<DIV>Hi,</DIV>

<DIV>&nbsp;</DIV>

<DIV>I&nbsp;have&nbsp;been&nbsp;using&nbsp;wrf&nbsp;for&nbsp;a&nbsp;couple&nbsp;of&nbsp;years&nbsp;in&nbsp;serial&nbsp;mode&nbsp;but,&nbsp;now,</DIV>

<DIV>I'd&nbsp;like&nbsp;to&nbsp;learn&nbsp;something&nbsp;about&nbsp;smpar&nbsp;and&nbsp;dmpar.&nbsp;I&nbsp;have&nbsp;a&nbsp;couple&nbsp;of</DIV>

<DIV>questions&nbsp;and&nbsp;I&nbsp;thank&nbsp;you&nbsp;in&nbsp;advance&nbsp;any&nbsp;help.</DIV>

<DIV>First,&nbsp;I'm&nbsp;wondering&nbsp;if&nbsp;it&nbsp;makes&nbsp;sense&nbsp;to&nbsp;run&nbsp;wrf&nbsp;in&nbsp;smpar&nbsp;o&nbsp;dmpar</DIV>

<DIV>mode&nbsp;in&nbsp;a&nbsp;intel&nbsp;i5&nbsp;or&nbsp;i7.&nbsp;I&nbsp;don't&nbsp;know&nbsp;if&nbsp;smpar&nbsp;and&nbsp;dmpar&nbsp;are&nbsp;only&nbsp;for</DIV>

<DIV>clusters.</DIV>

<DIV>The&nbsp;second,&nbsp;is&nbsp;if&nbsp;I&nbsp;need&nbsp;to&nbsp;have&nbsp;two&nbsp;compilations&nbsp;of&nbsp;netcdf:&nbsp;the</DIV>

<DIV>serial&nbsp;version&nbsp;and&nbsp;the&nbsp;parallel&nbsp;version,&nbsp;this&nbsp;with&nbsp;hdf5&nbsp;parallel,&nbsp;zlib</DIV>

<DIV>parallel&nbsp;and&nbsp;wrf&nbsp;built&nbsp;with&nbsp;the&nbsp;same&nbsp;mpicc&nbsp;compilers.</DIV>

<DIV>&nbsp;</DIV>

<DIV>Thank&nbsp;you&nbsp;very&nbsp;much.</DIV>

<DIV>====================================================</DIV>

<DIV>&gt;my opinion are:</DIV>

<DIV>&gt;1,It does make sense, I tested on a I5, 4core, with smpar, really much 

fast then serial.</DIV>

<DIV>&gt;2,I think serial version NetCDF lib is OK, but I didn't test parallel 

version.</DIV></DIV></BODY></HTML>
