Hi Krishna, That is good to know. How did you even know about PERUSE? (I didn't think it was that well known.) How much of the interface have you implemented? We are interested in knowing more about what you have done. Regards, Rajeev _____ From: Krishna Chaitanya [mailto:[email protected]] Sent: Thursday, March 13, 2008 7:51 AM To: [email protected] Cc: [email protected]; [email protected] Subject: Development of the PERUSE interface for MPICH2 Hi, As my final year B-Tech project, I have been working on developing the PERUSE <http://www.mpi-peruse.org/> interface for MPICH2. PERUSE is an attempt to expose fine-grained information about the internals of an MPI implementation by monitoring certain events of interest and the time elapsed between such events. The interface allows the user to define a set of events and register callbacks, which are to be invoked by the MPI library as and when an event of interest occurs. PERUSE has been successfully integrated with Open-MPI. I have the prototype working for blocking and non_blocking mode of data transfer with the sock device. I have experimented with a few examples having multiple senders and a slow receiver and have been able to generate meaningful output. Since the data generated is quite voluminous, I am now trying to present it in a graphical,user friendly manner. I wish to have your feedback on this project to look at the possible areas of improvement and further work. Please let me know if you are interested. Thanks, Krishna Chaitanya K, Final Year B-Tech, Dept. of Information Technology, National Institute of Technology,Karnataka, India. -- In the middle of difficulty, lies opportunity
