This list is for asking questions about the usage of mpich. General<br>
programming questions like the below are better suited for a forum like<br>
Stackoverflow.<br>

Hello,<br>
<br>
how do you run your program ?<br>
e.g.<br>
./a.out <m> <base> <r><br>
which values for m, base and r ?<br>
<br>
there is no check on boundaries, and depending on the input parameters,<br>
<br>
cat[count][ cursor[count]++ ]<br>
<br>
indexes can be out of bound<br>
<br>
imho, this is not mpich related at all<br>
<br>
Best regards,<br>
<br>
Gilles<br>

It?s hard to tell, but this does indicate some problem with your communication setup. Did you verify your /etc/hosts like described on the FAQ page?<br>

<br>
HI.<br>
<br>
My environment:<br>
Two Vmware VMs with ubuntu-server12.04 OS, called mpimaster,mpislaver1<br>
they both linked to a virtual network 10.0.0.1;<br>
they can ssh to each other without password;<br>
I have disabled the fire walls with "sudo ufw disable"<br>
I install mpich3.0.4 on a NFS servered by mpimaster.<br>
<br>
I installed mpich3.0.4 follow the "readme.txt", it has Communication problem when progresses from different host comunicate with each other.<br>
