Be a mentor at PEARC17 and make a difference!

Make a difference in the lives of next-generation scientists and science leaders at PEARC17—Practice & Experience in Advanced Research Computing 2017 in New Orleans, July 9-13. As a mentor, you will give students the opportunity to learn from your expertise as they explore a variety of related issues, such as differing specialties, postgraduate training, and work/life balance; plus enjoy Monday’s complimentary student-mentor dinner. Many mentorships turn into lifetime friendships and have countless benefits.  

Check "I want to be a mentor" when you register for the PEARC17 conference, which will take place in New Orleans, July 9-13. The conference is open to professionals and students in advanced research computing. Registration for the conference and hotel are now open.

Center for Network and Storage-Enabled Collaborative Computational Science Symposium

Dear Colleagues,

Please join us May 18-19 in Ann Arbor for the first symposium of the Center for Network and Storage-Enabled Collaborative Computational Science (CNSECCS).

The symposium is intended to bring together scientists, researchers and infrastructure specialists to share experiences and best practices, and to discuss both challenges and possible solutions that enable scientists to work together on “big, distributed or diverse data”.

Speakers will come from a wide range of research domains, as well as federal funding agencies:

  * Amy Friedlander, Deputy Division Director, Division of Advanced Cyberinfrastructure (CISE/ACI), National Science Foundation.
  * Richard Carlson, Program Officer, Advanced Scientific Computing Research (ASCR), Department of Energy
  * Nina Silverberg, Program Director, Alzheimer's Disease Centers program, Division of Neuroscience, National Institutes of Health

We are also accepting abstracts from potential presenters through the beginning of April.

For more information and to register, visit:

XRootD 4.6.0 removed from OSG 3.3.22

XRootD 4.6.0 was pulled from the OSG repositories. The OSG repositories still contain XRootD 4.5.0.
XRootD 4.6.0 was in the OSG repositories from Tuesday, March 11th until Friday, March 17th.

End users encountered XRootD failures when using GSI authentication.
The problems have been traced to a defect in the CRL verification code.
XRootD running in a server mode will likely experience problems,
since reading the served file usually requires authentication.
XRootD running in the manager mode may not experience any difficulties,
since the redirector typically does not do authentication.

To check if you have the affected components installed, run
`rpm -qa | grep xrootd` to display the versions of your xrootd packages.
If any of them are version 4.6.0, run `yum downgrade <package>` on those
packages.

We are awaiting the 4.6.1 XRootD release which corrects these issues.
We will test and release it next available OSG release.

We apologize for any inconvenience. Our release testing did not catch
this problem. We are augmenting our release processes to catch this
specific problem as well as similar issues that may come up in other
packages.

GOC Service Update - Tuesday, March 28th at 14:00 UTC

The GOC will upgrade the following services beginning Tuesday, March 28th at 14:00 UTC. The GOC reserves 8 hours in the unlikely event unexpected problems are encountered.
