Hello, I have build megakv and benchmark exacutable app successfully. And ./megakv run OK, but when I run sudo ./build/benchmark meet errors:

EAL: Detected 16 lcore(s)
EAL: No free hugepages reported in hugepages-1048576kB
EAL: Probing VFIO support...
benchmark: /home/wei/GPPIM/MegaKV/megakv/benchmark/benchmark.c:733: main: Assertion `nb_ports == 1' failed.
Aborted

Is there any configuration to solve this problem? thank you.

@alphaRGB I honestly don't know - https://github.com/pzrq/megakv/blob/master/src/include/mega_config.h looks like it might be "config"?

What environment are you running this on? Your local machine, AWS or something else?

Sorry I can't find the fork this came from at the moment, or the whitepaper, which probably had more details.

If it's helpful to you happy to accept PRs, though you may be better off forking it with any updates or fixes that work for you and your environment.

I have run benchmark on local machine, with ubuntu 18.04, with 2 intel CPUs + 2 NVIDIA V100 GPUs + 265G Memory. And I have an another question：

I want to get the 3 results of the experiments in paper- megaKV: https://dl.acm.org/doi/pdf/10.14778/2809974.2809984 :
Figure 13: Theoretical Maxium Speed for One GPU ~ Figure 15 Mega-KV Performance with Large Key-Value size.
But I down't find where to set the （Scheduling Cycles C (us) in code ? is this variable ?

megakv/src/macros.h

Line 41 in c41f259

#define NUM_SCHED_INS_DEL 0

, can I set it to 120, 140, 160 directly like the Figure 14 in paper when I run this executable app:

megakv/src/mega.c

Line 523 in c41f259

int main(int argc, char*argv[])
