Pl gide me if you might get soluction for this matter.</blockquote><br>
This is usually a problem in the user's program, not in MPICH
itself. What is happening is that the p4 subsystem in MPICH is
catching and reporting the signal. A SIGSEGV often means an invalid
pointer or out-of-range array index. <br><br>

<b>Good morning,<br><br>
I'm not sure about this MPICH P4 error. Could someone
help<br>
me figure out what it's telling me? The errors are:<br><br>
<br>
p0_12123: p4_error: interrupt SIGSEGV: 11<br>
p3_30694: p4_error: interrupt SIGSEGV: 11<br>
p8_448: p4_error: interrupt SIGSEGV: 11<br>
p6_31167: p4_error: interrupt SIGSEGV: 11<br>
p4_31503: p4_error: interrupt SIGSEGV: 11<br>
p2_30683: p4_error: interrupt SIGSEGV: 11<br>
p9_459: p4_error: interrupt SIGSEGV: 11<br>
p7_31178: p4_error: interrupt SIGSEGV: 11<br>
p5_31514: p4_error: interrupt SIGSEGV: 11<br><br>
This is for a job with 10 processors (rank 10). It looks like<br>
all the processes save p1 are getting this SIGSEGV error<br>
(although p1 might be getting it and I'm just not seeing in<br>
the output file).<br><br>
TIA,<br><br>
