strategy tester extreme long duration

 

Hi,

I use a 40 core xeon cpu and 80GB mem, 3 SSD RAID striping set for cache and 48TB HDD, 2x10gBit network.

A test cycle in strategy tester with a single pass is 9 minutes. if I want to find optimized values I choose so, that it is a multiple of 40. So it does 40,80 or 200 cycles.

I believed, that 40 cycles are only a little bit longer (only admin) as 1 cycle because of parallelism.

I run 2x metatrader 5 under gentoo linux and wine with each 20 agents.

Problem: test duration is 5 hours+ for 200 cycles. But it should be 1 hour.

Do you have suggestions what can cause this issue?


many thanks

Al

 
How much physical cores do you have ? Metaquotes recommends to use ONLY physical cores, not hyper threading.

Very good hint. It is a Intel Xeon Gold 6138. It has 20 physical cpu's and 2 logical per physical. I will try it with only 20 agents.
