Systems and methods of allocating GPU memory

A non-transitory computer-readable storage medium storing one or more programs for execution by a server system executing a third-party application, the server system in communication with a client device, the one or more programs including instructions for:

• initializing, for the third-party application, an entirety of available GPU memory of the client device, including pre-allocating a plurality of blocks of GPU memory;
• during execution of the third-party application:
• receiving a first request from the third-party application to store first data in the GPU memory of the client device;
• in response to the first request:
• freeing a portion of a respective pre-allocated block of the plurality of pre-allocated blocks of GPU memory;
• storing the first data in the portion of the respective pre-allocated block;
• and
• pre-allocating a new block of GPU memory of the client device, the new block comprising a complementary portion of the respective pre-allocated block such that, after pre-allocating the new block of GPU memory, the entirety of available GPU memory of the client device remains allocated.

A server system hosting a virtual machine executing a third-party application, the server system in communication with a physical client device, comprising:

• one or more processors;
• and
• memory storing one or more programs for execution by the one or more processors, the one or more programs including instructions for:
• initializing, for the third-party application, an entirety of available GPU memory of the client device, including pre-allocating a plurality of blocks of GPU memory;
• during execution of the third-party application:
• receiving a first request from the third-party application to store first data in the GPU memory of the client device;
• in response to the first request:
• freeing a portion of a respective pre-allocated block of the plurality of pre-allocated blocks of GPU memory;
• storing the first data in the portion of the respective pre-allocated block;
• and
• pre-allocating a new block of GPU memory of the client device, the new block comprising a complementary portion of the respective pre-allocated block such that, after pre-allocating the new block of GPU memory, the entirety of available GPU memory of the client device remains allocated.
