ab: Summary: Current approaches for checkpointing assume system homogeneity,
    where checkpointing and recovery are both performed on the same
    processor architecture and operating system configuration. Sometimes it
    is desirable or necessary to recover a failed computation on a
    different processor architecture. For such situations checkpointing and
    recovery must be portable. We argue that source-to-source compilation
    is an appropriate concept for this purpose. We describe the compilation
    techniques developed for the design of the c2ftc prototype, which
    enables machine-independent checkpoints by automatic generation of
    checkpointing and recovery code. Sequential C programs are compiled
    into fault tolerant C programs, whose checkpoints can be migrated
    across heterogeneous networks, and restarted on binary incompatible
    architectures. Experimental results on several systems provide evidence
    that the performance penalty of portable checkpointing is negligible
    for realistic checkpointing frequencies.
