VCAC-A R6 release

• Upgrade OpenVINO to 2020.4 release
• V2X pipeline is enabled/integrated to Open Visual Cloud Smart City
• VCAC-A kernel upgrade to kernel-5.3.18

Fixed Bugs

• GPU plugin (IE CLDNN) memory consumption increased since 2019 R2 release.
• VCAC-A autoboot solution does not work properly with NetworkManager enabled.
• Error during command: “vcactl temp”
• VCAC-A BIOS has old uCode (at least L1TF is not mitigated)

Known bugs and limitations

• Switching Plugin from HDDL to MYRAID shows error. OpenVINO design does not support switching between the hddldaemon and Myraid X plugins. (VMPI-41)
• vgg16 could not run with density 24 due to a VCAC-A DDR memory size limitation. (VMPI-139)
• Performance regression with OpenVINO 2020.4 when using HDDL bypass mode. (CVS-33917)
• ntel® model vehicle-license-plate-detection-barrier-0106 does not support dynamic batch size. (CVS-34044)
• GPU VCS0 hangs when running Media Analytics pipeline repeatedly.(VCD-1654)
• VCA configuration file is broken after non-graceful system shutdown (power switch restarts). (VCASS-2578)
• Sometimes the vcactl os-shutdown command fails.(VCASS-3071)
• The vca_config_upgrade.sh script does not recover removed option in manual mode.(VCASS-27)
• Confusing message in vca_config_upgrade.sh script.(VCASS-152)

VCAC-A R5 release

• Upgrade OpenVINO to 2020.2 release
• Add VPU metric support telemetry for K8s and OpenNESS , which exports VPU utilization, thermal and memory usage data
• Support HKH SW stack deployment via KVM VM on Xeon host

Fixed Bugs

• Multi-device inference when batchsize>1 with some models failed for Const layer reshape error
• Memory leak in inference engine mkldnn(tbb) and cldnn(Core::LoadNetwork)
• Error: ncFifoDelete() failed occurs while running stress test to start and stop Analytic pipeline on VCAC-A
• GPU inference does not work with Openpose Models
