FTHP-MPI: Towards Providing Replication-based Fault Tolerance in a Fault-Intolerant Native MPI Library
Sarthak Joshi, Sathish Vadhiyar
Faults in high-performance systems are expected to be very frequent in the current exascale computing era. To compensate for a higher failure rate, the standard checkpoint/restart…
A Scalable System for Visual Analysis of Ocean Data
Toshit Jain, Upkar Singh, Varun Singh +5
Oceanographers rely on visual analysis to interpret model simulations, identify events and phenomena, and track dynamic ocean processes. The ever increasing resolution and complexi…
PartRePer-MPI: Combining Fault Tolerance and Performance for MPI Applications
Sarthak Joshi, Sathish Vadhiyar
As we have entered Exascale computing, the faults in high-performance systems are expected to increase considerably. To compensate for a higher failure rate, the standard checkpoin…
Efficient executions of Pipelined Conjugate Gradient Method on Heterogeneous Architectures
Manasi Tiwari, Sathish Vadhiyar
The Preconditioned Conjugate Gradient (PCG) method is widely used for solving linear systems of equations with sparse matrices. A recent version of PCG, Pipelined PCG, eliminates t…
End-to-End Predictions-Based Resource Management Framework for Supercomputer Jobs
Swetha Hariharan, Prakash Murali, Abhishek Pasari +1
Job submissions of parallel applications to production supercomputer systems will have to be carefully tuned in terms of the job submission parameters to obtain minimum response ti…
A Fine-Grained Hybrid CPU-GPU Algorithm for Betweenness Centrality Computations
Ashirbad Mishra, Sathish Vadhiyar, Rupesh Nasre +1
Betweenness centrality (BC) is an important graph analytical application for large-scale graphs. While there are many efforts for parallelizing betweenness centrality algorithms on…
