Method and a migration component for migrating an application

A non-transitory machine-readable storage medium comprising instructions which, when executed by a processing circuit of a migration component, cause the migration component to perform operations comprising:

• performing by the migration component, for migrating an application executing in a source compute sled to a target compute sled, wherein the application is associated with data stored in a set of source pages of a source local memory of the source compute sled, wherein the data comprises a respective content stored in a respective source page of the source local memory, wherein at least a portion of the data is stored in a set of target pages of a target local memory of the target compute sled when the application executes in the target compute sled after the migration of the application, wherein a memory is capable of supporting the migration of the application, and wherein the memory is excluded from the source and target compute sleds;
• selecting a first sub-set of source pages, wherein a respective source status of each source page of the first sub-set is modified according to a source table of the source compute sled, wherein the source table indicates the respective source status of each source page, wherein the respective source status for any source page indicates that said any source page is modified or unmodified, wherein each source page has a respective utility indication relating to at least one of access frequency, latency, and memory type;
• setting a target table of the target compute sled to indicate that a first sub-set of target pages are modified, wherein the first sub-set of target pages is associated with the first sub-set of source pages, wherein the target table indicates a respective target status of each target page of the target local memory, wherein the respective target status for any target page indicates that said any target page is modified or unmodified;
• migrating the respective content stored in the first sub-set of source pages to the first sub-set of target pages;
• selecting a second sub-set of source pages, wherein the respective source status of each source page of the second sub-set is modified according to the source table, wherein the first sub-set of source pages is different from the second sub-set of source pages;
• setting the target table to indicate that a second sub-set of target pages is allocated in the memory, wherein the second sub-set of target pages is associated with the second sub-set of source pages, wherein the first sub-set of target pages is different from the second sub-set of target pages;
• and
• moving the respective content stored in the second sub-set of source pages to the memory.

A migration component comprising:

• a processing circuit;
• and
• a program memory containing instructions which, when executed by the processing circuit, cause the migration component to perform operations to:
• perform migrating of an application executing in a source compute sled to a target compute sled, wherein the application is associated with data stored in a set of source pages of a source local memory of the source compute sled, wherein the data comprises a respective content stored in a respective source page of the source local memory, wherein at least a portion of the data is stored in a set of target pages of a target local memory of the target compute sled when the application executes in the target compute sled after the migration of the application, wherein a memory is capable of supporting the migration of the application, and wherein the memory is excluded from the source and target compute sleds;
• select a first sub-set of source pages, wherein a respective source status of each source page of the first sub-set is modified according to a source table of the source compute sled, wherein the source table indicates the respective source status of each source page, wherein the respective source status for any source page indicates that said any source page is modified or unmodified, wherein each source page has a respective utility indication relating to at least one of access frequency, latency, and memory type;
• set a target table of the target compute sled to indicate that a first sub-set of target pages are modified, wherein the first sub-set of target pages is associated with the first sub-set of source pages, wherein the target table indicates a respective target status of each target page of the target local memory, wherein the respective target status for any target page indicates that said any target page is modified or unmodified;
• migrate the respective content stored in the first sub-set of source pages to the first sub-set of target pages;
• select a second sub-set of source pages, wherein the respective source status of each source page of the second sub-set is modified according to the source table, wherein the first sub-set of source pages is different from the second sub-set of source pages;
• set the target table to indicate that a second sub-set of target pages is allocated in the memory, wherein the second sub-set of target pages is associated with the second sub-set of source pages, wherein the first sub-set of target pages is different from the second sub-set of target pages;
• and
• move the respective content stored in the second sub-set of source pages to the memory.
