AMD Ryzen and CentOS
I have a new system with an AMD Ryzen 1600 CPU and I'm trying to run
CentOS, so far without success. The only information I could find was
a post reporting that CentOS 7 would crash during installation on a
Ryzen system: https://www.centos.org/forums/viewtopic.php?t=61831 .
I tried updating to the latest elrepo "mainline stable" kernel,
version 4.11 (by booting from a live CD and

The issue is likely about the chipset not being properly supported and so you will have to wait and see if 6.10/7.4 helps. You may want to check the RH release notes for RHEL 6.10/7.4 and see if support for the processor is listed there.
While I can't assure you that upgrading to 7 will fix the problem, the likeliness that will work is at least 50% better being as 7 is based on a newer

parallel PSOCK connection latency is greater on Linux?
I'm exploring latency overhead of parallel PSOCK workers and noticed
that serializing/unserializing data back to the main R session is
significantly slower on Linux than it is on Windows/MacOS with similar
hardware. Is there a reason for this difference and is there a way to
avoid the apparent additional Linux overhead?
I attempted to isolate the behavior with a test that simply returns

parallel PSOCK connection latency is greater on Linux?
Could TCP_NODELAY and TCP_QUICKACK be exposed to the R user so that
they might determine what is best for their potentially latency- or
throughput-sensitive application?
Best,

How many network packets are generated with and without it? If there
are many small writes and thus setting TCP_NODELAY causes many small
packets to be sent, it might make more sense to set TCP_QUICKACK
instead.

I've installed CentOS 7 with the latest kernel from elrepo (4.11.8),
and I can't get Grub to install. I think I'll have to conclude that it

hardware issues and new server advice
hi,
our current servers are suffering from a weird hardware issue that
forces us to start over.
in short we have two servers with 15 disks at 6TB each, divided into
three raid5 arrays for three bricks per server at 22TB per brick.
each brick on one server is replicated to a brick on the second server.
the hardware issue is that somewhere in the backplane random I/O errors
happen when the system

parallel PSOCK connection latency is greater on Linux?
Please, check a tcpdump session on localhost while running the following script:
library(parallel)
library(tictoc)
cl <- makeCluster(1)
Sys.sleep(1)
for (i in 1:10) {
tic()
x <- clusterEvalQ(cl, iris)
toc()
}
The initialization phase comprises 7 packets. Then, the 1-second sleep
will help you see where the evaluation starts. Each clusterEvalQ
generates 6 packets:

I'm not sure the user would know ;). This is very system-specific issue just because the Linux network stack behaves so differently from other OSes (for purely historical reasons). That makes it hard to abstract as a "feature" for the R sockets that are supposed to be platform-independent. At least TCP_NODELAY is actually part of POSIX so it is on better footing, and disabling

Zen arch in 5.0?
Will 5.0 have scheduler, reg alloc etc. bits for explicit
support of AMD's 1st gen Zen (Ryzen, Epyc) arch?
Is it safe to assume that the changes for Zen's 2nd gen
will land prior to the hardware release, once the 1st
gen is added? I think zen2 will arrive next year.

AMD IOMMU + SME + amdgpu regression
Hi,
amdgpu + IOMMU + SME is now working for me on 5.7, yay! But, it is
broken on torvalds master, boo. On boot, depending on which exact commit
I test, it either hangs immediately (with built-in driver, before
starting initramfs), displays some errors then hangs, or spams the
screen with many amdgpu errors.
I bisected the black screen hang to:
commit dce8d6964ebdb333383bacf5e7ab8c27df151218

WoW WOTLK => Patch 3.3.2 kills my fps....
After upgrading to a Club 3D Radeon 5770 overclocked edition i was finally able to get some good fps out of wow... 90 => 110 FPS in Stanglethorn Vale with all the graphics option to their lowest setting possible.
However last night the game installed patch 3.3.0 => 3.3.2....

Motherboard for home zfs/solaris file server
Hello,
I am building a home file server and am looking for an ATX mother board
that will be supported well with OpenSolaris (onboard SATA controller,
network, graphics if any, audio, etc). I decided to go for Intel based
boards (socket LGA 775) since it seems like power management is better
supported with Intel processors and power efficiency is an important
factor. After reading several
