How to reduce the CPU usage of CVX Mosek without affecting problem solving ？
When I use parfor for parallel computing, the Mosek solver consumes a lot of CPU and the CPU temperature is too high.
Will setting parameter ‘MSK_IPAR_NUM_THREADS’ affect problem solving？
By default MOSEK will automatically select the number of threads.
However, the maximum number of threads allowed can be changed by setting the parameter ‘MSK_IPAR_NUM_THREADS’ and related parameters. This should never exceed the number of cores.
(link: 9 Technical guidelines — MOSEK Rmosek package 10.2.6)
Thank you! I have tried it. This method reduces CPU utilization to a certain extent.
The CPU utilization is too high, and the CPU temperature will also be very high. I am worried that it may damage the CPU.
Based on your suggestion, I also learned about the method of setting the number of MOSEK threads from the link ( 9 Technical guidelines — MOSEK Rmosek package 10.2.6).
Due to the need for a large number of for-loops in my code, I used parfor for acceleration. In order to prevent CPU utilization and high CPU temperature, I only used a small number of CPU computing cores.
When I use MSK_IPAR_NUM_THREADS = 1, the following prompt ‘NOTE: custom settings have been set for this solver.’ appears in the command line window. Can this prompt be canceled?
