Scalable access to shared files in a distributed system

A method to access shared files, the method comprising:

• accessing, by a bootstrap logic circuitry of a master compute node associated with a user session, an image file of a global filesystem, the image file comprising a first set of one or more files associated with the user session and a second set of one or more files, the execution of the first set depending on the second set of one or more files;
• storing, by the bootstrap logic circuitry, the image file in local data storage of more than one compute node of a spanning tree, the spanning tree of compute nodes comprising one or more compute nodes associated with the user session, wherein the image file is unpacked into a plurality of unpacked files based on data for the image file in the more than one compute nodes of the spanning tree, the unpacked files comprising the first set of one or more files and the second set of one or more files;
• configuring, by the bootstrap logic circuitry, one or more environment variables of a local filesystem service environment of the more than one compute node in the spanning tree, wherein the configured one or more environment variables of the local file service environment is to identify a location in local memory of each of the unpacked files;
• and
• initiating, by the bootstrap logic circuitry after the image file is unpacked, execution of a local filesystem service in the more than one compute nodes of the spanning tree.

A system to access shared files, the system comprising:

• more than one compute nodes coupled, wherein one of the compute nodes comprises a functional block of a root compute node to:
• access an image file of a global filesystem, the image file comprising a first set of one or more files associated with a user session and a second set of one or more files, the execution of the first set depending on the second set of one or more files;
• store the image file in local data storage of more than one compute node of a spanning tree, the spanning tree of compute nodes comprising one or more compute nodes associated with the user session, wherein the image file is unpacked into a plurality of unpacked files based on data for the image file in the more than one compute nodes of the spanning tree, the unpacked files comprising the first set of one or more files and the second set of one or more files;
• configure one or more environment variables of a local filesystem service environment of the more than one compute node in the spanning tree, wherein the configured one or more environment variables of the local file service environment is to identify a location in local memory of each of the unpacked files;
• and
• initiate, after the image file is unpacked, execution of a local filesystem service in the more than one compute nodes of the spanning tree.

A non-transitory machine-readable medium containing instructions, which when executed by a processor, cause the processor to perform operations, the operations to:

• access, by a bootstrap logic circuitry of a master compute node associated with a user session, an image file of a global filesystem, the image file comprising a first set of one or more files associated with the user session and a second set of one or more files, the execution of the first set depending on the second set of one or more files;
• store, by the bootstrap logic circuitry, the image file in local data storage of more than one compute node of a spanning tree, the spanning tree of compute nodes comprising one or more compute nodes associated with the user session, wherein the image file is unpacked into a plurality of unpacked files based on data for the image file in the more than one compute nodes of the spanning tree, the unpacked files comprising the first set of one or more files and the second set of one or more files;
• configure, by the bootstrap logic circuitry, one or more environment variables of a local filesystem service environment of the more than one compute node in the spanning tree, wherein the configured one or more environment variables of the local file service environment is to identify a location in local memory of each of the unpacked files;
• and
• initiate, by the bootstrap logic circuitry after the image file is unpacked, execution of a local filesystem service in the more than one compute nodes of the spanning tree.

An apparatus to access shared files, the apparatus comprising:

• a means for storing, by the master compute node, the image file in local data storage of more than one compute node of a spanning tree, the spanning tree of compute nodes comprising one or more compute nodes associated with the user session, wherein the image file is unpacked into a plurality of unpacked files based on data for the image file in the more than one compute nodes of the spanning tree, the unpacked files comprising the first set of one or more files and the second set of one or more files;
