I want to send vectors of myclass between nodes. But myclass has arrays inside of it. So i defined Datatype mpi_arrays to define the arrays in myclass and then i defined another Datatype for vectors. When i send vectors between nodes i get this error:
[localhost:31457] *** Process received signal *** [localhost:31457] Signal: Segmentation fault (11) [localhost:31457] Signal code: (128) [localhost:31457] Failing at address: (nil) [localhost:31457] [ 0] /lib/tls/libpthread.so.0 [0x84ba90] [localhost:31457] [ 1] a.out(_ZSt13__destroy_auxIP3BoxEvT_S2_12__false_type+0x19) [0x805a4f9] [localhost:31457] [ 2] a.out(_ZSt8_DestroyIP3BoxEvT_S2_+0x1a) [0x8059650] [localhost:31457] [ 3] a.out(_ZNSt6vectorI3BoxSaIS0_EED1Ev+0x1a) [0x80588d2] [localhost:31457] [ 4] a.out(_Z13GenerateBoxesv+0xe01) [0x8056055] [localhost:31457] [ 5] a.out(main+0x38) [0x8056d08] [localhost:31457] [ 6] /lib/tls/libc.so.6(__libc_start_main+0xd3) [0x13cde3] [localhost:31457] [ 7] a.out(__gxx_personality_v0+0x81) [0x8054fa9] [localhost:31457] *** End of error message *** I am a confused about what am i doing wrong and how to fix errors. It shows that i receive the vector, but then it crashes. The way i define arrays is by using contiguous, and vectors also using contiguous. Thank you for talking a look.
