HIVE pivoted into the AI cloud market in 2022 when they acquired a 50MW facility in New Brunswick, Canada from GPU Atlantic, aka gpu.one.

It was almost impressive. Here is a list: * initially, no control plane machine * initially, no NFS mount, and then user’s default workdir was not on the shared filesystem * initially, no passwordless ssh between nodes * docker and the nvidia container toolkit not installed on the worker nodes * modules not installed, also no hpcx, nccl, nvcc * no pyxis or enroot * dcgmi background health checks not installed, or enabled * no prolog or epilog configured, no active health checks * no montoring dashboard To get around all of this, we ran a 2-node nccl test with the pytorch-bundled libnccl. Unfortunately, we did not see expected bandwidth (we about 10x lower than expected). This was weird, because ibstat showed 8x 400Gb CX-7 in the nodes. So, we quickly confirmed that both GPUDirect RDMA was not installed, and ACS was not turned off.

They’ve also committed to building our feedback into their default slurm offering going forward. However, even after these fixes, the cluster does not meet the standards we expect for usability, monitoring and health checks. It seems that BuzzHPC’s platform is still actively in development. We look forward to seeing more from BuzzHPC in the future. --- Other Bronze tier providers: - GMI: https://www.clustermax.ai/cloudreview/gmi - STN: https://www.clustermax.ai/cloudreview/stn - Prime Intellect: https://www.clustermax.ai/cloudreview/primeintellect - Neysa: https://www.clustermax.ai/cloudreview/neysa - Hyperstack/NexGen: https://www.clustermax.ai/cloudreview/hyperstacknexgen - Atlas Cloud: https://www.clustermax.ai/cloudreview/atlascloud - Shadeform: https://www.clustermax.ai/cloudreview/shadeform - Runpod: https://www.clustermax.ai/cloudreview/runpod - Verda/DataCrunch: https://www.clustermax.ai/cloudreview/verdadatacrunch - Digital Ocean: https://www.clustermax.ai/cloudreview/digitalocean - IBM Cloud: https://www.clustermax.ai/cloudreview/ibmcloud - Hot Aisle: https://www.clustermax.ai/cloudreview/hotaisle - Vast.ai: https://www.clustermax.ai/cloudreview/vastai - CUDO Compute: https://www.clustermax.ai/cloudreview/cudocompute - Lightning.ai: https://www.clustermax.ai/cloudreview/lightningai - Qubrid: https://www.clustermax.ai/cloudreview/qubrid - Latitude.sh: https://www.clustermax.ai/cloudreview/latitudesh - Denvr Dataworks: https://www.clustermax.ai/cloudreview/denvrdataworks Full ClusterMAX 2.0 + 2.1 index: https://www.clustermax.ai/cloudreview Full LLM dump of all reviews: https://www.clustermax.ai/llms-full.txt
