I believe this error is happening because your simulated memory space (i.e., in the simulator) is not big enough for the application you are running. You mentioned that you were passing in 2GB. My guess is that you want mem_size here:

Not sure actually. I ran into the same problem while trying a cpu benchmark a while back. Maybe others can explain the reason. Sampad Mohapatra , 14 Eyl 2020 Pzt, 22:50 tarihinde şunu yazdı: > Hi Muhammet, > > Yes, the gpu benchmark itself mallocs around 3GB. > But then why does the memory usage

Hi Muhammet, Yes, the gpu benchmark itself mallocs around 3GB. But then why does the memory usage show 30305260 KBytes ~ 29 GB ? What does this value indicate ? Thank you, Sampad On Mon, Sep 14, 2020 at 3:30 PM Muhammet Abdullah Soytürk < muhammetabdullahsoyt...@gmail.com> wrote: > Hi, > > Is

Hi, Is there any chance that the input you provide is bigger than 2GB? If the input size is bigger than the memory size, you cannot simulate it in SE mode (since there is no paging support for SE mode). As you can understand from the error message, you need to increase the size of the memory.

Hi All, I am running 2DConvolution (polybench-gpu) and leela (SPEC 17) using the AMD GCN3 model on a research cluster with around 4 TB of memory. But the simulation ended with the following message: fatal: Out of memory, please increase size of physical memory. Memory Usage: 30305260 KBytes I

This isn't a problem we've seen before, but it's not particularly surprising. I believe we make many small writes to disk (i.e., each object is a separate write). I'm not sure how to fix this, but it might be a place to start. Another place to look is that most of the data written is the contents

2020-09-14 Thread Giacomo Travaglini via gem5-users
Hi Tracy, It’s probably because the m5 binary shipped with linaro-minimal-aarch64.img Is using a reserved m5 instruction which is gem5 specific and it is not recognised by the host. In order to make things work, you need to recompile the m5 binary so that it uses memory mapped operations.

Hi All: Are there any ideas to accelerate the speed of m5.checkpoint on disks? In my NVME ssd , the speed of taking checkpoint is only about 145K/s. [cid:image001.png@01D68AAD.F3323EE0] 李翼超(Charlie) 华为技术有限公司 Huawei Technologies Co., Ltd. [Company_logo]
