 Posted: Mon Jan 20, 2025 10:45 pm Post subject: Why building sci-libs/rocFFT-6.1.1 takes so long? |
 |
|
I am currently building the sci-libs/rocFFT-6.1.1 on my 32-core, 64G memory machine.
The build process has already lasted for 24 hours, and I have no idea when it will be completed.
The system load has been consistently ranging from 5.0 to 10.0.
As indicated by the top command, it seems that rocfft_aot_help process is managing the build process, with clang (multiple processes run in parallel) being involved only intermittently.
Is this situation normal?
What is the typical build time for rocFFT?
I have enabled all amdgpu_targets, does it matter?

Finally, it completes. I guess it takes a total of 36 hours.

Maybe there will be an update in the portage tree tomorrow. Or it has to be rebuilt because a required library has been updated.  |

Good to know. The file you mentioned (temp version in temp build directory) is at 843MB and it's been 9 hours so far.
I am running xeon e3-1275 with 16GB ram. So at least 36 hrs huh  |
