Concurrency control for remote disaggregated memory architecture

A method for managing memory access, comprising:

• checking, by a client processor, a status field of metadata corresponding to remote data in a memory server as part of a read operation;
• in response to the status field indicating that the remote data is available for reading, discovering, by the client processor, that a pending write exists from another client for the remote data by checking a dirty bit of the metadata;
• in response to the pending write existing, checking, by the client processor, a reference count of the metadata ;
• in response to the reference count matching one of one or more values, changing, by the client processor, the status field of the metadata indicating that an update is in progress;
• in response to changing the status field, sending a merge instruction from the client processor to the memory server;
• receiving, at the client processor, a response that write records are merged with the pending write;
• and
• marking, by the client processor, the status of the remote data as stable by updating the status field of the metadata.

A method for remote access comprising:

• allocating, by a client processor, a region of local memory to update remote data in a memory server, wherein the local memory is within a computing system that includes the client processor;
• in response to the allocation, storing, by the client processor, a write record to the region, wherein the write record stores:
• the update data in a data field;
• and
• a location in one or more location fields, wherein the location denotes where the update data of the write record is to be written;
• and
• in response to storing the write record, flagging the remote data as having a pending update at the location by updating metadata of the remote data to point to the write record.
