HTCondor is a software system that creates a High-Throughput Computing (HTC) environment. It
effectively uses the computing power of machines connected over a network, be they a single
cluster, a set of clusters on a campus, cloud resources either standalone or temporarily
joined to a local cluster, or international grids. Power comes from the ability to effectively
harness shared resources with distributed ownership.
Learn More About HTCondor
The HTCondor-CE software is a
Compute Entrypoint
(CE) based on
HTCondor
for sites
that are part of a larger computing grid
(e.g.
European Grid Infrastructure
Open Science Grid
).
As such, HTCondor-CE serves as a "door" for incoming resource allocation requests (RARs) — it handles authorization and
delegation of these requests to a grid site's local batch system.
Supported batch systems include
Grid Engine
HTCondor
LSF
PBS Pro
Torque
and
Slurm

OSPool and Its Computing Capacity Helps Researchers Design New Proteins
December 15, 2025
Where to find freely available GPU and CPU computing resources for research on diseases like Alzheimers, Parkinsons, and ALS? This challenge faced by labs and researchers is becoming more acute with the increasing use of AI and machine learning (ML) which demand more computing capacity. For Dr. Priyanka Joshi’s [Biomolecular Homeostasis and Resilience Lab](https://www.joshilab.org/) at Georgetown University, the National Science Foundation (NSF) supported [OSPool](https://osg-htc.org/services/ospool/) and its [HTCondor Software Suite](https://htcondor.org/) was the answer.
