[mpich-discuss] Assertion failed

[Xavier Olive]

Hello,

 I tried to recompile again that version (instead of the ubuntu
package), and I have maybe more explicit error...

Fatal error in MPI_Iprobe: Other MPI error, error stack:
MPI_Iprobe(121)...........................:
MPI_Iprobe(src=MPI_ANY_SOURCE, tag=MPI_ANY_TAG, MPI_COMM_WORLD,
flag=0x90986da4, status=0x906e2878) failed

The line with "Assertion failed in file ch3_progress.c at line 431:
conn->pkt.type < MPIDI_CH3_PKT_END_CH3" moves randomly inside that
message...

Since I use the Java wrapping and nothing is raised there, all this
looks Chinese for me...

Thanks for your concern,
Xavier
