Thanks Matthew

Would love to run some very high number loop math problems on a nice performance machine. Besides, what is the use of having a 64 bit machine running at 32 bits.

I have been nothing but impressed with J on my htc smartphone as well as J on my pocket pc's. Have never been disappointed by the performance.

"what is the use of having a 64 bit machine running at 32 bits."

Whatever use you can get out of running a 32 bit program on a 32 bit
machine, you can get the same use out of running a 32 bit program on a 64
bit machine.


"some very high number loop"
Do you mean you want to have a loop such as below?

for_n. i. 2^33 do.
end.

Can you post some of your code which requires 64 bits?

dear Matthew,

the idea is to see what a 64 bit machine can do running 64 bit programs, (and the next step will be 128 bit machine running 128 bit programs one presumes). Then dual quads, lots and lots of fast GB RAM: progress.

good benchmarks would be the Euler-Mascheroni series, or the old series of 1/x^1.001, and such, the awfully slow converging things, a test of language, programmer, and machine.

aside from that, people set records for number of digits, and they always have since before Euler and Mascheroni's time, and they always will.

thanks

dick

Oh I see. You don't have a specific problem to solve. You are trying to test
the limits of technology. In that case, your task will never be complete
because your objective is to find problems to solve that you cannot
currently solve. If you had 64 bits then you would soon be asking for 128
bits, and so on.

I share your frustration on the lack of 64-bit J for OSX, I am using large
files which require 64 bit address space. I am not sure why it is a problem
to make it, but I don't know much about compilers etc... it probably
involves a lot of extra work and the 64 bit OSX demand is probably pretty
low (2 of us?!). Besides, I am happy running it on Ubuntu so don't think I
would use it even if it was released ... so that makes just one of you :-).

Why not buy a 64 bit Windows machine and have done with it?
