Computation Platform properties

Generic properties describing the Computation Platform aspects.

Common Properties

(Not applicable)

Specific Properties

golem.srv.comp.expiration : Number (int32)

Describes: Demand

Indicates the expiration time of the Agreement which is being negotiated. This is expressed as Javascript timestamp (number of milliseconds since 1970-01-01 00:00:00 UTC, as returned by Date.now()). After this time both sides are allowed to terminate the Agreement; and Provider actually does that.

Expiring vs Perpetual Agreements

For scenarios where perpetual (non-expiring) Agreements are required, eg. long-running services, the golem.srv.comp.expiration may remain unspecified. This indicates the intent of Demand issuer to negotiate a Perpetual Agreement.

Examples

• golem.srv.comp.expiration=1608556352458 - specifies the expiration timestamp of the Agreement.

golem.srv.comp.task_package : String

Describes: Demand

Indicates the URI of a package/binary which is to be executed by the Provider. This is a generic property, which, however, may be interpreted differently per each Computation Platform. Therefore, in a Computation Platform-specific namespace it is expected to specify the semantics of golem.srv.comp.task_package property for that Platform.

Examples

• golem.srv.comp.task_package="hash:sha3:44aba2d41021fac2a3b7af8a3ccfc0a3d4a435f9187ea7d5c162035b:http://64.123.43.186:8000/app-44aba2d4.yimg" - mentioned in Demand indicates that the Requestor expects the Provider to host the binary available from http://64.123.43.186:8000/app-44aba2d4.yimg, with SHA3 hash value as indicated (the example specifies a payload package for a WASM ExeUnit).
