I can not get my workstation to run as fast as I expect for the cores frquency and memory it has?

My workstation with 32 cores runs much slower than a single core (same frequency) PC when I run a serial code with many iterations? With the large memory the workstation has I expect at least similar performance?

Okay. Now we know, what you observe and what you expect. We do not know, what you do. Which code do you run? What is "much slower"? Does the job suffers from a slow disk access?

What is your question?

Thank you Jan. Consider the code as just a set of nested loops with simple calculations. Not sure how to check slow disk access but I think this is probably the key. The PC has one hard disk so MATLAB and the code I run (and any data generated) are installed in same disk. For the workstation MATLAB and code are run once from the same hard disk and secondly from the two different hard disks which are installed. The PC runs the code in about 8 second while the workstation takes around 105 second for both runs. I am checking the types of the hard disks used in both. regards

Yes, it was communication with disk problems. Problem solved now with MATLAB installed in the faster disk along with code files. Thanks Jan. Regards.
