Please teach me how to fix it. thanks

I have solve this problem, but another one is here.

It looks like your libtorch_cuda wrongly links to the libnccl.so under MATLAB rather than cuda. Can you avoid /usr/local/MATLAB directory to be searched in $PATH?

[Gelisi]

Morning professor! Sincerely thank you for your help. I have run the demo and I get the placement of the demo adaptec1.log. (1) Is My dreamplace 4.1.0 ? But the project mentioned the HPWL is much lower than mine. Waiting for your help. It's my first time to do this topic. Sorry to bother you
adaptec1.log

[limbo018]

The log looks OK. You can use git status to see which commit the code is. The tool does not report the version number at runtime.

Which baseline are you comparing too? If you are comparing with some numbers in published papers, they may use other tools to report HPWL, like NTUplace3 or NTUplace4dr.

[Gelisi]

This result in your readme? I just git the code days before. I think it's the newest one?

[Gelisi]

But the result in log is about [INFO ] K-reorder time: 888.724 ms

I think you need to modify the benchmarks by removing the FIXED and FIXED_NI keywords in each case to make fixed terminals and IO pads movable.

@Constwelve Please double check if this is the correct way.

[Gelisi]

so download in this way is not correct?
How can I download the modified ISPD2005 benchmarks with all fixed macros and IO pads regarded as movable.

[limbo018]

See #195 (comment)

You need to modify the case a little bit.

[Gelisi]

where can I modify the benchmarks by removing the FIXED and FIXED_NI keywords…

[limbo018]

Open the input .pl, .nodes files with any text editors.

[Gelisi]

Here, do we need to remove the keyword "fixed" from all files ending with ".pl"? And in the "nodes" section, only the keyword "terminal" is present, so it doesn't need to be touched, right?

[Gelisi]

there are many .pl files

Professor I have get the result, it seems that my result is the same as Dreamplace 4.0

[Constwelve]

Hi, we have uploaded the modified ISPD2005 benchmark. You can download it from here.

Hi, we have uploaded the modified ISPD2005 benchmark. You can download it from here.

@Constwelve could you modify the README and add this link?

[Gelisi]

But I can't open this link~~~~https://www.dropbox.com/scl/fi/01jvzui9hv0aa4krnd8lm/ispd2005free.zip?rlkey=ijwspusl9onncnsu5j4na4tqe&st=l44f3dnw&dl=0

You need 科学上网 to access dropbox.

[Gelisi]

已经挂了laddar了啊

[Gelisi]

不然git都很卡

[Constwelve]

Try this one

[Gelisi]

@Constwelve could I please have your wechat, we want to do a search on this project about the optimizer~~~~

[Constwelve]

Sure. You can send me your WeChat ID by email.
