[mpich-discuss] MPICH2-1.3.1 crash and SIGHUP issues.

[Sunil Thomas]

Hi,

  I noticed that a simple test example code (just one C file) that used to
run in parallel with an older installation of MPICH2
(1.2.7 if I recall correctly) no longer runs with the latest stable release
version (1.3.1). The following is the error I am getting:

*$>mpiexec -f machinefile -n 2 ex5_hypre
APPLICATION TERMINATED WITH THE EXIT STRING: Hangup (signal 1)*

  When I switch to my actual application (which basically solves a sparse
system of linear equations) and try to run that
on 2 processors, it crashes due to a memory access fault error as follows:

*unknown location(0): fatal error in ....: memory access violation at
address: 0xfffffffe03bce414: no mapping at fault address*

   It seems like the two are related. Both run just fine on 1 processor. Has
anyone seen these issues and know a fix? Many
thanks!
