host code

[ysreea]

Hi,
When I tried to run the zsim code for host.cfg(./build/opt/zsim tests/host.cfg).It's not generating multiple traces for multiple cores. But pim.cfg seems like working fine though. Can someone please let me know what might be the possible thing I'm missing here.

Hi, I'm facing the same issue.
Setting the merge_hostTraces knob to either true or false raises an error.
Any updates?

I meet the same problem, and i did not find the way to solve it.

@dchakra336 : For host processing versus pim processing, you need to run Ramulator a little bit different. You can run Ramulator with split traces to be true or split traces to be false.
I did this for my runs and it works fine.

@maryam1364: That's great! How did you run it differently?

When there is one trace file, run ramulator without --split-trace option!

Hi, the host code is always generated into a single file to ensure that the DRAM memory requests are ordered following the application's memory access pattern when simulating the host configuration on Ramulator. Recall that host traces are filtered by L3 in zsim and are intended to be used to simulate only the memory device on Ramulator (without PIM cores). Therefore, there is no reason to split host traces per core id.

I would advise to not use split traces for host code. Also, I would advise to not run host traces on PIM mode in Ramulator.

Hi,
if i follow your configuration on Ramulator,i can't get host.stats to compare with pim.stats . So how can i get the host.stats ?
Thanks!

@maryam1364 hi ,when i run ramulator without --split-trace option,i get a meaningless stats file. 😭 is there any problem ?

@XDUFanYang : For host run: it creates one ".out" file and when I want to run Ramulator, I make sure that split-traces option is false.
For PIM run: it creates 4 ".out" file. and when I run Ramulator, I makes sure that split-trace option is true.

I was working with ramulator-pim 6 months ago and these are the things I remember.

Thx, I got!
