The UPMEM Processing-In-Memory solution consists of a pool of programmable co-processors, the DPUs, integrated in the memory.

Content

Examples of DPU programs generated with UPMEM DPU SDK

Requirements

• The UPMEM DPU SDK, version 2019.4.0
• Gnu make and gcc, to build the application

#Building the programs

make to build the programs.

make clean removes the resulting builds.

Executing

The simplest way to execute the programs is to run make test. Otherwise, you may run individual tests manually by executing the binary generated in the build folder of the targeted program.

List of demo programs

checksum

The host application generates a random file of 8MB, and schedules multiple DPUs co-processors to compute the checksum on this file. As sanity check it compares host result with the DPU results, and prints out the DPU performances:

• 1. Total number of DPU cycles executed
• 2. The number of DPU cycles per byte processed

Macros can be used to change the of the program:

• 1. NR_TASKLETS set the number of tasklets used by the dpu program (default: 16)
• 2. NR_DPUS set the number of dpu used by the host program (default: 1)

example: NR_TASKLETS=1 NR_DPUS=DPU_ALLOCATE_ALL make test
