Re: Prolematic parallel calculation on certain workstations

Just confirming that this fixes the issue. Memory utilisation is stable (increases <100mb over 100 depletion steps) with 20000 neutrons. Thanks!

Hi Jaakko, Please see the attached. I've included the modified burnupcycle.c with MISC_MEM0...MISC_MEM10 inserted as you suggest, the output (sorry, only the MISC_MEM* printouts, as the entire output is too large to upload!), and my input file (run with -omp 32). It seems like the memory usage incre...

Hi, Memory usage increases exponentially with burnup. The attached plot shows burnup vs MISC_MEMSIZE from the .res output, with 150gb after 130 steps. I compiled using icc 17.0.4, with "CFLAGS += -DMPI" disabled the Makefile. I am running on a HPC, on a single node (allocated exclusively to my Serpe...
