Plot dies with memory not mapped (segfault) (PR#9785)
Full_Name: Clay B
Version: 2.5.0 (2007-04-23)
OS: Solaris Nevada Build 55b
Submission from: (NULL) (65.101.229.198)
I find that running this script causes R to segfault reliably. However, running
just for one system at a time (modifying the for loop updating iter to run just
for a system at a time works). The system is a Sun W2100z with 12 GB of ram, and
R segfaults using only around 360 MB of

[PATCH 5/6] xen, tools: calculate nr_cpus via num_online_cpus
Once Xen calculates nr_nodes properly, all nr_cpu calculations based on
nr_nodes * sockets_per_node * cores_per_socket * threads_per_core are
broken. The easy fix is to replace those calculations with a new field,
nr_cpus in physinfo which is calculated by num_online_cpus(). This
patch does so and attempts to change all users over to nr_cpus field in
physinfo. This patch touches

R, OpenBLAS and OMP_NUM_THREEADS
What is the correct way to globally configure R to default to single (or
at least, << NUM_CPUS) threaded operation?
Using R 3.3.1 (both in debian unstable or using the CRAN repository for
xenial) with OpenBLAS (0.2.18) defaults to using one thread per
available CPU, which isn't ideal for machines more than a couple of CPUs.
Setting the environment (OMP_NUM_THREADS or

R, OpenBLAS and OMP_NUM_THREEADS
Hi,
Create /etc/profile.d/openblas.sh.
Write the following during in this file.
OPENBLAS_NUM_THREADS = 1
export OPENBLAS_NUM_THREADS
OPENBLAS_NUM_THREADS environment variable does not affect the OMP_NUM_THREADS.

[PATCH] nr_cpus calculation problem due to incorrect sockets_per_node
Testing on an 8-node 128-way NUMA machine has exposed a problem with
Xen''s nr_cpus calculation. In this case, since Xen cuts off recognized
CPUs at 32, the machine appears to have 16 CPUs on the first and second
nodes and none on the remaining nodes. Given this asymmetry, the
calculation of sockets_per_node (which is later used to calculate
nr_cpus) is incorrect:

[LLVMdev] Google Summer of Code
+Easily, some of the code snippets end up being copied dozens of
+times, which leads to worse maintainability, understandability and logical
+design.
The project description stresses code maintainability and logical design more than bug finding due to omissions in copy and pasted code. Reading this made me think of a check that would suggest people to replace copy and pasted code with a function

Puppet on busybox, Bob Hope or No Hope?
When I say busybox it''s actually VMware ESX server which seems to use
busybox (which I guess is the case a number of other software appliances) .
Reason for wanting to install puppet is to run the cli tools to create
nightly vmware snapshots.
I''m happy to give it a go (and add the docs to the wiki) but I''m not too
sure at this stage how big a task this might be and what,
