Utilizing memory coherency to improve bandwidth performance

Abstract:

A computer implemented method uses memory coherence to enhance latency and bandwidth performance, the method including receiving, by a host, a call from an application. The method also includes, determining that the call includes a device allocation command, wherein the device allocation command is configured to allocate a set of data on a graphical processing unit. The method further includes intercepting the call. The method includes, initiating an alternate data allocation command; and returning the alternate data allocation command to the application. Further aspects of the present disclosure are directed to systems and computer program products containing functionality consistent with the method described above.
