The option "-th 0" will automatically fix a number of threads corresponding to the number of cores in your system.<br>

<div dir="ltr">Dear CASToR users
<div>I used castor_v2.1 and I exported CASTOR_OMP=1 and CASTOR_MPI for installation but when I run a program only one thread is used. I attached a picture that indicates it. How can I use multithreading for reconstruction? I used a big scanner and I need to
faster reconstruction!!</div>
<div>
<div>Any answer will be highly appreciated!<br>
