How can i make MPI process notify the others about an error for example, specially on an 开发者_C百科MPI program where all the MPI processees are independant from each others ( There no synchronisatio
If i declare a table of MPI_Request ( one request for each CPU ), it will be accessible globally when using for MPI_Isend/MPI_Irecv ?? ( In comparison with MPI_comm that is everywhere accessible after
I\'m new in MPI programming world and i\'m wondering if there is some variables shared between MPI processees and accessible from any process without ha开发者_高级运维ving to send/receive them ?
I am a beginner in MPI, and i am using C Language, and Simulator for Processors (MPICH2), i wrote the following code to send a 2D array to make 2 processors take a line from it but it produces error w
I am using开发者_如何学运维 TotalView and am getting an MPI_Error. However, Totalview does not stop on this error and I can\'t find where it is occurring. I believe this also applies to GDB.Define an
Is there an easy way to implement atomic integer operations (one sided) in mpi? last time I looked three years ago, example in mpi book was fairly complex to implemen开发者_JAVA技巧t.MPI one-sided is
I have the following problem: Program 1 has a huge amount of data, say 10GB. The data in question consists of la开发者_开发技巧rge integer- and double-arrays.
I have to admit, I was quite shocked to see how many lines of code are required to transfer one C struct with MPI.
I am trying to send a user-defined structure named ABC using boost::mpi::send () call. The given struct contains a vector \"data\" whose size is determined at runtime. Objects of struct ABC are sent
Is it poss开发者_JAVA百科ible to send a structure as a datatype in Open MPI?Yes, have a look first at MPI_TYPE_CREATE_STRUCT, or if your implementation does not include MPI-2 features, the older MPI_T
