<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br></p>I am wondering whether the -memory_info option and the <a href="http://www.mcs.anl.gov/petsc/petsc-as/snapshots/petsc-current/docs/manualpages/Sys/PetscMemoryGetMaximumUsage.html#PetscMemoryGetMaximumUsage"><span style=" text-decoration: underline; color:#0057ae;">PetscMemoryGetMaximumUsage</span></a>() call report different things.<br>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br></p>The reason i am asking is because i call the PetscMemoryGetCurrentUsage fcn in my code and it shows:<br>
5.25558e+08.<br>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br></p>At the end of the run the -memory_info option reports:<br>
max process malloc()'ed: 4.00524e+08<br>
max petsc malloc()'ed: 1.15254e+08.<br>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br></p>So i am a little confused by those numbers unless the fcn call is the more complete picture (as said on the manual page)<br>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br></p>I guess then my question is whether the -memory_info corresponds to the PetscMalloc* fcns?<br>
<p style="-qt-paragraph-type:empty; margin-top:0px; margin-bottom:0px; margin-left:0px; margin-right:0px; -qt-block-indent:0; text-indent:0px; -qt-user-state:0;"><br></p>thanks<br>
