Note that using the diagnostics package, even with mdsio, also allows you to have one file per timestep and `globalFiles=.TRUE.` so maybe that is good enough for you? </div><div class=""><br class=""></div><div class="">If you use MNC you will have to glue the netcdf files together. </div><div class=""><br class=""></div><div class="">You may also be interested in my PR for global netcdf files. I’m not sure what the status of it is in the project, but I use it all the time now. <a href="https://github.com/MITgcm/MITgcm/pull/31" class="">https://github.com/MITgcm/MITgcm/pull/31</a></div><div class=""><br class=""></div><div class="">Cheers, Jody<br class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Apr 11, 2019, at 12:57 PM, Yangxin He <<a href="mailto:y67he@uwaterloo.ca" class="">y67he@uwaterloo.ca</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div id="divtagdefaultwrapper" dir="ltr" style="caret-color: rgb(0, 0, 0); font-style: normal; font-variant-caps: normal; font-weight: normal; letter-spacing: normal; text-align: start; text-indent: 0px; text-transform: none; white-space: normal; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration: none; font-size: 12pt; font-family: Calibri, Helvetica, sans-serif;" class=""><div style="margin-top: 0px; margin-bottom: 0px;" class="">Hi there,</div><div style="margin-top: 0px; margin-bottom: 0px;" class=""><br class=""></div><div style="margin-top: 0px; margin-bottom: 0px;" class="">I have been using mdsio output files for a while, and globalFiles=.TRUE., so for each variable I have 2 files *.data and *.meta.<br class=""></div><div style="margin-top: 0px; margin-bottom: 0px;" class="">Now I wanna reduce my file creation rate so I am trying the MNC package. I see the netcdf packs the velocities and temperature files into one netcdf file, so I can reduce file creation by about 8. But at the same time for each cpu I get one netcdf file, currently I use 38 cpus so thats 38 netcdf files for each dumpFreq.
