In our lab we have 2 x HP z800 workstations. It is somehow ridiculous piece of hardware in terms of today standards. It’s got over 1 kW power supply, dual CPU motherboard and 12 memory slots. It is loud, draws loads of power and it’s got comparable gen 1 Intel CPUs as well as DDR3 – slow – memory. However it costs close to nothing and it is suitable for most small and mid applications. Official documentation says that the maximum memory capacity is 192GB of DDR3, which is 12 x 16 GB sticks working at 800 MHz. If we
I’ve been playing around with several devices in a context of running OpenCL code on them. They have one common thing which is excessive heat coming out of GPU and heatsink being unable to dissipate it. I start with MacBookPro3,1. It has NVIDIA 8600M GT, which is known to fail. I assume that it may be linked with overheating. Second example is design failure of Lenovo Thinkpad T420s which has built in NVIDIA NVS 4200M. This laptop has Optimus feature which in theory could detect if workload should be run on discrete or integrated GPU. Unfortunately enabling either Optimus or
