This looks like it may be a very simple fix but I honestly have no idea where to start. Sadly nothing obvious from google searches. My UPC 2.10.0 build works fine over MPI( openmpi 1.4.1 - built for GM, IBV and eth), IBV but not GM, it crashes with the following error. *** FATAL ERROR: Can't pin FAST Segment of 532.27 MB NOTICE: Before reporting bugs, run with GASNET_BACKTRACE=1 in the environment to generate a backtrace. *** Caught a fatal signal: SIGABRT(6) on node 3/4 bash: line 1: 14500 Aborted /usr/bin/env GMPI_MASTER=10.131.56.61 GMPI_PORT=8000 GMPI_SHMEM=1 LD_LIBRARY_PATH=/opt/mpi/openmpi/1.4.1/gnu/lib:/opt/myrinet/2.1.30/lib/:/opt/upc/berkley/2.10.0/gnu//lib GMPI_MAGIC=2016437 GMPI_ID=0 GMPI_NP=4 GMPI_BOARD=-1 GMPI_SLAVE=10.131.56.61 GASNET_SSH_SERVERS="vogon41.deepthought.hpsg.dcs.warwick.ac.uk vogon41.deepthought.hpsg.dcs.warwick.ac.uk vogon40.deepthought.hpsg.dcs.warwick.ac.uk vogon40.deepthought.hpsg.dcs.warwick.ac.uk" GASNET_GASNETRUN_GM=1 UPC_NODES="vogon41.deepthought.hpsg.dcs.warwick.ac.uk vogon41.deepthought.hpsg.dcs.warwick.ac.uk vogon40.deepthought.hpsg.dcs.warwick.ac.uk vogon40.deepthought.hpsg.dcs.warwick.ac.uk" /home/fjp/Graphs/UPC/./floyd2-parallel '8000' GASNET_BACKTRACE=1 Adds this extra information *** FATAL ERROR: Can't pin FAST Segment of 532.27 MB [3] /usr/bin/gdb -nx -batch -x /tmp/gasnet_IXY5Ly '/home/fjp/Graphs/UPC/./floyd2-parallel' 10899 [3] [Thread debugging using libthread_db enabled] [3] [New Thread 0x403190c0 (LWP 10899)] [3] 0x401cf3ae in __waitpid_nocancel () from /lib/libpthread.so.0 [3] #0 0x401cf3ae in __waitpid_nocancel () from /lib/libpthread.so.0 [3] #1 0x4005946c in system ( [3] cmd=0x8115ac0 "/usr/bin/gdb -nx -batch -x /tmp/gasnet_IXY5Ly '/home/fjp/Graphs/UPC/./floyd2-parallel' 10899") at ./libgm/gm_fork_system.c:227 [3] #2 0x080a01ad in gasneti_bt_gdb () [3] #3 0x080a27fb in gasneti_print_backtrace () [3] #4 0x080a0446 in gasneti_fatalerror () [3] #5 0x0809130d in gasnetc_attach () [3] #6 0x08069ee3 in upcr_startup_attach () [3] #7 0x0807de2e in bupc_init_reentrant () [3] #8 0x08061698 in main () [0] /usr/bin/gdb -nx -batch -x /tmp/gasnet_qB0Wxz '/home/fjp/Graphs/UPC/./floyd2-parallel' 14630 Program compiled with `upcc -shared-heap=900 -network=gm` Regards Oliver Perks -- Oliver Perks CS204 Department of Computer Science University of Warwick
