I understand that. It kills my GPU mining when I use all cores. But I think you missed something in my post. I'm getting 5k PPS on 7 cores in the windows client but only 1k PPS in the Linux one.
Look up the "nice" command. Any CPU mining, whether built in to a coin or using minerd aka cpuminer or whatever, use "nice coind" or "nice minerd", it runs at lower priority so does not seem to impact GPU mining nor FPGA mining nor ASIC mining yet still gets to use most of the cores most of the time. -MarkM- I fixed my PPS in linux by restarting the linux VM. Now I'm looking into this "nice" command which is difficult to google by the way. I set: sudo nice -n -20 primecoind setgenerate true -1 And I'm still taking a 200khps hit on my GPU mining. It did improve by 50khps over the old way.

The client seems to crash for me after few minutes of mining running hp3-win64 on Win 7 x64 I7 930 ![](https://ip.bitcointalk.org/?u=http%3A%2F%2Fi42.tinypic.com%2F2cpdu9v.png&t=665&c=aYQofZtQ2bEGcw) any ideas?

I still only get about 1200PPS in linux vm but I'm getting 6000 in Windows. I was chitchatting with someone else and he said his Linux PPS got halved when he switched to this client too. Which Linux distribution are you using? I suspect some distributions might not be supplying a properly optimized version of GMP. I may eventually start releasing my own Linux binaries.

Maybe you should look into the "man" command first. But that's probably difficult to google as well. ![Roll Eyes](https://bitcointalk.org/Smileys/default/rolleyes.gif)

Ubuntu 12.04 Looks like Ubuntu 12.04 comes with GMP version 5.0.2. That's from Aug 2011. It may fail to recognize newer CPUs. In that case, it won't choose the optimal code path.

Is there a) A primecoin-qt app for Android. Or at least something that can show when a block is mined via an application? b) A PrimeCoin wallet app for Android yet?

New version is out!
-hp4 mainly adds L1 and L2 cache optimizations. It removes the performance bottleneck with bigger sieve sizes. Thus it's possible to increase sieve size even further.
I also added a new alternative performance measurement. The client now calculates the number of probable prime chains of length 5 and prints them to debug.log. The printing frequency is also increased.

I'm a bit confused.
The primes we are finding are huge, what purpose does the up-to-2,000,000 or so prime sieve serve?
Seconded. I'm guessing it's because the primality test used here is not absolute, it only tests for probable primality. One way to do this is trial division by smaller primes.

I've had two crashes using this high performance miner. ![Shocked](https://bitcointalk.org/Smileys/default/shocked.gif) The crash states: Assertion failed!
Program: C:\Users\xxx xxx\xxx\xxx\primecoin-qt.exe File: src/checkqueue.h, Line 167
Expression: pqueue->nTotal==pqueue->nIdle
Anyone else had this error/crash? On another note, I'm about ready to give up on Primecoin...I started at the beginning and mined 9 blocks the first day using 3 machines. Then mined 6 the next day, 3 the day after that, 1 more the next day, but I haven't mined a single block since even with the 3 CPUs running 24/7. ![Cry](https://bitcointalk.org/Smileys/default/cry.gif)

Is there a consensus on the best VPS provider yet? I'm averaging 180k PPS on 30 8-cores via DigitalOcean. I know there are other VPS providers out there, but anything as convenient as them? I can deploy an entire cluster in under 20 minutes from scratch and destroy them all in under 5.

Digital Ocean is very good with the low-tier instance. I have 40 instance 2-core. The solo-core is better but with limited droplet you have to make a choice.

I think I had it updated already. Then I tried removing it and reinstalled it, still no go. It wasn't till I restarted the vm client that my pps numbers came to be what it should've been.

Did you request more droplet from them?
