[resolved] Optimized for Mac Pro?

Hello,

Peace and grace in our Lord!

We are considering upgrading our aging Mac and would like to know if the new Logos 6 is optimized for multicore performance on the most recent Mac Pro (late 2013 model). Currently, I use Logos on a Macbook Pro with a 2.3 GHz Core i7 and 16 GB RAM. It runs pretty well, but with large searches, there is some lag under pressure.

How will it run on the new Mac Pro? Anyone have any experience with this?

Thank you kindly

Currently I am running a 3 Windows computers, but from what I understand the hardware effects both the Windows and Mac version of Logos similarly. The number one factor for speedy searches is a SSD. When I upgraded my Windows computers to SDD the difference was like night and day. As for multi-core processors Logos only uses more than one core for indexing. However, most of us are not just running Logos so the multiple cores in the i5 or i7 found in a Mac Pro will help.

I am waiting for the Fall for my next computer upgrade. 1) Windows 10 is MS last chance as far as I am concern, so I would like to try it out first. If MS does not vastly improve Windows it is hello Mac! 2) There are strong indications that the next generation Sky Lake chips will be coming out this summer or fall. The 15 inch Mac Pro may not ever have Broadwell chips in them, it is rumored that Intel may just skip Broadwell entirely for desktops and performance laptops.

Thanks, Keith, for your help.

It's good to know that Logos does not use more than one core for most tasks so that I can focus more on I/O speed and perhaps RAM rather than raw processing power. Hopefully, the engineers will continue to improve the software so that it can tap into all of the power we find in today's computers, like the powerful GPUs that are being shipped in most high-end Macs, etc.

This isn't true.

Logos will use your additional processor cores for: searching, running Guides, updating the Information Panel, indexing your Notes and other documents, and literally hundreds of other background tasks.

Logos will use all the cores available to it in the system (if you're running multiple searches & guides simultaneously, for example).

Thanks for the clarification, Bradley.

I understand your response to mean that Logos will know the difference between a 4- and 6-core machine and utilize those extra cores efficiently. Is that correct?

Also, does Logos tap into the GPU for any processing?

That is correct, but it depends on the amount of work you're doing. If you're just opening resources from the Library, there may not be much for those extra cores to do. But if you're running multiple Guides or searches simultaneously, then they can be used.

Also, does Logos tap into the GPU for any processing?

The GPU is used for hardware-accelerated rendering in some areas of the program. (Given that Logos 6 isn't a bleeding-edge 3D game, and given the good performance of even low-end graphics cards these days, I'd guess it'd be unlikely that there would be noticeable differences between different GPUs.)

Thanks... that is a big help for us in making a decision about the next Mac.

When did this change take place. For years the answer was indexing only. I am glad to hear that Logos uses multi-cores for more now.

In Logos 4. It was built from the ground up to be multi-threaded.

For years the answer was indexing only.

I've posted about Logos 4's multithreaded design since 2010 or earlier, e.g., https://community.logos.com/forums/p/26614/196656.aspx#196656
