Dear developers,
I used yambo-4.1.1 setting the parameters as
X_all_q_CPU= "1 1 25 1" # [PARALLEL] CPUs for each role
X_all_q_ROLEs= "q k c v" # [PARALLEL] CPUs roles (q,k,c,v)
X_all_q_nCPU_LinAlg_INV= 1 # [PARALLEL] CPUs for Linear Algebra
SE_CPU= "1 1 25" # [PARALLEL] CPUs for each role
SE_ROLEs= "q qp b" # [PARALLEL] CPUs roles (q,qp,b)

In the log file, from log_3 to log_25, there are a warning like: [WARNING] Empty workload for CPU 3. But in log_1 and log_2, there is not such a warning. Does this affect the results? What the reason could be?

Thanks in advance!

Dear Shudong,

it should not affect the results, simply the calculation could be non efficient.
In order to understand what is happening we should look at the log/report files and see in which part of the calculation this happens.
I do not know the settings of your system anyway you can try to distribute the cpus among the other roles,
something like
X_all_q_CPU= "1 1 12 2"
SE_CPU= "1 2 12"

Best,
