mprime for MenuetOS

Tanaselia · 2004-10-17, 09:03

Ever heard about MenuetOS? (http://www.menuetOS.org), a tiny OS written in ASM only. That's why, I think it will be faster than most Linux-es. I wrote an email to George Woltman, but he is not so optimistic about a future version of mprime for MenuteOS because, he said, I was the only one who request it.
So, try menuet, and if you like it and consider that it woth it, wrote to George and tell him about it.
Maybe, in future, if the demand will be considerable, we will have a mprime version for MenueOS.

Even of the OS could perform every operation in zero time, it would have only a small effect on the performance of Prime95, a few percent at most, because Prime95 doesn't use the OS for anything time-critical.

The area the OS could have the most direct effect is probably in the memory manager, by giving Prime95 nice contiguous blocks of memory, or using a non-standard tlb setup customised to Prime95's needs. None of this depends on the speed of the OS itself though.

One reason that a tiny OS might be useful for Prime95 is that it might use less memory than something like Linux and so allow Prime95 to run on very memory-limited machines. It probably isn't worth developing another version of Prime95 for such an OS though, since the machines would have to be pretty old to benefit. Even my P120 with 24MB can run mprime from Linux without a swap file, I think it might even be possible on a 16MB machine, though I haven't tried.

I ran Prime95 v14 and v15 on Windows 3.11 with a 80486 and 8 MB of memory...

Hmmm, but when I use Linux, on the same computer like WinXp, my Linux results are slighty better than exactly the same results on WinXp...

How much is slightly? I get a variation of 1-2% when running on the same machine and the same OS on the same day :-)

If it is much more than that it could be due to Windows using a different graphics mode than Linux, especially if you have onboard graphics.

I forgot to mention that the P120 runs from a bootdisk, no hard disk, so has to keep the whole operating system plus mprime plus save files etc. in a ram disk as well :-)

I bet you really love it if the power fails.

Or do you have a good UPS? That's one of the things I like about laptops --- good built-in UPS.

I don't run it from the bootdisk all the time, just for testing purposes. Normally it runs as a nfs client, but even then only in winter ;-). I don't have UPS, but everything seems to recover from a power cut without problem most of the time.

I'm sure it does, if you have your save files on a real disk. My concern was more for when you run it from a RAM disk. Unless your machine uses NVRAM, and very few do in my experience, a power cut would seem to lose you all your work.

not if u backed to the floppy disk. and im shure you could slap something togeather such as 2 floppy disks boot off one p95 on the other menuet os is very small and doesnt really need to be permantlay saved and rpime95 can be backed to os were looking at a point were the cost for slow factor machines is nill.
