Hi R.,

I just made a copy of the libm.so library from 7.

Alma is the same downstream from RHEL as Rocky. Most hpc’s will be switching to one of these (Harvard is moving to Rocky). 

Thanks,
Mitch

We don’t use Alma OS which I believe is somewhere downstream from the official RedHat CentOS8 Stream distribution, i.e., the libs may not be the same.  I also don’t see that RedHat CentOS8* releases include CentOS7 versions of libraries.

As an update I’ve tested another run (bert, 7.2.0, no flags, recon-all) on an OS-8 system but set LD_PRELOAD to the 7 system’s libm.so:
 
export LD_PRELOAD=/alma/cos7lib/libm.so
recon-all ….
 
And that produced the equivalent results of all my CentOS7 runs:

I believe this is very important information to the general community for stability with the imminent and inevitable switch to OS-8 HPC platforms.
 
Best,
