Hi
I am trying to get things right setting up simfactory on my cluster. I have created the okeanos.ini and okeanos.cfg files, as well as built the Cactus executable that's called cactus_okeanos. First I want to debug the machine setup, then I hope to take care of the submission script.
To submit a job, I use: simfactory/bin/sim create-submit GW150914_4 --parfile par/GW150914/GW150914.rpar --walltime 24:00:00 --configuration=okeanos --machine=okeanos
The error I am getting is the following:
Warning: Too many threads per process specified: specified num-threads=48 (ppn-used is 24) Warning: Number of used cores per node, number of SMT threads, and number of threads per process are inconsistent: ppn-used=24, num-smt=1, num-threads=48_threads (ppn-used*num-smt must be an integer multiple of num-threads) Warning: Total number of threads and number of threads per process are inconsistent: procs=1, num-threads=48 (procs*num-smt must be an integer multiple of num-threads) Warning: Total number of threads and number of cores per node are inconsistent: procs=1, ppn-used=24 (procs must be an integer multiple of ppn-used)
The relevant part of my machine .ini file looks like this: cpu = Intel Xeon E5-2690 v3 cpufreq = 2.6 ppn = 24 # or more max-num-threads = 48 # or more num-threads = 48 # or more nodes = 1084 memory = 131072 #any node has 128GB ram min-ppn = 24 maxwalltime = 48:00:00
I know that each node in my cluster consists of 12 sockets for cpus, each cpu has two cores and each core supports multithreading (=2), so it's 12x2x2 = 48. What am I getting wrong?
