Do you happen to know if these apps will work on a FreeBSD machine? I have a 44 thread Xeon e5 v4 which definitely has AVX2
I think this is fool-proof but could you just try it for me please? • There are 10 types of people in the world; those who understand binary, and those who don’t

Looks like it does - there is an ABI in place for Linux compatibility for other projects. I will report once I get some validated WU

Theoretically it should be. However, if the 2690 downclocks when running AVX then the SSE3 might actually be faster.

2264 secs on average for first 20 WU with AVX. None have yet validated

Fairly hot for a Xeon but can't say I've ever checked it when running WCG. The temperature difference between the two CPUs is quite normal in a Dell as the exhaust from first CPU fan is intake for the second

Code: Select all

Package id 0:  +73.0°C  (high = +81.0°C, crit = +95.0°C)
Core 0:        +70.0°C  (high = +81.0°C, crit = +95.0°C)
Core 1:        +69.0°C  (high = +81.0°C, crit = +95.0°C)
Core 2:        +71.0°C  (high = +81.0°C, crit = +95.0°C)
Core 3:        +71.0°C  (high = +81.0°C, crit = +95.0°C)
Core 4:        +73.0°C  (high = +81.0°C, crit = +95.0°C)
Core 8:        +69.0°C  (high = +81.0°C, crit = +95.0°C)
Core 9:        +70.0°C  (high = +81.0°C, crit = +95.0°C)

The V3 and V4s have AVX2 and they down clock when running AVX2 due to the temperature rise. The V3s have a bug that causes all cores to down clock if any of them are on AVX2. The V4s will only down clock the cores that are running AVX2.
