Dear Joseph,
Thanks for using MSNoise.
If there is only one core running it means probably that you have only 1
day of data to correlate. The multi-thread/processing of MSNoise works
based on "day" jobs, which are independent from the other days. With 1
day of data for N stations, you'll have N (N-1)/2 jobs "T"odo in the
database, but they will all be processed by the same thread.
Best regards,
Thomas

Dear Thomas,
I am using MSNoise to process a 250 Hz sample rate data set with
131 stations. I was trying to run my cross-correlations (compute-cc)
in parallel to make the computations faster. However, inspite of using
msnoise -t 14 compute-cc on a 70 cpu computer (256 Gb ram), the
cross-correlations still run on one cpu. The parallel instances of
'compute-cc' start and finish without doing any jobs. Is it because
the first instance sets all the jobs as 'I' meaning in progress, or
should I change something in my config to make it run in parallel. I
would appreciate your input about this problem. Please let me know if
you require any additional information.
Have a good week ahead!
