Multi-threaded support / large batch support
We are beginning a project which will require very large batches of greyscale TIFF images to be converted. I have used Nconvert in the past, but given the size of our batch (50,000+ images at a time), I didn't know if nconvert could handle it well. We plan on doing this on a pretty powerful workstation (one or two quad-core processors, 8 GB memory) hooked to a very fast RAID array. Can nconvert take advantage of the multi-core/multi-processors and available memory? This will be running a 64-bit version of Windows (probably Vista Biz)...the download page specifically says "Windows Xp 64". Does this mean Vista 64 is not yet supported?
Thanks,
Bryan

No currently nconvert doesn't support multi-core/processor, and can be run on vista 64

Pierre,
That is very generous of you to look at a special version. Thanks.
In my defense, everything is really going multi-core and 64-bit. You pretty much cannot buy a single-core computer anymore and most of the mid-range Dell's I looked at were quad-core. 4GB of RAM was the minimum Dell offered on most of these also...meaning Vista 64 was pretty much as common as the 32-bit version.
Thanks again,
Bryan

Re: Multi-threaded support / large batch support
Hi Pierre,
Did you get a chance to get nconvert to run multi thread and make use of more RAM?
We also have a big project that needs multi thread abilities, or if you can help out in how to get the most out of nconvert for this project: we have around 200,000 images and we want to use nconvert to generate small thumbs for them.
What do you suggest the best approach be?
Thanks for your time and help!!

Re: Multi-threaded support / large batch support
perhaps to launch more than 1 instance of nconvert??

Re: Multi-threaded support / large batch support
Thanks a lot for your response Pierre!
we already tried this approach, we ran 5 "parallel" command lines on batches of images, but for some reason after a few hours the scripts would return errors, as if the nconvert.exe is being locked by one of the commands and thus the others are failing to call it?
so to solve you think if i just create nconvert.exe, ncovnert1.exe , nconvert2.exe, nconvert3.exe ... and call each one on each command line, would that be the solution?

Re: Multi-threaded support / large batch support
Nope each instance runs on separate batch of files

So strange that you have a problem... No message?khaledhawari wrote:Nope each instance runs on separate batch of files
