Hi John,

First of all, "Merry Xmas"!

I've a little problem compiling your code on my laptop:

Could you help me, please? Thanks, Marco

Happy holidays, Marco!

I've a little problem compiling your code on my laptop:

time ./mean30sx8 -n 63 Looking for 42-cycle on cuckoo30("",63) with 50% edges Using 3168MB bucket memory at 7fc335202010, 1x21MB thread memory at 7fc333d11010, 8-way siphash, and 128 buckets. nonce 63 0.12user 2.36system 0:23.55elapsed 10%CPU (0avgtext+0avgdata 3268776maxresident)k 16inputs+0outputs (0major+816560minor)pagefaults 0swaps make: *** [Makefile:105: demo30x8] Error 4

This looks like an execution problem rather than a compilation problem. Did you perhaps run out of memory? You'd need to have at least 3200MB memory freely available...

You can also try running ./mean28x8, which needs only 800MB.

Hi John, my laptop has 16GB RAM and this is the output of free command:

$ free total used free shared buff/cache available Mem: 16324572 3241124 4887944 329360 8195504 12286772 Swap: 8191996 1804 8190192

Running mean28x8 I have the following error:

$ ./mean28x8 Looking for 42-cycle on cuckoo28("",0) with 50% edges Using 536MB bucket memory at 7fd87ad88010, 1x10MB thread memory at 7fd87a30f010, 8-way siphash, and 64 buckets. nonce 0 Illegal instruction (core dumped)

dear Marco,

my laptop has 16GB RAM and this is the output of free command:

Illegal instruction (core dumped)

Oh, in that case you have an older CPU with no avx2 support. So you cannot run the x8 executables. Try the x1 versions, e.g. make demo30x1

ok thanks. I wrote you an email regarding a project that I'm developing. Regards, Marco
