Re: [OMPI users] Error when using Einstein toolkit

Greetings, and welcome to the wonderful world of MPI. :-) First thing to note is that there are multiple different software packages that implement the MPI specification. Open MPI -- the mailing list that you sent to -- is one of them. MPICH, from Argonne National Labs, is another. From the

[OMPI users] Error when using Einstein toolkit

Hello, I am an undergraduate student. I have just started learning MPI and I have to use the Einstein Toolkit code which uses MPI for my project. I get this error when I try to check the output of my simulation: *Fatal error in PMPI_Comm_rank: Invalid communicator, error

Sorry, I did not see my autocorrect changed some word. I added the -l and it did not change anything. Also the mpicxx —showme does not work. It says that the option —showme does not exist Quentin On Apr 4, 2018, at 10:45, Quentin Faure >

I had the -l but it did not change anything. Also the mlicxx —showme does not work, it says that the option —showmen does not exist. Quentin On Apr 3, 2018, at 14:25, Nathan Hjelm > wrote: I guess I should point out the reason the compiler thought you had

Re: [OMPI users] running mpi program between my PC and an ARM-architektur raspberry

We can always build complicated solutions, but in some cases sane and simple solutions exists. Let me clear some of the misinformation in this thread. The MPI standard is clear what type of conversion is allowed and how it should be done (for more info read Chapter 4): no type conversion is

Re: [OMPI users] running mpi program between my PC and an ARM-architektur raspberry

Dear colleagues, FWIW, years ago I was looking at this problem and developed my own solution (for C programs) with this structure: --Be sure your code that works with ambiguous-length types like 'long' can handle different sizes. I have replacement unambiguous typedef names like 'si32', 'ui64'

Re: [hwloc-users] Netloc integration with hwloc

Brice, We don't actually care if it is a graph or a different API. We'll anyway simply parse the graph and create our own internal structures that we can map to our internal algorithms. We simply need some model (any model) to retrieve the network topology. That's it. We'll take care of

Re: [hwloc-users] Netloc integration with hwloc

I'm also interested in re-igniting the discussion, if others are also interested. I'm curious about the current state of netloc, and what we all want it to look like. Maybe we should move the discussion to the devel list or have a teleconf or something to kick things off? On Wed, Apr 4, 2018 at
