January, 2015: The talks that Saurabh gave at IIT Kharagpur are available from our presentations page. [ html ]

November, 2014: DCSL is looking for a post-doctoral researcher in the broad area of practical distributed systems, to start from January 15, 2015. Take a look at the announcement. [ html ]

August, 2014: DCSL's work with Lawrence Livermore National Lab (LLNL) is highlighted in an article appearing in their Science & Technology Review magazine for July/August 2014 with the title "Supercomputing Tools Speed Simulations". The Purdue contribution has been through Subrata and Ignacio (now an employee at LLNL) and is for the tool called AutomaDeD, which applies statistical learning to identify and diagnose performance problems in large-scale scientific applications.

August, 2014: DCSL gets 4 research awards - two from NSF (CRI and NeTS programs) and two from Department of Energy, through Lawrence Livermore National Labs. So we are now looking to hire 2 Graduate Research Assistants. If you are a starting graduate student at Purdue ECE or CS and are interested, please read the announcement of these two positions. [ Announcement ]

August 9, 2014: Two PhD graduates from DCSL - Bowen Zhou and Fahad Arshad - are ready to go on to great things in the industrial world. Another graduate, Benjamin Kobin, who graduated with an MS degree, had already left to join his job and so is not in the picture.

June 20, 2014: Our submission to Supercomputing is accepted. The paper is on parallelization of the computational genomics application called BLAST, which is used for alignment of genomics sequences. We show the insight behind fine-grained parallelization of genomics alignment and an implementation in Hadoop that shows significant improvement over the state-of-the-art parallel application. The authors are: Kanak Mahadik, Somali Chaterji, Bowen Zhou, Milind Kulkarni, and Saurabh Bagchi. It is based on our NSF-funded XPS project that started in Fall 2013. The paper is here. [ pdf ]

June 10, 2014: The code for parallel application debugging, the system called AutomaDeD, which was described in our PACT '12 and recent PLDI '14 paper (system was called "Prodometer" here) has been publicly released on github. This implementation was spearheaded by Subrata Mitra and Ignacio Laguna (DCSL member and now at LLNL).

February 22, 2014: Our paper titled "pSigene: Webcrawling to Generalize SQL Injection Signatures" is accepted to DSN, the 44th Annual IEEE/IFIP International Symposium on Dependable Systems and Networks. This work shows how to learn from a corpus of SQL injection attacks using machine learning techniques, bi-clustering and logistic regression, and match against new attacks. This is work done by DCSL researchers Gaspar (who graduated in 2013 and is now working for Narus Networks/Boeing), Fahad, Chris, and Saurabh, and our machine learning collaborator, Alan Qi. 

January 2014: DCSL gets an award from the Trask Fund for Technology Commercialization. This fund is administered by Purdue's Office of Technology Commercialization (OTC) and is meant to make a Purdue technology more commercially marketable. In this  funding cycle, our project titled "Achieving Predictable Performance on the Public Cloud" was awarded as one of three projects. The project funding is decided based on a written proposal and a presentation to a group of Purdue inventors and entrepreneurs. There are two funding cycles each year in this program. Subrata and Amiya are working on this project. [ Purdue University news story ] [ Yahoo Finance news story ]

February 3, 2014: Our first PLDI paper is accepted. This is on debugging hangs and performance problems in parallel applications through dynamic monitoring. This is work spearheaded by Subrata in collaboration with LLNL. [ pdf ]

January 22, 2014: To all those who wrote in asking about the safety of DCSL members in view of the tragic shooting in the Electrical Engineering (EE) building yesterday, thank you. And thankfully, we are all safe. [ Read more ]

November 11, 2013: Saurabh is selected as an ACM Distinguished Scientist. The ACM Distinguished Member Recognition Program recognizes those members with at least 15 years of professional experience who have made significant accomplishments or achieved a significant impact on the computing field. Distinguished Member is a member grade recognizing up to 10% of the top ACM members. In 2013, ACM elevated 40 of its members to Distinguished Member status. Saurabh was nominated for laying the software basis for designing distributed systems that can tolerate faults under a variety of operating conditions.
