<p class="MsoNormal">To whom it may concern,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I would like to run PETSc in a multi-threaded way (KSP per thread). I checked PETSc’s manual and it says:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">There is an OpenMP thread-safe subset of PETSc that may be configured for using --with-threadsafety [--with-openmp or --download-concurrencykit].<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am confused about the square bracket here. Does this mean I need to --with-threadsafety +( --with-openmp/--download-concurrencykit) or this mean I can add --with-threadsafety or --with-openmp or --download-concurrencykit?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Looking for your explanation on these flags!<o:p></o:p></p>
