Question

Hardware influence on performance, multithreading, multicore - Mathcad Prime 9

Does anyone know what the internal processing limitations of MCP are w/ regards to the max processing speed and the number of cores, etc.? Same question for multithreading turned on and off.

 

My company recently purchased a 16-core, 3.2GHz/5.0GHz 'power computer' and I would like to know how much MCP can take advantage of this machine.

Thank you!

Hi,

I run a 16 core (32 logical processes) 3.4 GHz AMD Ryzen 9 chipset with Prime 9.  For video and sound processing it blitzes.

On Prime 8 Windows 11 Pro the Intel math kernel would not work for Cholesky, QR, eigenvecs, eigenval etc that use the kernel because of the AMD chipset.  Prime 8 would simply crash.

This is fixed in Prime 9 Windows 11 Pro. 

 

Some things like text processing can take a long time in Prime.  28 minutes in one case when compared to same algorithm routine in C++ that for the same text processing takes the blink of an eye.

 

The only way to time a worksheet using the time() function needs the multithreading off. So who knows?

 

I can't remember what the post was about but some timings with multithreading off were timed and my system was much faster.

 

Cheers

Terry

    Thank you @terryhendicott.
    Good to know that Prime 9 has fixed some of those issues.
    I will have to do some tests on my end to see how the hardware performs.

    Hi,

    In Prime one of the calculation options is to allow or not allow Prime to take advantage of multithreading

      @terryhendicott 

      It looks to me that you are answering to a bot.

       

      EDIT:

      Just if someone wonders what I am talking about:

      The offending posting Terry answered to was deleted by a moderator in the meantime so it now looks that he answered to the OP. IMHO the mod should have also deleted the two follow up postings from Terry and me.
