Hello.  GlobalBoost-Y just launched and it is a cpu only coin.  It uses the yescrypt algo, so their is no mining software yet.  It is the first coin to use this algo.   I wanted to reach out and see if we could get some assistance.  We can pay for the work.
If you already have a working C implementation of the algorithm (and it looks like you do) then it should be straightforward to fork cpuminer and add the algorithm to it, as has been done dozens of time already for other algorithms.
If what you are looking for is an optimized implementation of the algorithm, that's a different kettle of fish. Unfortunately I'm extremely busy with other projects, and have no time to work on this, not even as a paid job.

How do I change the api port? If I use --api-port=4002 the program says unknown option --api-port=4002. Is there a way to tell it to use another port?
cpuminer has no API. You must be confusing it with cgminer or with some fork of it.

Thanks for the info pooler.  We did get cpuminer and minerd working for yescrypt.  Below are the links.

Where can I download a binary that for linux that will use X11. I can't seem to compile it. A binary of 2.4 works great with scrypt but want to try X11.

Sorry, i cant find is this new question or not. But CPUminer runs smoothly on my virtual servers for 35 minutes, then crash down. I found when i use -t 3 or -t 4 it takes 35min to crash, when i dont use -t it can crash in minutes.

Any help?

You should not run cpuminer (or any other CPU-intensive application) on shared servers.

The -t is for how many threads or computer cores you want to use.  If you have a problem with overheating, use fewer threads.  Notice the difference between threads and cores.  Intel has hyperthreading, which means two THREADS per core.

Version 2.4.1

  • Added full support for scrypt(N, 1, 1) (e.g. --algo=scrypt:2048).
  • Added optimized PowerPC code for scrypt and SHA-256d. Both an AltiVec version and a plain PowerPC version have been included (compile with --maltivec or --mno-altivec to choose). The AltiVec implementation is currently optimized for the 74xx family (PowerPC G4). Observed performance: 2.06 kHps/GHz for scrypt, 987 kHps/GHz for SHA-256d.
  • It is now possible to use getblocktemplate with merge-mined cryptocurrencies.
  • The miner will now automatically switch to getwork from getblocktemplate if no payout address is provided.
  • Fixed a couple of security issues.

The source code is, as always, available at GitHub. Source tarball and binaries are available at Sourceforge.
