We report on multi-loop integral computations executed on a PEZY/Exascaler large-scale (immersion cooling) computing system. The programming model requires a host program written in C++ with a PZCL (OpenCL-like) kernel. However the kernel can be generated by the Goose compiler interface, which allows parallelizing program loops according to compiler directives. As an advantage, the executable derived from a program instrumented with Goose pragmas can be run on multiple devices and multiple nodes without changes to the program. We use lattice rules and lattice copy (composite) rules on PEZY to approximate integrals for multi-loop self-energy diagrams with and without masses. GPU results are also given and the performnce on the different architectures is compared.
