oclHashcat64.bin: /usr/lib64/libOpenCL.so: no version information available (required by ./oclHashcat64.bin)

I have been working on a project using oclHashcat this afternoon and started to look into an error that has existed on a development server where we use oclHashcat for quite some time. After some digging around I am confident that regardless of the error existing there is not an issue but I wanted to post an article related to the error in case anyone else looked for a resolution to the error. Below is information on the libOpenCL.so error and my thoughts regarding the error.

CentOS Linux: ATI Stream Compile Error: GL/glu.h: No such file or directory

Today I was doing some testing with OpenCL and needed to install ATI Stream for one of the tests I was performing but I ran into an error during the compile process. The error related to glu.h which was not found during the compile process using make. Below I describe the error in more detail as well as what was done to resolve the error and make the glu.h file available on the server.

CentOS IRQ Errors, Server: kernel: Disabling IRQ #177

Recently we have been doing a lot of testing of oclHashcat on CentOS Linux servers. The oclHashcat application takes advantage of the GPU’s, or Graphical Processing Units, of Nvidia graphics cards or ATI graphics cards. Anyhow one of the servers we have been testing with has four Nvidia 295 GTX’s and at times was receiving an error stating the kernel was disabling the IRQ. Below we describe the error in more detail along with a kernel parameter that was added to resolve the error. Even though we experienced this issue with oclHashcat specifically the error could happen with other applications and/or Linux Operating Systems so the resolution could be the same.
