Vida CEM swapping

[vtl]

Also '++i' doesn't need to make a copy of 'i' first like 'i++' does.

Integer variable is not an object, C does not do copies.

Code: Select all

Mine...
    if ((n & 1) ^ ((k >> i) & 1))

That 'i' should be 1.

How do you get ~860 pin/sec? I am getting stable 440 pins/sec using VTL's the most recent build.

There are "fast" and "slow" CEMs. You have a "slow" one.

I could also not compile VTL's seed-gen.c utility. I was trying to compile with devc++ and with VScode as well. It could not find dependencies.

haha, i thought the same. I could run the Virtual Machine. Sounds like a plan.

I've heard that in recent windows versions they've added Linux shell or something, based on Ubuntu. You may want to try compiling it there.

I am kinda conservative Windows user running multiple Win7 laptops. I have Ubuntu experience also,
Thanks, vtl !

Why 1? For the 64 bit seed/pin combo I want the bit to match the for loop, so that's why it's set as i and not 1. I'm not checking the same bit each time through the loop.

I've created a virtual machine, installed Ubuntu there. After installing gcc, the code compiled like a charm. Now i need to understand how to use it

 * $ gcc -Ofast -o seed-gen seed-gen.c

pps is pins per second for your CEM.
