OSG 1.2.20 Release Notification

OSG Operations and Integration are pleased to announce the release of OSG version 1.2.20.

OSG 1.2.20 Update Notification

Date: June 30, 2011

Affected Components

The following components are affected:

* All RSV installations
* CE installations


Due to the fourth of July holiday weekend, OSG support
resources will be limited so admins may want to wait until
Tuesday July 5th before updating.
This release contains the following updates:

* Several gatekeeper changes for CMS
* Optional re-nicing of the globus-gatekeeper to give it a
lower priority to keep the gatekeeper more responsive under heavy
* Random sleep for fork jobs to prevent unwanted synchronization
of grid monitor processes

* Condor job manager changes to support group accounting
* SGE job manager changes to use a more reliable polling method
* Cleanup scripts are now provided by VDT so that files left by
globus in user home directories can be removed automatically

Several other updates are also included in this release, see
the VDT update page for more details.

Update Instructions
Update instructions can be found on the OSG Twiki under the OSG
1.2 update instructions (

Additional Information

The release notes for the VDT 2.0.0p27 release underlying this
release can be found here ( ).

LIGO Needs Your Opportunistic Cycles

OSG Resource Providers,

The LIGO VO ( is looking for cycles. LIGO is currently running on approximately one-third of the OSG Resources and is ready to expand to more. Please take a look to see if your resource is enabled to allow LIGO VO jobs, and if it is not please consider enabling it. Below is a description of the application. LIGO has a strong application group that will work closely with resource providers to get the Einstein at OSG Application running. If you'd like to help please enable the LIGO VO and contact to let us know you'd like LIGO to run at your site. We are more than happy to provide assistance with enabling the VO or getting the application working on your site.

Thank you in advance for your participation,
Rob Quick
OSG Operations Coordinator
Robert Engel
LIGO Application Developer

About E@OSG

Einstein@OSG is software written to allow BOINC projects such as Einstein@Home to be executed in Grid environments. Initially developed at the Max-Planck-Institute for Gravitational Physics in Germany it is running today on the German D-Grid and the Open Science Grid. The software consists of a server scheduling and submitting jobs to grid resources and a client monitoring and executing the Einstein@Home client. Einstein@OSG has completed hundred's of million cpu hours on a vast number of heterogeneous grid resources mainly by utilizing available idle cycles.

E@OSG Execution on the OSG

The client supports following important features:

* ability to run on heterogeneous clusters providing i386 and x86_64 worker node architectures
* execution in $OSG_WN_TMP to avoid utilizing the network file system
* checkpointing on external SRM resources as well as network file systems such as NFS
* full support for eviction of jobs, automatic suspend and restart of the job
* automatic error detection and recovery of jobs
* support for GPU acceleration when available
* fine grained control about the client run-time (minutes to days) and scheduler (1 to 1000s of jobs)

which allows LIGO to utilize all compute elements currently available to LIGO to run jobs:

Benefits of running E@OSG on your Site

E@OSG continuously runs on many OSG resources mainly utilizing idle cycles that otherwise might be wasted. Our automatic error detection also informs us quickly about errors on grid resources, such as:

* lost mounts on worker nodes
* misconfigured firewalls on worker nodes
* failing GRAM and GridFTP services
* wrong set permissions on SRM and NFS directories

By opening GOC tickets we can quickly inform the resource provider about problems on the resource that otherwise might be unnoticed.

Welcome to the NEES Project and Enabling their VO for Use

OSG Collaborators,

Please join us in welcoming the George E Brown Network for Earthquake Engineering Simulation (NEES) VO to the OSG community! NEES is a shared national network of 14 experimental facilities, collaborative tools, a centralized data repository, and earthquake simulation software. Together, these resources provide the means for collaboration and discovery in the form of advanced research based on experimentation and computational simulations of the ways buildings, bridges, utility systems, coastal regions, and geomaterials perform during seismic events.

OSG User Support has worked with this VO for several months by helping them integrate their applications with OSG. We would like to ask opportunistic sites to grant NEES access to resources. Information about their work and science is available at

NEES has been recently added to the VO Package. We urge you to update to this new VO package to enable the NEES VO for opportunistic use. Instructions for doing this can be found here:

Thank you in advance for your support of this new OSG VO.

MyOSG DNS Resolution Issue

At approximately 3:00pm Eastern time the Indiana University DNS administrators erroneously removed from their DNS servers. The service was unavailable at but could be reached via and This problem was fixed by DNS administrators at 4:00pm Eastern time. We apologize for any inconvenience this has caused.

Intermittent problem with MyOSG

Between 14:50 and 15:10 UTC one instance of MyOSG (myosg2) experienced a spike in memory usage.
Some users may have encountered slow response times during this period. We believe the problem
was transitory in nature and is currently not effecting service. As a precaution, the effected
instance will be removed from DNS round robin at noon eastern time. The memory allocated to
this machine will be increased and the process repeated on the remaining instance. We do not
anticipate visible interruption of service during this process.
