What is Rivet?

Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.

Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

What is Slurm?

Slurm coordinated a 7-CVE security drop across three active branches, including a privilege escalation and SQL injection.

Slurm released coordinated security patches across three active branches (25.05.x, 25.11.x, 26.05.x) fixing 7-8 CVEs per branch: sbcast credential bypass (CVE-2026-65107), slurmstepd stack overflow via SPANK environment variables (CVE-2026-65108), OCI container directory traversal (CVE-2026-65109), heap over-read in forward data RPC (CVE-2026-65138), SQL injection via cluster names in accounting queries (CVE-2026-65139), operator-to-administrator privilege escalation (CVE-2026-65140), and step distribution issues (CVE-2026-65165). The 26.05.3 patch also added support for external nodes in heterogeneous jobs — a meaningful expansion for cloud-burst HPC workflows.

7.5

Rivet 3.0 Preview runs as one stateless binary on WarpDrive, with S3 as its only dependency.

◆ Current state

Rivet has spent two months building infrastructure for long-lived actors and AI agents: BYOC in customer clouds, OpenTelemetry tracing, actor-scoped JWTs, Pi agent runtimes and agentOS Hosted VMs. On October 5 it said 3.0 would replace NATS with S3. The October 26 3.0 Preview delivers that: a new storage engine, WarpDrive, promises bottomless storage on S3 at SSD speed, and Rivet becomes a single stateless binary.

◆ Where it's heading

Each release removes operational burden: BYOC moved the control plane into the customer's cloud, and 3.0 reduces the self-hosted footprint to one binary plus an S3 bucket. The agent work (Pi, agentOS) sits on top as the main workload Rivet is courting.

◆ Prediction

Expect benchmarks and migration guidance for 2.x users during the preview, followed by a 3.0 GA. The entry gives no performance numbers, so the SSD-speed claim is unverified.

DEVOPS
5.0

Slurm coordinated a 7-CVE security drop across three active branches, including a privilege escalation and SQL injection.

◆ Current state

Slurm released coordinated security patches across three active branches (25.05.x, 25.11.x, 26.05.x) fixing 7-8 CVEs per branch: sbcast credential bypass (CVE-2026-65107), slurmstepd stack overflow via SPANK environment variables (CVE-2026-65108), OCI container directory traversal (CVE-2026-65109), heap over-read in forward data RPC (CVE-2026-65138), SQL injection via cluster names in accounting queries (CVE-2026-65139), operator-to-administrator privilege escalation (CVE-2026-65140), and step distribution issues (CVE-2026-65165). The 26.05.3 patch also added support for external nodes in heterogeneous jobs — a meaningful expansion for cloud-burst HPC workflows.

◆ Where it's heading

Slurm's three-branch maintenance model reflects the reality of HPC deployments: clusters running critical workloads don't upgrade quickly, so SchedMD backports security fixes to older release lines rather than forcing upgrades. The CVE density in this release cycle — particularly the accounting database SQL injection and the privilege escalation — suggests the accounting storage layer is under active security scrutiny. Feature work in 26.05.x continues on external node support and async step improvements.

◆ Prediction

The accounting database SQL injection (CVE-2026-65139) will likely prompt a broader audit of user-controlled inputs to the accounting storage layer. External hetjob support in 26.05.3 will expand as cloud-burst deployments become more common in AI/HPC workloads.
