The aim of the project is to create a checkpointing solution. The application, while running should be able to checkpoint itself at different interval, continue after a checkpoint is done and restart when the application [login to view URL], there should be these three functions available: checkpoint() continue() restart() The user should also have the option to put function calls in his program that will trigger the checkpointing mechnaism. That is checkpoint interval should be both user defined and automatic. The checkpoint mechanism should be able to checkpoint parallel applications with processes running on different machines. In my case it is MPI applications ( MPI applications are c applications with a set of libraries that enables parallelisation of applications. The syntax is c)

This project sounds as if you are looking to create an extended watchdog api for a suite of applications. If this is the case, I am quite familiar with this style of application and have created several unique watchdog API's for RTOS systems in the past few years. Probably the most tightly bound was a system with 128k spare SDRAM(original size of ram was 512k with a 300k+ RTOS application based on nucleus). The API I created offered registration, check-in, memory monitoring and recovery of the system with no escapes. I would also like to recommend a tiered structure where we first settle on a requirement spec, and a milestone based execution structure with you being able to verify each step. Is there a specific toolchain and/or processor that you are targeting this for, or are you expecting a generic x86 system?

Hi, I am a Ph. D. candidate in research of parallel computing, and I've already made some investigation on the breakpoint implementation. By far, I guess it is worthy of dedicated reading and thinking for perfect solution. I work on linux clusters on workstations, and MPI is one of main the tools, maybe it is similar to your development environment. Please check PMs for more detail. Thanks a lot.
