[mesa-users] gfortan multithreading problems with mesa

[Bill P. <pa...@ki...>]

Hi,

I've just noticed something suggesting a multithreading issue with mesa when compiled with gfortran.
It is undoubtedly a bug on my part, but I haven't tracked it down yet.   It might be behind some 
ot the installation problems we've been having.

Basically, when compiled with gfortran (but not with ifort) I can quickly cause a convergence failure in a mesa star 
at any time during a run simply by starting up another run simultaneously in another terminal.   However, if I change
to a single thread, they don't interact and don't run into trouble.

I'll look into this, but in the meantime, you might try setting OMP_NUM_THREADS to 1 and see if the install goes better.
