Great, thanks. Not a big jump at lower voltages, which is what I was hoping.

Michael, any data on Ivy/Sandy bridge temp or power increases?
14) Message boards : Number crunching : Haswell AVX2 version of LLR available (Message 75529)
Posted 3156 days ago by Profile Johnny RottenProject donor
I can't wait to see how the Haswell-E performs with the new LLR. 8 or 6 cores, with quad channel DDR4 2133 support. With fast memory and a good cooling solution, it should be very quick.

Patiently waiting... for Q2
15) Message boards : Number crunching : Proposed badge level adjustment (Message 75282)
Posted 3163 days ago by Profile Johnny RottenProject donor
After reading through the what Michael and others have posted so far, I am in agreement that a change is now due for these categories to bring them in alignment with the other badge awards.


I second that.

Definitely an app issue then, hopefully solved soon. With phones and other devices running faster than computers 3 yrs ago, is LLR possible on android if an app is created? (and android devices get a Huge cache upgrade via 64bit cpu's)

John


LLR is all double precision floating point, which a lot of ARM processors don't support at all, and if they do, they'll be much slower than modern desktop CPUs. AVX is a set of vector processing instructions that allow the CPU to do 4 floating point operations simultaneous.

That's why only the sieves are good candidates for Android, and the PPS Sieve is sized for GPUs. That leaves just the TRP sieve.



Good point, I forgot about that.

Thank you Michael for taking a look at this issue. My S4 spent many nights sleeping on an icepack for trp_sieve! (Although it didn't need it, with the thermal protection, the 4 cores ran at max on ice). It must be something with the validation process, just a guess though.

Please let me know if (and when) you find a factor (validated) with your Nexus.
I was running them on my S4 and Motorola Droid Bionic a while back until I saw the "validation inconclusive" message when I actually found a factor. I think TRP_Sieve for android is broken, or the validation process, and a waste of time personally. Had no response to my post earlier so it leads me to believe that it is compromised.

Good luck!

John

The 2 benefits of running LLR with Hyperthreading off,

1. Speed - Tasks complete faster

2. Heat - CPU runs cooler (air-cooled 3770k)
