Hello Hui -- I've somewhat lost track of your environment settings. What do you have CHPL_LAUNCHER and CHPL_COMM_SUBSTRATE set to now, and also what are the settings of all of your GASNet-specific env vars, such as GASNET_SPAWNFN and the like?

Hello, team Following up the previous issue, I've found out that was because I was missing libibverbs.so.1 in the machine. After adding that, I came to an error exactly the same as I found in an old thread in the mailing list: https://sourceforge.net/p/chapel/mailman/message/34769706/ ** FATAL ERROR: Requested spawner "(not set)" is unknown or not supported in this build WARNING: Ignoring call to gasneti_print_backtrace_ifenabled before gasneti_backtrace_init srun: error: node01: task 0: Aborted srun: error: node03: task 2: Aborted srun: error: node02: task 1: Aborted But I don't see a solution provided, so is there any method tried to fix this problem ?

Here's my script to use gasnet with slurm: export GASNET_SSH_OPTIONS="-o LogLevel=Error" #disable login banner into the output export GASNET_SPAWNFN=C export GASNET_CSPAWN_CMD='srun -N%N %C' . /hello6-taskpar-dist -nl 4 (using _real won't work, any idea why?) It works but the output suggests to use ibv-conduit instead of udp-conduit for better performance, so I did: 1) export CHPL_COMM=gasnet export CHPL_LAUNCHER=slurm-gasnetrun_ibv export CHPL_COMM_SUBSTRATE=ibv 2) cd $CHPL_HOME & make It reports the same error ashttps://sourceforge.net/p/chapel/mailman/chapel-developers/thread/VI1PR06MB118160 [email protected]/ and it builds with patch provided by Michael. However, when I recompiled hello6, then used the same script to execute it, the job completed normally but it did not output anything. If I use -v in the command, it only printed out: expect .chpl-expect-12045 Am I missing something ? Thanks -- Best regards Hui Zhang -- Best regards Hui Zhang -- Best regards Hui Zhang
