I&#039;ve recently moved from SMP-single precision to HPC-DMP-Intel MPI to reduce runtime. However, the results I &#039;m getting from DMP is highly different from SMP, though the k. files are exactly the same. Which of these two has to be trusted? The FEM\/SPH model that I verified with SMP, and published, is now working differently using DMP and is giving me different results! I&#039;m worried since I&#039;m not able now to use my previously-verified model using DMP, though I&#039;ve paid more money? How can I get the same trustable results as SMP using DMP?<\/p>\n<p>Looking forward to hearing from you. Best.<\/p>\n","protected":false},"template":"","class_list":["post-168714","topic","type-topic","status-closed","hentry","topic-tag-DistributedMemoryParallel-1","topic-tag-DMP-2","topic-tag-SharedMemoryParallel-1","topic-tag-SMP-1"],"aioseo_notices":[],"acf":[],"custom_fields":[{"0":{"_btv_view_count":["3887"],"_bbp_likes_count":["0"],"_bbp_subscription":["237793"],"_bbp_topic_status":["unanswered"],"_bbp_status":["publish"],"_bbp_topic_id":["168714"],"_bbp_forum_id":["27814"],"_bbp_engagement":["178074","237793"],"_bbp_voice_count":["2"],"_bbp_reply_count":["1"],"_bbp_last_reply_id":["212501"],"_bbp_last_active_id":["212501"],"_bbp_last_active_time":["2022-04-21 19:22:22"]},"test":"mohammadmahdi-nekahiryerson-ca"}],"_links":{"self":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/168714","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics"}],"about":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/types\/topic"}],"version-history":[{"count":0,"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/topics\/168714\/revisions"}],"wp:attachment":[{"href":"https:\/\/innovationspace.ansys.com\/forum\/wp-json\/wp\/v2\/media?parent=168714"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
