GVT

GVT is an acronym that can refer to several terms across different fields, so its meaning depends on the context in which it is used. It is most commonly encountered in technology and medicine, but it is also used by various organizations and products.

In computing, Graphics Virtualization Technology (GVT) is a family of approaches developed to enable a single graphical processing unit to be shared among multiple virtual machines. Intel’s implementation, often discussed as GVT, includes variants such as GVT-d and GVT-g. GVT-d deals with direct device assignment to virtual machines, while GVT-g provides a virtualized, shared GPU resource model for guests. These technologies aim to improve virtualization performance and efficiency, particularly on systems with integrated GPUs, by balancing isolation, resource utilization, and workload flexibility.

In medicine, the graft-versus-tumor (GVT) effect describes the anti-tumor activity of donor immune cells after allogeneic hematopoietic stem cell transplantation. This immune-mediated destruction of residual tumor cells can contribute to cancer control but must be balanced against the risk of graft-versus-host disease. Understanding and leveraging GVT is a focus of research and clinical practice in transplant oncology, with strategies such as donor lymphocyte infusions and tailored immunosuppression used to optimize outcomes.

Beyond these domain-specific uses, GVT is also an acronym adopted by various organizations, events, or products. Because meanings can vary widely, identifying the precise interpretation of GVT requires context from the surrounding information. If you have a particular field or usage in mind, that context will point to the intended meaning.
