= Running low latency applications on {product-title}
|
|
|
|
{product-title} enables low latency processing for applications running on commercial off-the-shelf (COTS) hardware by using several technologies and specialized hardware devices:
|
|
|
|
Real-time kernel for RHCOS:: Ensures workloads are handled with a high degree of process determinism.
|
|
|
|
CPU isolation:: Avoids CPU scheduling delays and ensures CPU capacity is available consistently.
|
|
|
|
NUMA-aware topology management:: Aligns memory and huge pages with CPU and PCI devices to pin guaranteed container memory and huge pages to the non-uniform memory access (NUMA) node. Pod resources for all Quality of Service (QoS) classes stay on the same NUMA node. This decreases latency and improves performance of the node.
|
|
|
|
Huge pages memory management:: Using huge page sizes improves system performance by reducing the amount of system resources required to access page tables.
|
|
|
|
Precision timing synchronization using PTP:: Allows synchronization between nodes in the network with sub-microsecond accuracy.
