated support for Symmetric
    Multi-Processor (SMP) machines

11
What's New in 6.2.0? (cont.)
  • PVM support
  • DAGMan (for managing inter-job dependencies)
  • Use of machine ClassAd attributes in submit file
  • Example
  • Executable foo.(ARCH).(OPSYS)

12
What's New in 6.2.0? (cont.)
  • Greatly expanded I/O support for STANDARD
    universe jobs
  • Condor can automatically buffer I/O requests from
    jobs
  • Compression/decompression on-the-fly!
  • Users get much more information about the kinds
    of I/O their jobs are performing
  • Users can "remap" files to alternate locations

13
What's New in 6.2.0? (cont.)
  • CondorVersion and CondorPlatform strings included
    in all binaries and libraries
  • Helps identify and avoid problems with having the
    wrong version installed
  • Different parts of the Condor protocol
    automatically check for version incompatibilities

14
What's New in 6.2.0? (cont.)
  • Better accounting
  • Historical usage logging in collector
  • Use condor_stats
  • web interface called CondorView
  • Accountant stores usage information per user
  • Better control over user priorities
  • "Priority factors"

15
What's New in 6.2.0? (cont.)
  • More powerful administration tools
  • Setting configuration values remotely
  • Querying daemons directly for status
  • Other misc new tools
  • condor_findhost, condor_hold/release,
    condor_qedit, condor_userlog, condor_run,
  • Lots of performance and bug fixes
  • A complete list is online in the manual
    (www.cs.wisc.edu/condor/manual)

16
The 6.3 Development Series
  • Major focus areas for ver 6.3.x Series
  • Future-aware scheduling for dedicated resources
  • MPI support
  • Security enhancements
  • Secure network communication
  • Kerberos, PKI (GSI/OpenSSL)
  • Limitations on executable, remote syscall sandbox
  • Condor-G production version
  • Integrate Bypass technology
  • Enhanced Windows support

17
What else will be added in 6.3.?
  • And also several easy-to-add, user-visible
    features
  • Master agents" - helper programs spawned by the
    condor_master to aid in administration
  • Retrieving remote log, history and/or
    configuration files
  • Remote "top", "ps" and other monitoring functions

18
What will be added in 6.3.? (cont.)
  • Solution for Condor clusters on
  • Private network
  • Behind a firewall
  • New condor_starter and condor_shadow for the
    VANILLA universe on Unix
  • "NT version" will be used for Unix, too
  • Lots of new features, like transferring files
    automatically for "vanilla" jobs (no need for a
    shared filesystem)

19
What will be added in 6.3.? (cont.)
  • condor_startd will enforce resource limits
    dynamically (like RAM usage)
  • More logic put into the condor_shadow to
  • Detect temporary problems with a job's execution,
    put the job on hold, and notify the user
  • Enforce job submitting users policy
  • Better propagation of error messages

20
The 6.5. Development Series
  • 6.5. will be for adding fundamentally new
    technology to Condor
  • Being developed in parallel with 6.3.
  • Will ultimately be v7.0
  • Will be incompatible with previous versions of
    Condor

21
New Technology in 6.5.
  • New version of ClassAds
  • Conditionals !!
  • if/then/else
  • Aggregates (lists, nested classads)
  • Built-in functions
  • String operations, pattern matching, time
    operators, unit conversions
  • Clean implementations in C and Java
  • ClassAd collections

22
Other changes for 6.5.
  • Re-write of the condor_schedd
  • Performance enhancements and lowered resource
    requirements (particularly RAM)
  • Re-write of the checkpoint server
  • NEST technology infusion
  • Enhanced support for multiple servers
  • Will meta-data along with checkpoint files

23
