I couldn't find any information via search to determine this via the Intel or HP website. Can you enable NUMA nodes on this? How can you tell the side of each node if so? Is it always best practice to enable and size VMs based on this if it's available or does that depend if you're running an application like SQL that makes use of this?
What does numactl --localalloc do? Does it bind program allocation to only the single node that numactl --localalloc was run on? Or does it ensure that whenever the program allocates its given memory from its local memory?
My boss wants to know if the HP DL320 G5 is NUMA enabled. I've tried scouring the internet, but can't find any specific information.
Does anyone know off hand if this server is suitable for running NUMA applications?
I am trying to install VMware ESXi onto a new dedicated server. However, when I boot from the VMware ESXi Installer CD, I am given the following error:
The system has found a problem on your machine and cannot continue.
The BIOS reports that NUMA node 1 has no memory. This problem is either caused by a bad BIOS or a very unbalanced distribution of memory modules.
How can I resolve this error? Here are the specs of the machine:
- Custom hardware assembled by my datacenter (I.E. not name brand like Dell, etc)
- AMD Quad Opteron(tm) Processor 6128 8-core (32 total cores)
- Supermicro H8QG6/H8QGi
- 24GB DDR3 RAM
- 4 physical CPUs
- Most likely 4x 6GB DIMMs, could be different.
Here's some more info I can obtain from the commandline:

I'm looking to buy a workstation for data processing using MATLAB. I'm considering one of two workstations from DELL. The lower end workstation (3500) has a single processor and 24 GB of memory in 6 DIMMs. The higher end (7500) will only allow me to select 24 GB of memory (in 12 DIMMs) if I select the dual-processor option. The difference between the two seems to be that
The Dell Precision T3500 has a three channel memory bus architecture.
The Dell Precision T7500 has a three channel memory bus architecture per processor
Does this mean that each processor gets 12 GB of memory, and a thread on processor A can't see the same memory as processor B? This seems unlikely, but maybe there is a performance penalty for A to access B's memory?
