gem5

问题 I am working on a program that I need to simulate program that called OpenBLAS functions with gem5 in SE mode. My code(in C) is as below #include <cblas.h> #include <stdio.h> void main() { int i=0; double A[6] = {1.0,2.0,1.0,-3.0,4.0,-1.0}; double B[6] = {1.0,2.0,1.0,-3.0,4.0,-1.0}; double C[9] = {.5,.5,.5,.5,.5,.5,.5,.5,.5}; cblas_dgemm(CblasColMajor, CblasNoTrans, CblasTrans,3,3,2,1,A, 3, B, 3,2,C,3); for(i=0; i<9; i++) printf("%lf ", C[i]); printf("\n"); printf("hello hihi\n"); } which is

问题 I know that the ARM PMU is partially implemented, thanks to the gem5 source code and some publications. I have a binary which uses perf_event to access the PMU on a Linux-based OS, under an ARM processor. Could it use perf_event inside a gem5 full-system simulation with a Linux kernel, under the ARM ISA? So far, I haven't found the right way to do it. If someone knows, I will be very grateful! 回答1: As of September 2020, gem5 needs to be patched in order to use the ARM PMU . Edit : As of

问题 I have to work with gem5 for my project but was wondering that what hardware configuration i should buy. I owned a "good enough" laptop but sadly it's no longer working reliably, so i would have to stick to some lower end laptop. What minimum priced processor i should buy? Also AMD or Intel? Can't afford an apple laptop either. Any help is deeply appreciated 回答1: To give you an idea, I have high end Lenovo P51 laptop with: Intel Core i7-7820HQ Processor (8MB Cache, up to 3.90GHz) (4 cores 8
