Hi all, I am OK if we cancel too, but at the next meeting we hold, I wanted to do an update about FA-MPI work and answer questions people have about our approach to it. Since this came up a couple calls ago. It would be fine to wait for next call slot to do this... We are actively extending FA-MPI at this time.

I'm okay if we cancel. On a different note, I wanted to ask the group about the error handler for MPI_Init. As I look into the problem of MPI re-initialization, I came across some questions, which I'm not been able to answer myself by reading the standard: - Since one cannot set an error handler before MPI_Init, is is expected that MPI_ERRORS_ARE_FATAL is enabled when MPI_Init is called? If that is the case, one can assume that if an error occurs the first time MPI_Init is called (let's assume in the future we can call MPI_Init several times), MPI will abort? - Is there any situation, in which MPI_Init could return an error code if a failure occurs? - Is there a way to set MPI_ERROR_RETURN in COMM_WORLD before calling MPI_Init?

I'm okay if we cancel. On a different note, I wanted to ask the group about the error handler for MPI_Init. As I look into the problem of MPI re-initialization, I came across some questions, which I'm not been able to answer myself by reading the standard: - Since one cannot set an error handler before MPI_Init, is is expected that MPI_ERRORS_ARE_FATAL is enabled when MPI_Init is called? If that is the case, one can assume that if an error occurs the first time MPI_Init is called (let's assume in the future we can call MPI_Init several times), MPI will abort? - Is there any situation, in which MPI_Init could return an error code if a failure occurs? - Is there a way to set MPI_ERROR_RETURN in COMM_WORLD before calling MPI_Init?

I don't have any topics for today's FTWG con call. Does anyone have anything they want to discuss? Should we cancel?

Given the lack of responses, I'll go ahead and say that today's call is cancelled. > On Jun 7, 2017, at 10:35 AM, Bland, Wesley <wesley.bland(a)intel.com> wrote: > > Hi folks, > > I haven't been able to make progress on the topics that we're currently working on.
