Runs with nSx = 6 and nPx = 4 produce zero salinity sensitivities and other subtle differences in the adjoint, but with nSx = 1 and nPx = 6 (with 32 x 32 tiles), the adjoint runs work fine. The forward runs are nearly identical if nSx = 1 or nSx > 1, but something in the adjoint code (or TAF) gets screwed up if nSx > 1.<div class=""><br class=""></div><div class="">Caveat utilitor,</div><div class="">Christopher</div><div class=""><div><br class=""><blockquote type="cite" class=""><div class="">On Jun 28, 2018, at 10:08 AM, Christopher Pitt Wolfe <<a href="mailto:c.l.p.wolfe@icloud.com" class="">c.l.p.wolfe@icloud.com</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><meta http-equiv="Content-Type" content="text/html charset=utf-8" class=""><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><div class="">Thanks Gael.

While there are some differences related to the different model versions (66c for the included results compared to my 67b setup), most of the AD results are similar to within a couple of decimal places. The only weird thing in my case is that all the salt sensitivities are ZERO: all the ad_dynstat_adsalt fields are zero and the ADJsalt files are zeros. The adxx_salt file is written, but is zeros as well. I have verified that salinity is specifically included as a generic control in data.ctrl and the xx_salt file is written at the beginning of the forward run, so I’m stumped.<br class=""><br class="">This case is run as part of the daily testreport cases and appears to pass on glacier, but I can’t find any STDOUT files to check if the salt sensitivities remain nonzero.<br class=""><br class="">I’m not sure where to look for the source of the problem, so any advice would be appreciated. If anyone has a recent STDOUT file from this test case, I’d be interested in that as well.<br class=""><br class="">Thanks!<br class="">Christopher<br class=""><br class=""><br class=""><br class="">-----------------------------------------------------------<br class="">Christopher L.
