The invention discloses a
cloud data server mixed training method and
system, which are applied to a
cloud data server cluster comprising a plurality of computing resources. According to the method, a model structure, a
data set, a time
delay constraint and an isolation constraint of a training task are analyzed to generate a task portrait, resource configuration, an operation state and an isolation capability of a calculation node are collected to generate a resource portrait, and a co-located interference degree index table of a task and
resource combination is constructed based on historical
monitoring data. During scheduling, a heterogeneous computing power
utilization rate, an estimated
training time delay deviation and a co-located interference degree are taken as indexes, a candidate
resource allocation scheme is subjected to weighted evaluation to generate a mixed training scheduling strategy, and
resource isolation is implemented through container and accelerator multi-instance division. In the operation process, the
training time delay and the actual co-located interference degree are continuously monitored, the scheduling weight and the co-located interference degree index are dynamically adjusted according to the deviation, closed-
loop optimization of multi-task mixed training is achieved, the heterogeneous
resource utilization rate is increased, and time delay default and co-located interference are reduced.
