Also - I read in a couple of places online that if you have OpenCL support
enabled then the CPU threading stops.
I can't test that to see if it is true because I can't seem to get OpenCL
to work on this Linux desktop.
Trying it on a Windows machine should answer that question.

To follow up on that.
Using LO 6.4 & 7.0 pre-release build on Ubuntu. Recalculating one of the
OpenCL test xls files just now.
Starting up with a command line
MAX_CONCURRENCY=0 ./soffice
Does turn the CPU threading off.
Restarting with a command line
MAX_CONCURRENCY=4 ./soffice
Turns it back on
BTW I'm copying a paragraph from an email on a different list.
"Also - if you set MAX_CONCURRENCY=16 - or somesuch (ie. twice your
number of threads) - you may be able to defeat the hyper-threaded
halving, and see if this workload happens to be one that does better
with hyper-threading than withou
Mike and Luboš,
Many thanks for your help on this topic.

Hi Luboš,
Many thanks for your thoughts on the checkbox, which confirms what I
expected.
As for the processing itself, I remain unclear about how Calc allocates
tasks to threads. Can we give the user any general advice on how he could
structure his spreadsheet to gain the maximum performance bene

Hi Developers
