MPI Fault Tolerance Library

Feature list

• C/C++
• MPI 3.0
• User-level checkpoint library
• ULFM (ver 1.0 support)

• GNU/Linux
• Unit test (cxxtest framework)

Test Samples

• head-2d - Laplace equation solver by Jacobi iteration method
• n-body - an n-body simulation approximates the motion of particles, often specifically particles that interact with one another through some type of physical forces.
• midpoint-rule
• monte-carlo
• nprimes

User-level checkpoint library

• Rollback recovery - checkpoint/restart based
• Failure detection - ULFM based
• Snapshot creation - hard drive based (in place/via NFS)
• Incremental chekpointing - delta encoding based (XOR operation)
• Aditional compress procedure - zlib based

ULFM

• Survivability
• Fault-tollerance
• Compute redundancy

WIP

• Implementing alternative recovery fault tolerance methods
• Expanding test sample base
• Reducing overhead
• Improving impementation

This project has been implemented as a part of my graduate thesis in Computing Systems department of Siberian State University of Telecommunications and Information Scienses.
