<p class=MsoNormal>Dear Professor Yandell,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I am Hai Wang, a visiting scholar in Cornell University. I
am sorry to bother you, but I really need your help. I am now using the maker
pipeline to annotate a maize genome. The installation of maker, openmpi and
other software should be OK since I’ve successfully run maker on your
example data.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>But when I ran maker on my own maize genome, I always got
the following error:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>A process has executed an operation involving a call to the<o:p></o:p></p>
<p class=MsoNormal>"fork()" system call to create a child
process. Open MPI is currently<o:p></o:p></p>
<p class=MsoNormal>operating in a condition that could result in memory
corruption or<o:p></o:p></p>
<p class=MsoNormal>other system errors; your job may hang, crash, or produce
silent<o:p></o:p></p>
<p class=MsoNormal>data corruption. The use of fork() (or system() or other
calls that<o:p></o:p></p>
<p class=MsoNormal>create child processes) is strongly discouraged.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The process that invoked fork was:<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> Local
host: [[21269,1],0] (PID
12537)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>If you are *absolutely sure* that your application will
successfully<o:p></o:p></p>
<p class=MsoNormal>and correctly survive a call to fork(), you may disable this
warning<o:p></o:p></p>
<p class=MsoNormal>by setting the mpi_warn_on_fork MCA parameter to 0.<o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Could you please help me with this issue? Or is there a way
that I can resume this job when it stops? Thank you very much!<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Best,<o:p></o:p></p>
