ANU presents PDE solver with ULFM at IPDPS

Mohsin Ali and Peter Strazdins presented their work on “Application Level Fault Recovery, Using Fault-Tolerant Open MPI in a PDE Solver”, during the IPDPS PDSEC workshop, last week. See the full slides for more details. This novel work joins the growing list of applications benefiting from ULFM to feature fault tolerance; more examples are presented in these applications slides. If you have worked on fault tolerant applications with ULFM, or are thinking about doing so, please contact us.

Preparing for June MPI Forum meeting

In preparation for the June MPI forum meeting, the specification has received some updates. The most prominent changes are: The exposed memory in an RMA window may be completely undefined after a failure has occured. MPI_Comm_agree now operates a binary AND on the flag argument. Examples have been corrected to use error classes, instead of error codes, when relevant. The latest version is available in the ULFM specification area
