Cpu known issues

Reconstructor - CPU known issues

Systems with multiple sockets:

NUMA is enforced by the hardware (each CPU socket is physically connected to a separate memory controller, and inter-CPU memory access is possible but highly penalized.
Not much can be done, other than set Rec affinity to a single NUMA node, and only use the cores that belong to said node (minimal changes to our multithreading core count detection are required).
Using multiple CPUs (multiple NUMA nodes) efficiently would require changes to the implementation of our algorithms, to be aware of that.

Systems with only one socket:

Certain somewhat recent Xeon CPUs allow the creation of virtual NUMA nodes (clusters of cores) within the same die.
In some cases this is purely virtual, and can be disabled at the BIOS level. In some other cases this is tied to the physical architecture of the die, and while it may be possible to disable it at the BIOS level, it might or might not yield benefits to Rec (this would need to be tested with one such computer, benchmarked under different configurations)

[1]. The system is below the recommended hardware requirements

This system is below the recommended hardware requirements.

The recommended CPU families are Intel Core i7, Intel Core i9, Intel Xeon.

[2]. The system is below the recommended hardware requirements

This system is below the recommended hardware requirements.

The recommended minimum amount of physical cores is 4.

[3]. Multi-CPU usage

Systems with multiple CPUs aren't supported by Reconstructor. In order to use the software with no performance penalty on such systems, the process affinity must be configured, so that it runs on all the cores of one single CPU. This will limit the amount of CPU cores and memory available to Reconstructor, but will allow multiple copies of the program to run on separate CPUs.

[4]. NUMA configuration

Systems that expose their CPU as multiple NUMA nodes aren't optimal for the heavy workloads Reconstructor is capable of. In order to run Reconstructor with no performance penalty caused by the memory partitioning, NUMA must be disabled on the computer's BIOS. Please contact your hardware manufacturer for details.

[5]. Cluster-on-die configuration

This family of CPUs offers the Cluster-on-Die functionality, that can split the CPU into multiple logical CPUs as clusters of cores, with separate RAM partitions. If this feature is enabled, the performance of applications requiring to share large memory allocation between multiple threads is negatively affected. In order to run Reconstructor without performance loss, it is recommended that the Cluster-on-Die functionality is disabled in the computer's BIOS. Please contact your hardware manufacturer for details.

[6]. Internal die topology

This family of CPUs provides several cores in the same package, with multiple memory controllers shared by them. Access to memory across different CPU cores might suffer increased latency in some cases, and has not been benchmarked. On CPUs that support the Cluster-on-Die functionality, this can likely be mitigated by disabling such functionality, but further tests may be necessary.
