Is LO Calc capable for SMP?

Hi,

Q:
I wish to learn : is LO designed to exploit a multi-core (i7) processor environment ?
or it runs by design on single processor core only ???
(although there are 7 more available)

P:
During daily work, I am manipulating large spreadsheets, w/ lot of vlookup’s and other similar functions.
It slows down the laptop for a long duration.
I have monitored w/ System monitor :

  • one single core (out of 8) is loaded almost 100%,
  • the rest just a few percents
  • swap memory bank ( 4GB ) is exploited by nearly 100%

The comparison w/ MS Office Excell, on same data, same machine, same file format shows :

  • parallel exploitation of 8 processor core-s
  • faster run ( fraction of the LO )

The (wished to) work environment :

  • Lenovo T520
  • Ubuntu 12.04, 64bit
  • LO 3.6.

Thnx in advance
Gyorgy

AFAIK (i’m not a LO developer): No, it isn’t capable to use more than one CPU core. See this overview over multi-threading development - seems to be stalled since 2009 :expressionless:
Here are some OOo forum threads on this:

Thanks a lot for the answer. Is an unpleasant content, but at least is fairly clarifying the status. I’ll try to suggest the development somehow via LO bug-reporting interface.
