[OMPI devel] Trunk problem: VT breakage

It appears I cannot build the trunk on Mac - I hit this issue when I updated from the trunk and rebuilt from autogen this evening: make[7]: *** No rule to make target `vt_filthandler.cc', needed by `vtfilter-vt_filthandler.o'. Stop. Vanilla configure - I didn't turn VT off like I usually do.

That's still not quite right, per OMPI conventions. If you don't find it, you shouldn't warn, you should have some other AC_MSG_CHECKING and then indicate that that particular check failed. E.g. AC_MSG_CHECKING([if can use dynamic SL support]) AS_IF([test "$1_have_dynamic_sl" = "1"],

[OMPI devel] TIPC BTL Segmentation fault

Hi, As I advanced in my implementation of TIPC BTL, I added the component and tried to run hello_c program to test. Then I got this segmentation fault. It seemed happening after the call "mca_btl_tipc_add_procs". The error message displayed: [oak:23192] *** Process received signal ***

Kawashima-san, Congratulations for your machine, this is a stunning achievement ! > Kawashima wrote : > Also, we modified tuned COLL to implement interconnect-and-topology- > specific bcast/allgather/alltoall/allreduce algorithm. These algorithm > implementations

Hi Jeff, Ralph, and all, Thank you for your reply. RIKEN and Fujitsu will work toword 10Pflops with Open MPI continuously. Here we can explain some parts of our MPI: As page 13 of Koh Hotta's presentation shows, we extended OMPI communication layers. >
