<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class="">Hello,<div class=""><br class=""></div><div class="">First post to the discussion board. I made the mistake of upgrading to macOS 11.2 (aka Big Sur). I was able to build MPICH 3.4.1 successfully and integrate it with an application. However, when I ran, MPICH crashed. Here is the initial output:</div><div class=""><br class=""></div><div class=""><div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Monaco; background-color: rgb(201, 185, 109);" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">Abort(1) on node 0: Internal error</span></div><div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Monaco; background-color: rgb(201, 185, 109);" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">0 libpmpi.12.dylib 0x00000001068c2159 MPL_backtrace_show + 57</span></div><div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Monaco; background-color: rgb(201, 185, 109);" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">1 libpmpi.12.dylib 0x000000010684e874 MPIR_Assert_fail + 36</span></div><div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Monaco; background-color: rgb(201, 185, 109);" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">2 libpmpi.12.dylib 0x0000000106897bc8 MPIDI_OFI_mpi_init_hook + 4472</span></div><div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Monaco; background-color: rgb(201, 185, 109);" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">3 libpmpi.12.dylib 0x00000001068790d3 MPID_Init + 3091</span></div><div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Monaco; background-color: rgb(201, 185, 109);" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">4 libpmpi.12.dylib 0x00000001066ae70b MPIR_Init_thread + 219</span></div><div style="margin: 0px; font-stretch: normal; font-size: 11px; line-height: normal; font-family: Monaco; background-color: rgb(201, 185, 109);" class=""><span style="font-variant-ligatures: no-common-ligatures" class="">5 libmpi.12.dylib 0x00000001064bb897 MPI_Init + 279</span></div></div><div class=""><span style="font-variant-ligatures: no-common-ligatures" class=""><br class=""></span></div>I have not yet dug into the issue any further. Before doing so I wanted to first check to see if others have successfully built and run via macOS 11.2. If so I would appreciate any pointers. If it is known that it will not yet work, that would be good information as well so not to spend anytime digging.<div class=""><br class=""></div><div class="">I should note that on another machine, I was wiser and upgraded to macOS 10.5.7 (aka Catalina) and built and ran with 3.3.1 that worked fine running in parallel.</div><div class=""><br class=""></div><div class=""><span style="orphans: 2; widows: 2; -webkit-text-decorations-in-effect: none;" class="">Cheers,</span><br class=""><div class=""><span class="Apple-style-span" style="border-collapse: separate; font-variant-ligatures: normal; font-variant-east-asian: normal; font-variant-position: normal; line-height: normal; border-spacing: 0px; -webkit-text-decorations-in-effect: none;"><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space;" class=""><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-east-asian: normal; font-variant-position: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; border-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-stroke-width: 0px;"><span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-east-asian: normal; font-variant-position: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; border-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-stroke-width: 0px;"><span class="Apple-style-span" style="border-collapse: separate; border-spacing: 0px; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-variant-east-asian: normal; font-variant-position: normal; font-weight: normal; letter-spacing: normal; line-height: normal; -webkit-text-decorations-in-effect: none; text-indent: 0px; text-transform: none; orphans: 2; white-space: normal; widows: 2; word-spacing: 0px;"><p style="margin: 0px;" class=""><br class=""></p><p style="margin: 0px;" class="">Allen</p><p style="margin: 0px;" class=""><br class=""></p><p style="margin: 0px;" class=""><br class=""></p><p style="margin: 0px;" class=""><font face="Helvetica" size="3" style="font-style: normal; font-variant-caps: normal; font-weight: normal; font-size: 12px; line-height: normal; font-family: Helvetica;" class="">Allen Sanderson</font></p><p style="margin: 0px;" class=""><font face="Helvetica" size="3" style="font-style: normal; font-variant-caps: normal; font-weight: normal; font-size: 12px; line-height: normal; font-family: Helvetica;" class="">SCI Institute</font></p><p style="margin: 0px;" class=""><font face="Helvetica" size="3" style="font-style: normal; font-variant-caps: normal; font-weight: normal; font-size: 12px; line-height: normal; font-family: Helvetica;" class="">University of Utah</font></p><br class="Apple-interchange-newline"></span></span><br class="Apple-interchange-newline"></span></div></span>
