When I run the program, like this: sudo ./obj/tester -v -V ff -T 00 --no-overwrite. a segmentation fault is displayed. My system is Ubuntu20.04. Why is this?

Keep allocating hugepages

@tajiaodavid I have enabled the hugepages with 1G size. Could you please give more details? thanks

Hi @erikvdk @van-ema @tajiaodavid,
I got the same error as @HxJi and also enable the hugepages with 1G size following comsec-group/blacksmith#2 (comment). The DRAM layout is below. Based on my understanding, it may be caused by the value ROW_SIZE -1. Could you please give more details? Thanks

DRAMLayout      g_mem_layout = {{{0x2000,0x200040,0x440000,0x880000,0x1100000}, 5}, 0xffff000000, ROW_SIZE-1};

Hi @TheSilentDawn,
Have you resolved the issue?
I'm experiencing a similar error with my CPU's DRAM function which is the same as yours, just like @HxJi.
Any help would be appreciated.
Thanks.
