Two Papers Were Accepted at SC 2014

Congratulations to Judi, Xin and Jim (former postdoc in the group, now at Intel) for driving the following papers that were accepted at SC 2014:

“Nonblocking Epochs in MPI One-Sided Communication”, Judicael Zounmevo, Xin Zhao, Pavan Balaji, William Gropp, and Ahmad Afsahi

“MC-Checker: Detecting Memory Consistency Errors in MPI One-Sided Applications”, Zhezhe Chen, James Dinan, Zhen Tang, Pavan Balaji, Hua Zhong, Jun Wei, Tao Huang, and Feng Qin

Special congratulations to Judi and Xin for having their paper selected as one of the best paper finalists.  The final decisions on the best paper will take place at the conference, taking both the reviews and the presentation into account.

The second paper was something Jim started while he was at Argonne, and pursued it even after he moved to Intel.  It’s great to have that work published.

Parallel Programming with MPI Tutorial @ Argonne

The Mathematics and Computer Science division at Argonne National Laboratory organized a full-day tutorial on “Parallel Programming with MPI”. The day-long, public tutorial took place on the Argonne campus (TCS Conference Center, Building 240, Room 1416), Friday, June 6th, from 9:00am till 5:30pm. The tutorial covered an introduction to MPI (morning) as well as advanced concepts in MPI (afternoon). More details are available at the tutorial website.

Followings are some pictures from the tutorial.
