Hi John,

I recollect it being said that you could go higher, but never achieved it. My Win 3.1 PC went up to 1024x768 on a £500 Sony monitor.

Wilfried, Yes, multicore CPUs WORK in parallel wery nicely. Look at multithreading example in FTN95 release.

I also posted here simplified to the extreme version of this example a while ago, make a search for it, so now even your dog can do parallelization.

Hmm... Dan, I found a thread from you concerning parallel processing (click), but I didn't found useful code there (?). In one of your postings you mentioned commands like %em (???) or %we ("write in exponential form"; ???). May be I found the wrong thread.

In the moment I think that parallel processing is a bit more complicated (hope that I'll be wrong). Of course the operating system spreads different programmes to different processors if present, but parallelsation of a single programme is in the responsibility of the developer.

I made first tests with call_pprocess@ which seems to give good results. Of course there remains some work for a good logistic between the single threads. What I'm missing are commands to spread the work to several processors from within a single programme (exe file). Nevertheless, even if it will be necessary to subdivide my software into several executables, I will use parallelisation as soon as possible. In my work I deal with image processing and up to now in some subroutines I offer a "batch" mode saying that image per image will be processed one after another. I think that these are places where parallelisation will give a significant increase of speed.

Have a nice weekend,
Wilfried

Thanks a lot, Dan. OK, this week I will implement your ideas.

It's not my ideas.
It's my attemt of advertisement of capabilities of FTN95.
Which is kind of fixing of lack of company's own advertisement.
Which in its turn is done in kind of UK way.
Which seems is even worse then one of French way.
Which, finally, is not advertising anything at all Smile

just kidding

But a bit more seriosly, in my 30 years scientific life in physics I only knew 2 people (and 90-95% of them programmed in fortran at some point) who have HEARD about FTN77/95 not from me Smile

In my memory only DEC ever advertized this way (their VAXes, which were on sale like hot dogs, soooo.... may be they are eventually right)
