Hi everyone, I’m attempting to build CADET v4.2.0 on a Linux machine (running Ubuntu 20.10). I installed CADET following the directions packaged with the source code (BUILD-LINUX.md), and I didn’t receive any errors (output is given in the attached file). However, when I run cadet-cli with a .h5 fi…

The fix is provided in commit Fix _nThreads lower bound to 0 (#83) · cadet/CADET-Core@c832f68 · GitHub . Please get the most recent source ( https://github.com/modsim/CADET/archive/refs/heads/master.zip ) and compile again.

Hi Chase, it looks like CADET was compiled correctly. The log you’ve posted seems clean (just a side note: we recommend using MKL in serial mode, i.e., Intel10_64lp_seq). In order to debug this problem, it would be great if you could provide the .h5 file that triggers this error. Best, Sam

Hi Sam, Thank you for your help! Attached is the .h5 file, along with the notebook used to generate it. Thank you, Chase test_case.h5 (34.5 KB) test_case_no_imports.ipynb (13.8 KB)

It seems to run on my Windows box (at least in a debug build). Will try it on my Unix box later. Results from the Windows run: test_case.h5 (96.9 KB)

For me, it also runs in DEBUG mode, but not in RELEASE. OS: Ubuntu 20.04 cmake version: 3.16.3 gcc version: 9.3.0

[image] j.schmoelder: For me, it also runs in DEBUG mode, but not in RELEASE. This hints at a TBB problem: In debug mode, TBB is not used.

Thanks to @j.rao and @j.schmoelder , we figured out the following quick fix: Set NTHREADS to 0 (or a positive number). Do not use a negative number. Background: NTHREADS is read as int but converted to unsigned int at some point. Since NTHREADS was set to -1, the conversion wrapped around to a ridi…
