Title: Using a bunch of cores on CHD verification?
Post by: john iv on 10 March 2024, 20:05

Hi Roman, is there a way to have cmpro use as many CPU cores as possible to run through its deep -verify check on a CHD scan?  I'd still like to finish off checking my collection (made it to the guitar freaks last time) but it seems to do one at a time and take a good amount of time.  I thought I saw an option for cores somewhere in my wanderings of your settings.  Thanks -

Cmpro simply runs chdman and does nothing by itself…..

Ah, too bad.  I thought it might have the ability to kick off X separate versions of the chdman.exe verify based on cores and collect the results.

well...yes, it could be that running multiple chdman instances gives a slight boost....but in old cmpro I don't think I will add it.
The new scanner runs multiple threads for scanning sets anyhow but currently it only reads chd headers and does not perform a deep chdman based verify check.
Didn't have much time in January/February to look at the new scanner though....but it's alive and kicking....

Thanks for the notes.  I just let it run over the rest of the CHDs normally and only found one decompression error on "MAME\ROMs\kof98um\kof98um_v1_00.chd".  Replaced it and things were fine.  Cheers -
